Answer: Several homozygous recessive individuals leave the population.
Answer:
The terms old world and the new world are used in the context of history and for the prime objective of differentiating the major ecozones found on the planet. This also helps in categorizing various species of plants and animals that originated in different places and times.
In terms of old and new, Old World signifies to Asia, Europe, and Africa, on the other hand, the New World signifies towards the Americas that comprise South America, North America, and Central America. The New World monkeys possess prehensile tails, while the Old World monkeys don't. This suggests that the prehensile tail originated in the monkeys found in the New World, primarily after the separation of the Americas from Asia and Africa.
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.
Hope this helped!
