Explain how animal behaviors, including human behaviors, are governed by genetic inheritance.
Why do human bodies look so different across the planet? How are they different?
Could individuals of a species look different today chegg? In Module 2 we will dive deep into 3 different AI writing programs to see how each one works and how they can best serve you in your writing endeavors. Give an example of how these mechanisms have impacted evolution in a species. Unlike Darwins finches, in which environmental conditions such as food supply rewarded birds with different beak shapes, the capuchino finches all eat the same type of food and live in grasslands scattered across South America. Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. Course Hero is not sponsored or endorsed by any college or university. Why or why not? 1. Nam risus ante, dapibus a molestie consequat, ultrices a. could individuals of a species look different today. Finally, discover cousin species like Homo neanderthalensis. Why has nature decided to create exactly two genders (for humans and animals) and not 3 or 5 for example? Which of the following histograms show the correct representation of the snail shell thickness data 4, 7, 2, 5, 4, 3? What will most likely happen to the population in terms of natural selection? For example, a shark uses its electrosensory and olfactory organs predominately to interact with its environment, whereas primates are heavily dependent upon vision. Ducks are aquatic birds. Could individuals of a species look different today than individuals of the same sspecies did many generations ago? offspring. How can everyone alive today be the same species if not all populations today have Neanderthal DNA while some people have up to about 4% Neanderthal DNA? It is believed that humans started to transfer information from tools to symbols and from symbols to letters from generation to generation. Would you expect the DNA of the goat to be more similar to? Speciation is the process by which new species form. Q6.5.
Tiny but Mighty- Tarantula | Tiny but Mighty- Tarantula A tiny Posted
Their songs are different, too. See Answer What are the noteworthy differences between the two? There are surprisingly large genetic differences between individuals from the same population; indeed, recent mitochondrial DNA evidence shows greater variation within regional populations than that shown between historical human races. Yes, all individuals can change a little and pass those changes on to their offspring Yes, some individuals can change a little and pass those changes on to their offspring Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring No, species do not change even after many generations, so individuals of the same species would not look different Submit. This changed the way that humans reproduced and evolved, which in turn, changed the way that humans look today. Q7. a. Two major equations of hardy-weinberg rule are: p2 + 2pq + q2 = 1 p + q = 1 The p and the q represent the allele frequencies for Happy and Sad respectively. In evolution, why is it important that individuals vary from each other? \\ e. They are the same species and a. It is their physical features and anatomical parts. If a species is evolving, when is it considered a new species different from the organism it evolved from? Explain. Explain. It's very important, and theoretically you could have a race where everyone has the same genotype for physical appearance. Consider a population that lacks variation and no individual has any advantageous traits.
How species are identified | Dinosaurs | The Guardian Why or why not?Yes, all individuals can change a little and pass those changes on to their offspring.Yes, some individuals can change a little and pass those changes on to their offspring.Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring.No, species do not change even after many generations, so individuals of the same species would not look different.Q6.6. Could individuals of a species look different today than Access to over 100 million course-specific study resources, 24/7 help from Expert Tutors on 140+ subjects, Full access to over 1 million Textbook Solutions, This textbook can be purchased at www.amazon.com, ipiscing elit. Another theory is that individuals of a species could look different today if they had different genetic mutations. Near industrialized areas, black powder covered surfaces, including the moth habitat. To know more check the
In this position, she presents the maximum cross-sectional area and thus maximizes the air-drag force on her. As many years went by, the environment changed such that the aquatic food sources were much more plentiful than those on land. To do this they have inserted a new segment of DNA where the mutated DNA was. How are humans able to affect and alter the phenotypes of other organisms through artificial selection? Gene flow, the movement of alleles across a species' range, is relatively free because individuals can move and then mate with individuals in their new location. DDT is an insectieide that was used extensively in the mid-1900s to kill mosquitoes. Submit your documents and get free Plagiarism report, (Rate this solution on a scale of 1-5 below). Explain why only populations evolve but individuals do not. The known types of human species included: 1. Numerous species in the same region must have recently become extinct. Submit Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination). Why or why not? If mutations arise that affect shell thickness within a snail population, then with crabs present, those mutations:Will result in offspring having thicker shells than their parents.Will result in offspring having thicker or thinner shells than their parents.Will happen because the parents choose to give them to their offspring.Will occur because crabs are present and snails need protection against predation.Q6.4. Nam lacinia pulvinar tortor nec facilisis. Humans all share the same cultural knowledge and beliefs. Why do different genders of the same animal evolve differently? In biology, what is an adaptation? A scientist is researching how to cure a type of blindness that is caused by a mutation in a gene. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. How can similar types of genetic mutation occur in different individuals of the same species? Explain how differences in skin color of humans have been selected for in different environments. After many generations, will all individuals in the population have the same adaptive trait? What is an example of a genetic mutation that created a new species in the modern era that humans have documented? Question Could individuals of a species look different today than individuals : 425869.
