B ) the oceanic and continental crust only
Explanation:
The evolution of egg was the most important evolutionary incident which allowed the evolution of the terrestrial animals. The amnion is the layer inside the chorion of the egg which keeps the embryo from drying out.
The formation of this layer completely removed the dependency of the organism to lay their eggs in the water to keep them wet.
This layer allowed the reptiles to lay their eggs on the land as the amnion can protect the embryo from drying out. The other layer of eggs protects the egg from the predators and the pathogens.
Thus, the evolution of the amniotic egg is very important from the evolutionary perspective.
The correct statement is this one: Molecules move from areas of high concentration to areas of low concentration.
This is true also for diffusion outside of organisms, for example diffusion of gases in a room.
The other options are false.

Answer:
The correct answers is - vesicles, microtubules, kinesin
Explanation:
Oxytocin and vasopressin are the hormones that are produced in the hypothalamus in the brain and then transported to the posterior pituitary, at the site of action.
These hormones are released in the vesicles on microtubules by the kinesin, kinesin - 2 more specifically for oxytocin. Vasopressin is also released by the kinesin on microtuble's vesicles.
Thus, the correct answer is - vesicles, microtubules, kinesin
The answer is true. The Species-Area Curve lets us to forecast how many species will keep on if the forest is reduced in size by a stated amount. The y-axis specifies how many species can be preserved in an exact area while the x-axis specifies the area of habitat.
