It is important that the phospholipid bilayer is both hydrophobic in the surface and hydrophilic inside to control and manage the incoming organic compounds mainly water from exceeding the needed amount or destablizing the concentration established by the cells.
Hydrophilic is a characteristic of an object which is attracted to water or can synthesize with water. In contrast to hydrophobic like fats, oils and lipis which has a strong aversion and dislike to water molecules.
Transmembrane proteins are found in the plasma membrane. Hydrophilicregions are embedded within the membrane, and Hydrophobic regions project from both surfaces of the bilayer.
Approximately 20-80% of the cell membrane is composed of lipids, the rest, is made up of protein. The lipid layer of the membrane gives it flexible and permeable characteristic. While the protein part assists in transport of molecules it needs to survive.
Answer:
The answer is <u><em>D)</em></u>
Explanation:
Viruses depend on the host cells that they infect to reproduce. ... When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products.
Answer: C) gas bubbles
Explanation:
An abiotic factor is the factor which influence the life of living beings on earth. The formation of gas bubbles inside the swamp is the example of abiotic factor.
The gas bubbles are formed inside the swamp, marsh or bog. It consists of the mixture of hydrogen sulfide, carbon dioxide and methane. These gases produce naturally in these water bodies due to anaerobic digestion and fermentation of the animal or plant matter inside the water body which results in the formation of bubbles in the body of water.
