- Question 10 (1 point) An example of artificial selection is The mating of a horse and donkey to make a mule A pet store owner breeding only the goldfish with the brightest colors Extinction of the dinosaurs The extinction of hundreds of insect species due to loss of rainforest
- Today we know that certain chemicals and radiation alter the structure of DNA, thus changing (or mutating)genes. Genes are the ultimate instructions for the characteristics of an organism. Knowing about genetics, sexual reproduction and that genes can mutate would have helped Darwin to explain which of the following aspect of his theory? survival of the fittest inheritance of acquired characteristics sources of variation natural selection
- Question 8 (1 point) Identify (recognize and select) which of the following are associated with todays Theory of Evolution by Natural Selection: 1. biochemical variety within species 5. environment selects fittest individuals 2. biochemical similarity within species 6. individuals change to fit environment 3. competition for resources 7. overproduction and inherited characteristics passed 4. no competition for resources 8. overproduction and acquired characteristics passed Type your four digit answer in the space below. Just four digits (in ascending order (lowest to highest) and nothing else. __ square square Hide hint for Question 8 This is basically four True/False questions for the price of one Your answer should include 1 or 2,3 or 4,5 or 6. and 7 or 8. I know this seems odd but trust me __
- 3. The fossil record provides evidence for evolution. Choose the statements that correctly describe the evidence for evolution provided by the fossil record. For full marks, you must choose all responses that apply. Marks will be deducted if you choose incorrect responses. A. All ancestral organisms can be found in the fossil record. B. The fossil record shows the appearance and disappearance of species. This supports the evidence that certain species evolved from ancestral forms (such as whales from a terrestrial ancestor). C. More recent fossils are most similar to species alive today. D. Evidence of mechanisms for change are preserved in the fossil record. E. Older layers of rock appear under newer layers of rock. This allows species to be placed in chronological order in the fossil record.
