Explanation:
Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing). The phospholipid in the cell membrane acts as a selectively permeable barrier that regulates what goes in and out of the cell <u>thereby protecting the cell from some external molecules and ions</u>.
Answer:
Two dominant alleles aren't required for it to be expressed as the phenotype. however, two recessive alleles are necessary for the characteristic to be expressed as the phenotype
Answer: distance from the mainland
Explanation:
The size of the island and the proximity of the island from the mainland are two important determinants if island biogeography.
Three factors are considered while discussing island biogeography. immigration, the inflow number of organisms into the island. Increase in immigration increases the rate of immigration.
emigration, on the other hand is the outflow number of organisms leaving the island.
And extinction, is seen as the number of species on the island that become extinct. Extinction rates are related to the size of the island.
Likewise, the farther the island is from sources of immigration (mainland) the less species diversity will be found in that island. This is because the island is more isolated from other plants and animals that could influence the species composition on the mainland.
