Answer:

Basophils

Explanation:

Basophils are the granular leukocytes that make 0-1% of the total white blood cells. Basophils are 10–12 μm in diameter and are the spherical cells with lobed nuclei. When Wright stained, basophils appear to have large, irregularly shaped, deep-blue granules in their cytoplasm. These granules take up the basic stain and hence these cells are called basophils.

Basophils release histamine and heparin. Histamine is associated with allergic reactions. Histamine also dilates blood vessels and triggers contraction of smooth muscle. Heparin inhibits clotting and promotes blood flow. Together, histamine and heparin promote blood flow to injured tissues.

Ceruminous glands are ________. Ceruminous glands are ________. saliva glands found at the base of the tongue modified taste bud

kogti [31]

Answer:

Modified apocrine sweat glands

Explanation:

The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.

As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.

This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.

The inheritance of eye color in Drosophila is controlled by genes on each of the fly's four chromosome pairs. One eye-color gene

algol [13]

Answer:

F1 Females - all wild type

F1 Males - all wild type

F2 Females - - all wild type

F2 Males - 1/2 wild type, 1/2 vermilion

Explanation:

The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.

Female flies have two X chromosomes, male flies have one X and one Y chromosome.

A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).

The female parent can only produce Xᵛ⁺ gametes.

The male parent can produce either Xᵛ or Y gametes.

When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).

The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.

When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:

Xᵛ⁺Xᵛ⁺ females with wild type eyes
Xᵛ⁺ Y males with wild type eyes
Xᵛ Xᵛ⁺ females with wild type eyes
Xᵛ Y males with vermilion eyes