Could individuals of a species look different today than individuals of What might scientists say about the human, seal, bird, and bat based on this evidence? A. For the past 10 to 25 years, farmers have planted crop seeds that have been genetically modified to withstand treatment with a common weed killer called Roundup. How do modern biology, evolution, and natural selection explain why there are differences in innate aptitude in animals (such as there are humans who are smarter than others, some are more artistic than others, etc.)? Could a remove () function also be defined for a singly linked list? And yet, at the genetic level they are up to 99.97% identical. Q6.5. C) not all mutations cause visible change. Its individuals appear different from other species. There are at least 4 different ways that humans have genetic variation, a. Any action you may take upon the information you find on this website is strictly at your own risk. Does the question reference wrong data/reportor numbers? B. The smallest and largest snails would be the most likely to reproduce. Some populations are innately superior to others, because they have what it takes to prevail in those environments. Different finch species live on different islands. As you know, the scales of these changes are different. There are a number of factors that could affect whether a species evolves. Describe what has most likely happened over time to lead to this. It was very effective at first, but after a few decades DDT became less effective at killing mosquitoes because many populations had evolved resistance to DDT. While webbed feet were evolving in ancestral ducks, with each generation:Most ducks had about the same amount of webbing on their feet as their parents.Most ducks had more webbing on their feet than their parents.Most ducks had less webbing on their feet than their parents.The amount of webbing on ducks feet had no relationship with the amount their parents had.Q6.9. Some organisms may be very closely related, even though a minor genetic change caused a major morphological difference to make them look quite different. How are humans related to primates? C) albumin Could individuals of a species look different today than individuals of the same species did many generations Most people today would classify such forms as different species, and none of these sibling species mate with one another in normal circumstances. Submit Q6.6. so you can get an accurate answer to your question. 2. Human-made tools of prehistoric times 2.5 million years ago show that humans began to memorize information in steps. Difficulties with Darwin's concept tempted a number of people to try to redefine species by means of interbreeding. This allows the farmers to spray their fields to get rid of weeds without harming their crops. And it is thought to be one of the alien races in contact with earth. Humans have genetic diversity than chimpanzees. e. all living organisms, with just a few exceptions. From one ancestral species that colonized the remote island chain, many new finch species evolved with differently sized and shaped beaks to exploit the foods available. Explain. A disease attacks those plants and wipes them out. A trait with a genetic basis that increases the fitness of an individual with the trait in a particular environment, compared to individuals lacking the trait. For example, when humans first migrated to North America, they were faced with a new environment with different plants and animals. In animals generally, how much variation do you expect to see within as compared to between different races of a single species? A major difference among finch species is in their beaks: both size and shape vary greatly.Assume that a population of one of these finch species is undergoing evolution by natural selection with respect to beak size and shape. Could individuals of a species look different today than individuals of the same species did many generations ago? She likes certain aspects of both types of dog. Considering chimpanzees and humans share 90% of the same DNA, why can't they breed together? What makes humans so different from the rest of the species on the planet?
