Answer: The correct answer is A). Is mostly lipid while the whole cell is mostly aqueous .

This is because the cell membrane is majorly composed of the phospholipid bilayer. It is a protective covering present in all the cells.

On the other hand, the whole cell other than the cell membrane is mostly aqueous. It contains 80% of water, therefore considered as aqueous. It is also referred to as cytoplasm of the cell. Most of the cellular activity including metabolic processes and signaling pathways occur within the cytoplasm of the cell.

The composition of a cell differs from that of the cell membrane in that the cell membrane is mostly lipid while the whole cell is mostly aqueous.

Further Explanation:

Cell is surrounded by the cell membrane made up of lipid bilayer. The fluid mosaic model states that the cell membrane is made up of two layers of lipid and the proteins present externally, internally and in the transmembrane.

The lipid molecules are amphipathic having polar head and non-polar tail. The fatty acid present in the lipid may be saturated or unsaturated. Saturated fatty acid has presence of single bond while unsaturated one has double or triple bond present in them.

The protein present in the lipid bilayer can act as the channel molecule or receptor molecules.

The cell contains various cell organelles such as nucleus, mitochondria, chloroplast, ribosome, endoplasmic reticulum, Golgi bodies. Mostly the cell contains fluid inside it called as cytoplasm. The cell organelles are suspended in the aqueous solution of the cytoplasm. Various chemical reactions occurs in the cytoplasm of the cell.

Which statement most correctly describes surrogacy

Alchen [17]

The statement that most correctly describes surrogacy is C, fertilizing sperm and egg in a lab and implanting it into another woman's uterus. This is the definition of gestational surrogacy, which involves In Vitro Fertilization. Gestational surrogacy also means the carrier is not genetically related to the baby, only the father.

How does natural selection “drive” evolution?

yanalaym [24]

Because predators and prey must learn (or adapt) new ways of survival. Deer over time have learned to be much more sensitive to the surrounding environment, therefore, a deer's predator must also adapt/evolve and learn how to beat the deer at it's own game and catch it for food. Animals must evolve/adapt to any given environment. If humans lived in Antarctica for thousands of years, we would eventually be able to withstand the cold due to evolution. People who live in the Himalayas today actually breath normally at such high altitudes whereas if someone who lives at sea level went to where the Himalayan people lived, the result could potentiality be fatal because the body has not adapted/evolved at that point to withstand minimal oxygen.
