Describe natural selection and give an example of natural selection at work in a population. Please elaborate or explain in 10-15 sentences, please?
Kin Selection - Ground squirrels will often give a warning call when they see a predator, altering the other ground squirrels to the danger. Calling behavior draws attention to the calling squirrel. This being the case, why would natural selection favor this altruistic behavior? Consider this - female squirrels are 70% more likely to make a warning call than male squirrels. Also consider, male squirrels leave the colony when they reach maturity, while female squirrels stay in the colony they are born in. Explain how natural selection is working here!
Describe the similarities and differences among directional, balancing, disruptive, and stabilizing selection.
Use Verbal description of results from graph and then Interpret the graph for Exclusive range sccenario in foraging lab. The interpretations must include Were the results expected and Did they support the hypotheses? If so, state the biological significance of the results from graph. If the results deviated significantly from expected results, discuss the hypotheses onthe basis of expected results and include an explanation of why this might be so. Lastly, state the conclusions drawn from the experiment and their biological relevance. Hypothesis: In the context of exclusive ranges, the foraging times would be significantly affected by the introduction of competition, as opposed to territoriality. This increased competition was expected to deplete food resources and result in harassment by competing individuals.
Why is "fitness" in selection referred to "relative fitness"? Group of answer choices A_"Relative fitness" refers to fitness of a genotype relative to the environment that organisms are in B_"Relative fitness" refers to fitness of some genotypes relative to other genotypes in a population
write summary on describing a scenario that illustrates one of the three types of natural selection. must include the following: a description of the chosen type of selection, an organism and population,three different variations of a specific trait, and how the population shifted from one version of the trait to another and why.
Which form of conditioning is used most for behavior modification? Why does this form work better? Why would Classical Conditioning help someone in their daily life functioning? Which form of conditioning would you most likely see in a classroom setting? Create your own examples of each form of conditioning. Be sure to include the following information in your answer. In addressing classical conditioning: Identify UCS, UCR, NS, CS, and CR. Discuss any stimulus generalization that you observed. Discuss any extinction and spontaneous that occurred. In addressing operant conditioning: Identify negative and positive reinforcements and punishments. Label the schedule of reinforcement or punishment.
How can behaviors be adaptive? Provide an example that includes support from the five tenants of evolution by natural selection: 1) overproduction of offspring, 2) variation in the population, 3) competition for resources, 4) adaptive advantage for some, and 5) reproduction for those who survive
describe selection, confounding, and information bias provide an example for each
You are working on an undergraduate project, studying an insect species. A recent study showed that the pigmentation pattern used for camouflage is made by an enzyme K. However, it has been shown that, when compared to the Kk individuals, the KK homozygotes would have a higher chance of dying from pigment overdose before growing up, while the kk individuals can easily fall to predation before becoming adults. In fact, when compared to the Kk individuals, the estimated selection coefficients for KK and kk are 0.25 and 0.5, respectively. You are interested in what would happen to these alleles. At present, you have conducted a population survey and have 1000 larvae in your collection. Among them, 360 are KK, 480 Kkand 160 kk. 1)How many larvae would survive to adulthood a) 170 b) 414 c)583 d)750 e)830 2)Following up the previous question, what would be the KK genotype frequency at the adult? a) 0.090 b) 0.270 c) 0.325 d) 0.360 e) 0.529 3)Following up on the previous question,…
67)A small population of wolves is geographically isolated from the next closest population which is more than 200 km away. A disease outbreak kills half of the population, and soon after, the wolf population is decreased by another 25% by trappers. The population is then protected but fails to recover and show high levels of pup mortality. What is this population likely experiencing? Disruptive selection Maladaptive gene flow Purifying selection The founder effect An extinction vortex
C28. Do the following examples describe directional, disruptive, balancing, or stabilizing selection? A. Polymorphisms in snail color and banding pattern as described in Figure 24.13 B. Thick fur among mammals exposed to cold climates C. Birth weight in humans D. Sturdy stems and leaves among plants exposed to windy climates