Population size, density, & dispersal (article) | Khan Academy If there is NO SELECTIVE SURVIVAL based on shell thickness within a population of snails, what happens to shell thickness in response to crab predation?The average shell thickness increases within each generation, but there is no change in shell thickness from generation to generation.There is evolution by natural selection of shell thickness, and average shell thickness increases every generation.There may be evolution of shell thickness, but not through natural selection and not necessarily toward thicker shells.There is no change in shell thickness within the population.Q6.3. People who are heterozygous for the sickle-cell allele: Are not susceptible to either sickle-cell anemia or malaria. 1. What are the impli. DDT is an insecticide that was used extensively in the mid-1900s to kill mosquitoes. not? or nec facilisis. How do bacteria acquire genetic variation, and how does that differ from the mechanism by which humans acquire variation? Discuss both the evolutionary implications/benefits of light skin pigmentation and dark skin pigmentation. To put this another way: all humans have the same genes, yet we do not look alike. Was the final answer of the question wrong? What changes occur gradually over time that indicate the population is evolving?Within their lifetimes, some individual finches beaks change in size or shape.The proportions of finches having different beak sizes/shapes change across generations.Each finchs learned ability to use its beak is automatically passed on to its offspring.All finches in each new generation develop the same new, improved beak size and shape.Q6.5. When we adapt, or evolve over time, does it happen through genetic mutation or something different? Second, the two species would need to have a significant difference in their reproductive capabilities. Therefore, the first concept of the term "species" was based on the morphology. What is biological evolution? Do any of our fossil relatives or other species share some aspects of this unique set of characteristics? Why are these genes similar but not identical? Why don't other animals have as many genetic mutations as humans? Why or why not? Humans share common biological constraints b. How is this best explained?Ducks with less webbing worked harder than ducks with more webbing to eat aquatic plants. Nam risus ante, dapibus a molestie consequat, ultrices ac magna. Fontana, P.L. Could individuals of a species look different today than individuals of the same species did many What causes variation in a species? What are the general characteristics of animals? If so, why did we evolve this way? A species is a group of individual organisms that interbreed and produce fertile, viable offspring. Over one or two generations, beak size among finches increased.
Reciprocal altruism - Wikipedia Are humans particularly self-destructive when compared to other animals? Why do people (and most other species) have two copies of each chromosome? What would such an evolutionary development look like? B) Low levels of genetic variation may make hybrid species more likely, so neither species will go extinct. Similarities at the beginning of embryonic development imply they have common ancestors. There is similar variety for wings and head color, creating an almost mix-and-match effect when the species are viewed side by side. So, how can the males all be so different? Genetic drift b. Gene flow c. Mutation d. Natural selection. First, the two species would need to be geographically isolated from each other. We've gathered the most relevant information and related questions to: Could individuals of a species look different today chegg? Variation in traits that affect which individuals survive and reproduce in each generation is called: a. fatalism b. genetic engineering c. morphology d. catastrophism e. natural selection. If they are met, natural selection automatically results. The 14 species of finches on the Galapagos Islands evolved from a single species that migrated to the islands several million years ago. From a genetics standpoint, why is there such a huge difference in height among humans? Genetic variations that alter gene activity or protein function can introduce different traits in an organism. 0.48. What are the 2 main reasons for variation between organisms of the same species? Finally, the two species would need to be unable to interbreed. Why is it that chimpanzees have 99% the same DNA as humans, yet the one percent distinguishes us to such a degree? In Europe, dark peppered moths were rare before the 1850's and light colored moths were plentiful. 6. The correct answer is (c) Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. Yes, some individuals can change a little and pass those changes on to their offspring. Reduction of the burning of fossil fuels (coal). What is the change in a species over time or the process of biological change by which descendants come to differ from their ancestors called? There is fossil evidence that this . A skydiver of mass 60.0kg60.0 \mathrm{~kg}60.0kg can slow herself to a constant speed of 90km/h90 \mathrm{~km} / \mathrm{h}90km/h by orienting her body horizontally, looking straight down with arms and legs extended. Why or why Now, another group of South American finches known as capuchino seedeaters is helping scientists learn about how, and how fast, evolution works. (a) convergent evolution (b) divergent evolution (c) evolutionary cyclicity (d) uniformitarianism. Fusce dui lectus, congue vel laoreet ac, dictum vitae odio. How do humans influence animal evolution? b. mutation. Are humans subject to the same pressures of natural selection as other organisms? There are two layers to physical appearance - genotype and phenotype. The 14 species of finches on the Galapagos Islands evolved from a single species that migrated to the islands seve Q: Q6.5. Today's AI opinion piece by Kissinger, Schmidt & Huttenlocher is wonderfully thought-provoking. Give a reason why animals must be classified. The graphs below represent her findings.What can you conclude from the researchers results?The hypothesis that longer horns offer greater protection against predation is supported.The hypothesis that longer horns offer greater protection against predation is NOT supported.The experiment is well designed, but the results are inconclusive about the hypothesis.The experiment is not well designed to test the hypothesis.
