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 do the number of chromosomes in cells that go through meiosis and mitosis compare?

34kurt

Answer: Option A is correct.

Cells that go through meiosis have half as many chromosomes as cell that go through mitosis. Meiosis is that's why called REDUCTION DIVISION.

Explanation:

In meiosis, the number of chromosomes becomes half or reduced than the normal while, in mitosis the number of chromosomes remains the same.

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells

UkoKoshka [18]

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.

<h3>What is keratinocytes?</h3>

Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
The skin's epidermis is made up of this kind of epithelium.
