Darwin’s Finches: Darwin observed that beak shape varies among finch species. He postulated that the beak of an ancestral species had adapted over time to equip the finches to acquire different food sources. This illustration shows the beak shapes for four species of ground finch: 1. Geospiza magnirostris (the large ground finch), 2. G. fortis (the medium ground finch), 3. G. parvula (the small tree finch), and 4. Certhidea olivacea (the green-warbler finch) the Grants measured beak sizes in the much-reduced population, they found that the average bill size was larger. This was clear evidence for natural selection of bill size caused by the availability of seeds. The Grants had studied the inheritance of bill sizes and knew that the surviving large-billed birds would tend to produce offspring with larger bills, so the selection would lead to evolution of bill size. Subsequent studies by the Grants have demonstrated selection on and evolution of bill size in this species in response to other changing conditions on the island. The evolution has occurred both to larger bills, as in this case, and to smaller bills when large seeds became rare.

The correct answer is Glycogen is the body’s main source of energy, but lipids contain most of the body’s stored energy.
The glycogen is a polymer of the glucose. The carbohydrates are the main source of the energy in our body. The glucose that is left after the normal energy utilisation by the body is converted into the glycogen and stored at various location, but the most of the energy reserves of our body lies in the fats, which is stored in form of lipids.
Amino Acids Are Linked by Peptide Bonds toForm Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
Answer:
The results of the heat wave are the rising of sea levels, the oceans became more acidic, and species disappeared
Explanation:
About 56 million years ago, heat wave occurs due to the increase in the concentration of greenhouse gases which are present in the atmosphere. We know that greenhouse gases such as carbon-dioxide etc were the main cause of global warming. Due to this warming, many temperature sensitive species die, melting of ice occurs which increases the sea level and carbon-dioxide deposition occurs in the ocean water which make the water more acidic and the life of marine animals will be adversely affected.
