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.
Answer:
Petroleum gas is mainly C3 and C4 based (propane and butane), whilst natural gas is predominantly C1 and C2 (methane and ethane). Petroleum gas is generally produced via the cracking of naphtha, which is one of the components separated during crude oil refining.
Explanation:
Answer:
both characteristic represent mitosis
The three organisms that belong in the same phylum as your Protist are:1. Algae: Algae are plant-like Protist and are all photosynthetic Protists. 2. Protozoa: Protozoa are animal-like Protists3. Heterotrophs: Heterotrophs are fungi-like Protists. An example is what is known as True Slime Moulds.
A Protist is any organism that is not a plant, animal or fungus. They are normally unicellular, although some can be multicellular, for example, Algae. They all have a nucleus and they mostly live in water.
Answer:
A. the root is continuing to grow so the cells are going through mitosis
