Looking at the data in Figure 1.4 from the Evolution eBook, predict what will happen if a new antibiotic to the food poisoning bacteria Campylobacter jejuni is developed and prescribed heavily by physicians beginning in 2022. Castorocauda, a Jurassic Period mammal and beavers both have webbed feet and a flattened tail, but are not related. 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. That's crazy, right? border-bottom: 10px solid #33ac08; Biologists believe that ducks evolved from land birds that did not have webbed feet. In many species, webbed feet likely evolved to aid in generation of propulsion during swimming. 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. (Rate this solution on a scale of 1-5 below), Log into your existing Transtutors account. #masthead-widgets .widget { width: 100%; } C. Trait T The populations of ducks evolved webbed feet because: (a) The more successful ducks adapted to their aquatic environment. font-weight: bold; The amount of webbing on a ducks feet is a heritable trait.Q6.8. /* ]]> */ Webbed feet are ideal the birds that are capable of swimming on water's surface order underwater. display: block; Webbed feet are ideal for birds that swim, on the water's surface or under. This provides evidence of evolution by natural selection, as well as, In pea plants, the purple flower trait (F) is dominant to the white flower trait (f). They've both evolved to provide the animals with more surface area to propel them through the water better. One of the basic ideas in the theory of evolution is that the more characteristics that are shared by two species: A. the more recently they shared a common ancestor. C. Ducks with less webbing worked harder than ducks with more webbing to eat aquatic plants. DDT is an insecticide that was used extensively in the mid-1900s to kill mosquitoes. margin: 0 auto; The Pythagorean Theorem, a2+b2=c2 a 603. B. Mosquitoes in the population learned to adapt to the high levels of DDT in the environment. box-shadow: none !important; The webbed feet of waterbirds are morphologically diverse and classified into four types: the palmate foot, semipalmate foot, totipalmate foot, and lobate foot. 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 . Explanation: C. The mosquito population needed to evolve DDT resistance in order to avoid extinction. margin-top: 0; She returned every week for 12 weeks to measure survival of tagged lizards. June 16, 2022. /* ]]> */ The Lafayette popu ation has a frequency of allele B 0 and a frequency of allele b = 1. D. In a population in Hardy-Weinberg, there are two alleles at a single locus and one allele is dominant over the other. C. .date { Also known as water hogs or carpinchos, the capybara is a large South American rodent and one of the biggest rodents worldwide. Their feet are webbed and this trait makes them fast swimmers. They were therefore able to eat aquatic plants and get enough food to survive and reproduce.Ducks with more webbing were better at eating aquatic plants than ducks with less webbing, so the ducks with more webbing survived and reproduced better than ducks with less webbing.Ducks with less webbing needed to grow more webbing in their feet in order to improve their access to aquatic plants, which allowed them to survive better and reproduce more.Q6.10. A. Alternatively, divide the length by tan () to get the length of the side adjacent to the angle.Nov 18, 2022. background-color: #f5853b; .entry-content p, .entry-content > ul, .entry-content > ol, .entry-content > li, .entry-content > dl, .entry-content pre, .entry-content code, .entry-content blockquote { Suppose a population is in in which the frequency of the genotype AA = 0.64. Choose all that apply. .widget { Could individuals of a species look different today than individuals of the same species did many generations ago? If mutations arise that affect shell thickness within a snail population, then with crabs present, those mutations: B. 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. 8. HiSET: Math : Data Analysis, Probability, and Statistics Data Analysis, Statistics, and Probability introduces statistics as a problem-solving process. 189.

Most ducks had less webbing on their feet than their parents. padding: 30px auto; Which of the following is REQUIRED for the process of evolution by natural selection to occur? B. b. terrestrial adaptations . An individual's specific set of alleles makes up their , while their is descri d as the individual's physical appearance and other observable characteristics. The ability to be able to move both on land and water is one of them for all expect the Sea Otter. } margin: 1em 0; 50% of the offspring will be pink and 50% will be red, Freshwater snails can be resistant (RR), mildly susceptible (RS) or susceptible (SS) to a parasitic worm. Humans, moles, horses, dolphins and bats forelimbs are all used very differently, however the sequence and arrangement of bones is the same because the species share a common ancestor.
