Answer:
1. What is vestigial structure?
<u>Vestigial structures are structures that have no obvious purpose and appear to be leftover components from a previous progenitor. The human appendix, a snake's pelvic bone, and the wings of flightless birds are all examples of vestigial features.</u>
2. What is analogous structure?
<u>Analogous structures are characteristics of various species that are comparable in function but not necessarily in form, do not come from a shared ancestral feature (in contrast to homologous structures), and evolved in response to a similar environmental challenge.</u>
3. What is homologous structure?
<u>Homologous structures are physical traits that are comparable in species with a common ancestry but perform radically distinct purposes. The limbs of humans, cats, whales, and bats are examples of homologous structures.</u>
Mutation I believe is the answer
Answer:
Providing energy and regulation of blood glucose.
Sparing the use of proteins for energy.
Breakdown of fatty acids and preventing ketosis.
Explanation:
The main function of carbohydrates is to provide energy and regulation of glucose in the blood. It prevent the use of proteins for production of energy and also promote breakdown of fatty acids and preventing ketosis. Ketosis is a process that occurs when our body doesn't have carbohydrates in sufficient quantity for the production of energy. Carbohydrates are the first biomolecules that are used for energy production.
