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.

How did the Mafia gain the interest and scrutiny of the public?

mihalych1998 [28]

Mafia gain the interest and scrutiny of the public through their unique and fearful actions.

Mafia gain the interest and scrutiny of the public by threatening people in the society as well as killing some of them. The main aim of Mafia is to earn money so they perform many actions in order to gain money from the public such as extortion, kidnapping etc.

The person who gives money to Mafia is safe but that person who refuses to pay money to Mafia will gain the punishment of death so we can say that in this way Mafia gain the interest of the public.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for

Len [333]

Answer:

3/16

Explanation:

According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.

Assuming the eye color is represented by E and the wing shape is represented by W. At F2

EeWw x EeWw

E_W_ - 9/16 (dominant for both eye color and wing shape)

E_ww - 3/16 (dominant for eye color and recessive for wing shape)

eeW_ - 3/16 (recessive for eye color and dominant for wing shape)

eeww - 1/16 (recessive for both eye color and wing shape)

Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be 3/16.
