According to proteomic data analysis, the N-terminus residues highly influence the retention of amino acids due to their role in ion-pairing. Every amino acid has a retention coefficient factor depending on the N-terminus residues it contains. Therefore, the longer the amino acid the higher the likelihood of it having high N-terminus residues and consequent high retention co-efficient.
The characteristics of most unsaturated fatty acids found within a human cell are deprotonated carboxylic acid and cis double bonds.
- With the exception of steroids, fatty acids are carboxylic acids that provide the structural foundation of fats, oils, and all other types of lipids. More than 70 have been found in the natural world.
- They are typically unbranched, contain an even number of carbon atoms (often 12–20), and can be divided into groups based on the existence and quantity of carbon–carbon double bonds.
- As a result, saturated fatty acids don't have any carbon-to-carbon double bonds, while monounsaturated fatty acids have one, and polyunsaturated fatty acids have two or more.

For example, insects use wings to fly like bats and birds, but the wing structure and embryonic origin is completely different. <u>These are called analogous structures</u>

Answers & explanation:
I - False
A sympatric speciation can occur commonly in both animals and plants. Sympatric speciation events are very common in plants because it is normal for them to develop multiple sets of chromosomes.
II - False
Sympatric speciation occurs without geographic variation. When two populations of the same species live in the same area but there is no crossing between populations, sympatric speciation occurs.
III - True
Sympatric species may indeed lead to the formation of new species. Sympatric speciation is believed to be responsible, for example, for the large number of cichlid fish species found in Lake Victoria on the African continent. According to research, this lake was colonized by only one ancestral species.
Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically. They change so much that they become an entirely new rock. Figure 4.22: The platy layers in this large outcrop of metamorphic rock show the effects of pressure on rocks during metamorphism.
