Question 11 Which of the following statements is TRUE? Predation exerts a selective force on the prey, favoring characteristics that reduce the probability of capture. Predation only favors the prey with the evolution of more efficient ways to escape predators. Predation only favors the predator with the evolution of more efficient ways to catch prey. Predation exerts a selective force on the predator, favoring characteristics that reduce the probability of prey capture. Question 12 When the relative abundance of an organism is used to determine the overall health of an environment, that organism is referred to as aln).

Animal activity level Low High An organism's activities can change at regular time intervals, called biological rhythms. The graph below depicts the activity level of a population of animals over a 48-hour period. Use the data presented in the graph to answer each of the following questions: (8 points) Midnight 4 A.M. 8 A.M. Noon 4 P.M. 8 P.M. Midnight 4 A.M. Time of Day 8 A.M. Noon 4 P.M. a. Identify and describe two factors that could affect the physiology and/or behaviors of the animal to result in the observed pattern of activity. b. Select one of the factors and make a prediction regarding its effect on the activity cycle of the animal. Justify your prediction with evidence. 8 P.M. Midnight

The Tibetans and Han Chinese share several genetic traits and DNA. However the EPAS1 gene which increases the ability of red blood cells carry oxygen even in low environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is commonly in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in 3-5 sentences

Producing fewer eggs than the Lack number can be explained by (select all that are correct)   Question 4 options:   Egg production is never lower than the Lack number   Trying to avoid attracting a predator   Gene flow   Yearly variation in the environment   Producing larger eggs

In a population of solitary and independent birds, birds occasionally will build nests close to each other. Females will provision their young with food, but may not have enough for themselves. The bird may try to obtain additional food from their neighbors by visiting their nest. Occasionally the neighbor may share some of its food with the visiting bird. What is necessary for this altruistic behavior to persist in this population and why?

The type III survivorship curve is found in species in which most individuals die when they are young but a relatively small number of older individuals can live for a long time.  Many of these organisms have very long lifespans.  This would appear to contradict the evolutionary theory of aging because most individuals die when young but lifespan is long.  How can you explain this apparent contradiction. Group of answer choices -older, larger individuals have most of the offspring -all type III organisms have very slow metabolisms -type III organisms are trying to prove evolution wrong -type III organisms die at a constant rate
