Answer:
A phospholipid
a. has both polar and nonpolar regions.
Explanation:
Phospholipids, as amphipathic molecules, consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged hydrophilic (water-loving) polar head, which face outward and are attracted to the intracellular and extracellular fluid. The fatty acids are the uncharged, hydrophobic (water-fearing) nonpolar tails, which face the inside, away from the water and meet in the inner region of the membrane.

Answer:
In the ocean
Explanation:
Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.

Answer:
The trait is Y-linked
Explanation:
The only plausible explanation behind the inheritance pattern shown by the porcupine trait is that it is <u>Y-linked</u>.
<em><u>Y-linked traits are limited to the Y chromosome only</u></em><em>, a sex chromosome that is peculiar to only the male gender. Chromosomally, females are XX while males are XY. Hence, only the male gender has the genetic capacity to inherit the porcupine trait. This is why only the sons of Edward Lambert, and never the daughters, exhibited the trait. </em>
