What is innate immunity? Discuss the barriers associated with innate immunity.
Rama09 [41]

Answer:

Innate immunity is a nonspecific defense mechanisms that play its role as soon as an antigen appear in the body (it is relatively rapid but nonspecific and because of that it is not always effective)

Explanation:

The barries of innate immunity are:

Skin: At Epidermal surface, its protective aspect are keratinized cells that lives on the surface, known as Langerhans cells.

Skin sweat or secretions: Their specific defense is sweat glands and sebaceous glands, and their protective aspect is low ph and washing action.

Mucosal surfaces: they are at the mucosal epithelium, and their protect aspects are nonkeratinized epithelial cells.

Oral cavity: They defend salivary glands through Lysozyme

Gregor Mendel crossed true-breeding plants with green pea pods with true-breeding plants with yellow pea pods. The resulting F1
Alchen [17]

Answer:

A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.

Explanation:

The two true breeding plants in the parental population were homozygous (that is what true breeding means). Therefore, their cross would lead to all heterozygous offspring (see attached punnet square). Green is the dominant characteristic, so all F1 plants had a green phenotype, but Gg genotype.

The F1 cross would therefore be Gg x Gg. See attached punnet square.

The genotypes in the F2 generation are 1 GG: 2 Gg: 1 gg 1

Therefore, the phenotypic ratio is 3 green pea pods (Gg or GG): 1 yellow (gg)

Which of the following events characterizes metaphase of mitosis?
Natalka [10]

A.chromosomes aligning themselves at the equator.

<h3>What distinguishing features of mitosis' metaphase?</h3>

A phase of cell division known as "metaphase" (mitosis or meiosis).Individual chromosomes are typically dispersed throughout the cell nucleus.The chromosomes of the cell condense and move toward one another, aligning in the center of the dividing cell, and the nucleus of the cell disintegrates during metaphase.

<h3>What distinguishes metaphase from other phases?</h3>

Its alignment of a duplicated chromosomes at the metaphase plate, an equatorial plate, is what gives metaphase its name.Via microtubules attached to its kinetochore, one of the sister chromatids is joined to one pole of the cell, and the other sister chromatid is associated to the other pole.
