Answer:

A cell wall is a  structural layer covering some types of cells. It is the external covering of plant cell.

It is tough, rigid or sometimes flexible in nature. It acts as the structural support and also provides protection to the plant by performing the filtering mechanism. Cell wall is made of different composition , like plants have cell wall made up of cellulose.

Cell membrane or the cytoplasmic membrane is a biological membrane that is made up of lipid bi layer with embedded proteins. It is selectively permeable.

The correct answer is:

a cell wall is only included on the plant cell

the cell membrane is included in both plant and animal cells

Explanation:

The cell wall is the outer most integument of the cell. The cell wall covers the cell membrane. The cell membrane is also known as the plasma membrane or plasmalemma. There is no another name for the cell wall. The cell membrane is being in almost all types of cells.

The purpose of the cell membrane is the equivalent as that of the skin. It leaves the elements inside the cell from the outside. The cell membrane provides assistance to the cytoskeleton of the cell, gives shape to the cell, and helps in the formation of tissues by adding the matrix located in the extracellular. It allows the passage of a certain substance.A cell membrane is incorporated by the cell wall which forms the outer most integument.

A nucleus within an ascus undergoes meiosis, producing four haploid spores, which then undergo mitosis, producing eight haploid
natima [27]

Answer:

Four.

Explanation:

Initially four haploid spores are produced by meiosis. We know that during meiosis pairing between homologous chromosomes occurs and this created genetic difference between the divided cells. Exchange of genetic material doesn't occur during mitosis so mitotically divided cells are similar. Thus when spores divide by mitosis and become eight in number, here will be no new genetic difference.

The complete sentence will be -

A nucleus within an ascus undergoes meiosis, producing four haploid spores, which then undergo mitosis, producing eight haploid ascospores. These haploid ascospores contain a maximum of four different genetic types.

How are stem cells able to produce red blood cells, white blood cells and platelets?​
kogti [31]

Explanation:

this is the best I can do for you sorry let me know if this helps any.

When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell. The immature cell then divides, matures further, and ultimately becomes a mature red blood cell, white blood cell, or platelet.
