Answer:

Histamine is a substance that is released by the body during an allergic reaction. Mast cells, which are a type of white blood cell, release the histamine, and this triggers a process which is most commonly referred to as the “inflammatory immune reaction”.

Explanation:

Antihistamine solutions can reduce allergies. I am allergic to mosquito bites.

The cells release histamine during allergic responses are the mast cells.

Eosinophils, mast cells, and basophils all have been first diagnosed and defined with the aid of using Paul Ehrlich withinside the past due nineteenth century. Since then, it has end up clean that those 3 cells kinds have an awful lot extra in not unusualplace than their popularity with the aid of using the equal scientist.

Mast cells are multifunctional bone marrow-derived tissue-residing cells which might be the principal manufacturer of histamine withinside the frame. H1R are expressed in lots of cells, along with mast cells, and are concerned in Type 1 hypersensitive reaction reactions.

Answer:

Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.

Explanation:

Hope this helps.

Each daughter cell has 23 of the 46 chromosomes. Sister chromatids make up each chromosome. Daughter cells enter meiosis II, the final step. Two haploid cells result from meiosis I.

Meiosis is a specialized kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.

There are 46 chromosomes total, and each daughter cell has 23 of them. Each chromosome is composed of two sister chromatids. In the second and last stage of meiosis, daughter cells participate. Meiosis I always results in the formation of two haploid cells.

Answer:

By using genetic engineering to insert the gene for the desired enzyme into the bacterial chromosome, then growing large amounts of the modified bacteria in fermenters.

Explanation:

Answer:

Bacteria such as fungi or algae are inserted in fermenter and feedstock such as glucose, amino acid, sucrose are inserted to be a source of food for them.

Then they are left for a time for the bacteria to reproduce more and to produce more enzymes in their cells, Then if the enzymes are extracellular they are extracted directly from the filtrate, if they are intercellular they are separated from the feedstock and crushed to be separated with any solvent such as water.

Explanation:

Eukaryotic cells rely on the molecular energy of ATP to sustain all of the reactions necessary to maintain life, in the absence of ATP, these reactions would come to a halt, and the cell would inevitably die.

ATP is a molecular compound that provides the energy needed by most cells to survive. ATP represents Adenosine triphosphate, which is an organic compound that provides energy to drive the essential metabolic reactions of living cells, such as:

In the situation in which a cell was to run out of ATP, these reactions would stop, given that they require ATP to function. This means that the cell would not be able to send or receive nerve signals, absorb the nutrients it needs, or even create necessary compounds such as proteins. The stoppage of these functions would lead to the death of the cell.

If an experiment was being conducted using an enzyme that was very sensitive to changes in pH, a buffering solution must be added in order to prevent the enzyme from denaturing. Thus, the correct option for this question is A.

The denaturation of an enzyme may be defined as a process through which a molecular structure of an enzyme gets deviate from its original state due to exposure to high temperature, pH sensitivity, etc.

The function of a buffering solution is to stabilize the pH of the given solution. It helps the other component of the solution to resist in response to pH change. A Buffer solution is capable to neutralize the effect of the small amount of acid or base.

Therefore, a buffering solution must be added in order to prevent the enzyme from denaturation. Thus, the correct option for this question is A.
