Which of the following describes a common hypothesis about why larger animals survive longer than smaller animals? Question 14Select one: b. Larger animals are more likely to eat the smaller animals, therefore there will be less survival stress for larger animals and they must evolve a mechanism to live longer c. Smaller animals are more likely to be predated compared to larger animals, therefore smaller animals must invest more resources into early life development at the expense of longer lifespans d. Smaller animals are more likely to struggle for food (given that they can't out-compete other organisms for food based on their size). This imposes a high level on stress on smaller animals

Which statement is supported by the diagram?Question response areaSelect one optionCarnivores have a shorter life span than herbivores.Carnivores have a higher metabolic rate than herbivores.Animal tissues are digested more easily than plant tissues.Animal tissues contain greater amount of proteins than plant tissues.

Which of the following seems to be true regarding which species survive a mass extinction? Group of answer choicesThe species that survive are luckyThe species that survive are the largestThe species that survive are the most fitThe species that survive are the smallest

Read each of the scenarios below. Then, select the option that best represents a scenario illustrating natural selection.A In a population of birds, those with larger beak sizes are better able to crack open tough seeds, providing them with a food source during periods of scarcity. Consequently, the average beak size in the population decreases.B In a population of flowers, those with a particular color variation attract more pollinators and produce more offspring. As a result, the proportion of flowers with that color variation decreases over generations.C In a population of rabbits, those with longer legs are more successful at outrunning predators and are more likely to survive and reproduce. Over time, the average leg length in the population increases.D In a population of fish, those with brighter colors are more easily spotted by predators, leading to higher mortality rates. As a result, the proportion of fish with bright colors increases over time.

Which of the following is accurate of the relationship between animal body size and metabolism?Question 3Select one:a.Diffusion across the body surface is sufficient to meet metabolic needs in smaller animals with large surface area relative to body volume.b.The need for complex organ systems increases with increased body size.c.All animals have complex organ systems.d.a and be.none of the above

Small populations of organisms are less likely to survive changes in the environment becauseA.individuals cannot find mates in such small populations.B.mutations do not occur in small populations.C.there is not sufficient variation in the gene pool of the population to ensure that some members are better adapted in the new environment.D.natural selection only applies to very large populations.
