ikadub [295]

Answer:

D. chemical digestion

Explanation:

In chemical digestion, large food molecules are broken down into smaller particles thanks to the action of enzymes present in the digestive juice, undergoing changes in their chemical composition.

Chemical digestion is a process that occurs with the action of enzymes. It starts in the mouth with the action of the enzyme amylase, which is present in saliva and digesting starch. In the stomach, there is the action of gastric juice, consisting of hydrochloric acid and the enzyme pepsin, which acts on protein digestion.  In the small intestine, the food undergoes the action of substances produced by the pancreas (alkaline substance containing trypsin and chymotrypsin, enzymes that act on proteins) and by the liver (bile, which contains salts that act on the digestion of fat, is produced by liver but is stored and concentrated in the gallbladder).

What is one of the main characteristics of secondary granules in the neutrophilic granulocyte cytoplasm
nydimaria [60]

One of the main characteristics of secondary granules in the neutrophilic granulocyte cytoplasm is that secondary granules will become  pink/tan and will cause the basophilic color to lighten.

Promyelocytes, metamyelocytes, and myelocytes are the precursors of neutrophils, which make up the majority of the white blood cell population. The immature neutrophils are usually found only in the bone marrow.

Myeloid maturation sequence is the next stage of  myelocyte. The cytoplasm of this cell starts to produce specific, secondary granules. If the cell is destined to be a neutrophil these secondary granules will be pink/tan and will further cause the basophilic color to lighten and break up. At the beginning of neutrophilia, these secondary granules are most obvious in the golgi area.

As the cell matures closer to a metamyelocyte, they fill the entire cytoplasm. While the cytoplasm shifts to producing secondary granules it also loses the prominence of its primary granules.

grandymaker [24]

Answer:

By the structure of their cell wall

Explanation:

Fungus cell contain cell wall with a chitin in it. That differs them from animal cell that doesn't have cell wall, but also differs them from plant cell wall which contains cellulose.

Fungus is a eukaryotic kingdom which contains microorganisms such as  yeasts and molds, but also macroscopic forms such as mushrooms.

Fungus are heterotrophic organisms, often decomposers with high  biodiversity.
