- Evaluate the following statements about seeds from two biology textbooks: I. The seed coat is an adaptation that protects the plant embryo from damage, water loss, and infection. II. Evolution has come up with a clever solution for protecting plant embryos: seed coats that prevent damage, water loss, and infection. Do these statements accurately represent the evolution of seeds? a) Yes, both statements are accurate. b) No, neither statement is accurate. c) Only the first statement is accurate.arrow_forwardWhy do you suppose plants and forests appeared in large numbers before large animals did? Several of the choices may be correct. Select the options you expect to be the strongest contributing factors.Choose one or more: A.The increased oxygen levels produced by land plants accelerated animal evolution. B.Plants were driven to land by scarce resources in the oceans, such as light and minerals. C.Plants had to change less to survive on land. D.It was too cold for animals at first. E.There was not enough oxygen for lungs to be effective before plants colonized land. F.The order was pure chance and could have gone either way. G.Animals need food, and there was none on land before plants. H.Animals are more susceptible to radiation and needed more ozone in order to survive out of the water.arrow_forwardAncestral wild wheat varieties have a trait where seed heads shatter when ripe, allowing easier seed dispersal. When humans domesticated wheat, they selected for a mutation that reduced shattering so that harvesting the wheat seeds was easier. Use Darwin’s 3 principles of natural selection to compare how this trait evolved in wild wheat and was artificially selected for in domestic wheat.arrow_forward
- In several pairs of plant and animal species, plants have become modified such that only its animal partner can pollinate it, and the animals have become modified such that they are especially well adapted to pollinate just their plant partner. What is the name of this type of evolution that results in two organisms becoming particularly adapted to and dependent on each other?arrow_forwardEvolution results in an increase of organisms that are A. larger. B. more complex. C. better suited to the current environment. D. better able to adapt to changing environments.arrow_forwardDON'T EXPLAIN, JUST GIVE THE ANSWER According to Charles Darwin, organic evolution is "descent with modification," which simply means Select one: A. inherited variations decline as reproductive potential is modified. B. characteristics acquired during the lifetime of an individual are passed on to all descendants of the individual. C. the fittest always impose change on the less fit. D. populations change over time.arrow_forward
- Which of the following individuals would be considered to have the greatest evolutionary fitness? a. Olympic speed skater with one child b. an overweight person with three children c. a woman who had six children, none of whom (the children) survived to adulthood d. a single mom who adopted eight childrenarrow_forwardAssume you are studying two different species of plants that have evolved purple flowers. You reconstruct the ancestor of these plants and discover the ancestor plant had pink flowers. You decide to investigate the development of the purple flowers and find that the plants both evolved purple flowers via the same purple pigment gene pathway. This discovery is best described as which of the following? a. Equal Fitness Landscapes b. Heterochrony c. Parallel Evolution d. Convergent Evolutionarrow_forwardA farmer uses an herbicide called triazine to control pigweed in his field. Initially, the triazine works well and almost all the pigweed dies; but after several years, the farmer sees more and more pigweed. Which of these is the best explanation for what happened? Group of answer choices: Natural selection favored triazine-resistant pigweed, which was more likely to survive and reproduce. Some pigweed plants adapted to become resistant to triazine and passed the trait to their progeny. Natural selection caused the pigweed to mutate, creating a new triazine-resistant species. The herbicide company lost its triazine formula and started selling lower-quality triazine. Triazine-sensitive pigweed is less efficient at photosynthesis.arrow_forward
- Which of the following does not apply to mutations?a. They occur to cause adaptive changes in response to the environment.b. They are usually either harmful or neutral.c. They are only inherited if they occur in a sperm or egg cell.d. They often occur when DNA is copied.arrow_forwardA consortium of dairy and beef farmers has hired you to study the evolutionary origins of domestic cattle. They particularly want to know whether the humped zebu cattle of Asia and the cattle of Africa are derived from different species of wild cattle than European breeds. Outline a complete research program to study this question. Describe the sequence of steps you would need to do, what kind of data you would collect, and the methods you could use to evaluate possible trees and branches.arrow_forwardAccording to Darwin’s theory, organisms that are the most fit A. have the longest life spans. B. have the best overall health. C. produce the highest number of viable offspring in their lifetimes. D. are best suited for capturing prey and avoiding predators.arrow_forward
