Answer:

d. an immediate increase in the concentration of antibodies, followed by a slow decline.

Explanation:

The Primary Immune Response is mediated by antibodies, which are gamma globulin proteins formed by plasma cells (B lymphocytes). Plasmocyte is a differentiated B lymphocyte capable of actively secreting antibodies.

Antibodies are produced with the main function of neutralizing and eliminating an antigen that stimulated their production. This elimination process is done in various ways through complement fixation, opsionization, anaphylactic reaction (mast cell degranulation), substance neutralization, agglutination, etc.

To neutralize the antigen, the primary immune response promotes an immediate increase in antibody concentration. This is usually a quick process.  This concentration usually begins to decline in a slow process, but it will vary depending on the antigen.

Leokris [45]

Insect hormones and their receptors are a focus in pest control and research. Hence, Option B is correct.

Some of the insect hormones such as ecdysone (molting hormone), JH (juvenile hormone) and their analogs can be used for biological  control of pests.

Option A: Hormone receptors are proteins that bind hormones and form hormone receptor complex to maintain cellular activities.

So Option A is incorrect.

Option B: Some of the peptide hormones used in pest control and research. So Option B is correct.

Option C: Peptide hormones interact with only cell surface whereas aminoacid derivatives and thyroid hormones directly interact with nucleus. so Option C is incorrect.

yanalaym [24]

Answer:

D. Nucleus.

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

Proteins on the surface of vesicles determine where the vesicles go.

The nucleus is the cell organelle which provides the instructions for these proteins. It controls all the activities taking place in the cell and the synthesis of proteins.
