Answer:

A virus is a tiny infectious agent that reproduces inside the cells of living hosts. When infected, the host cell is forced to rapidly produce thousands of identical copies of the original virus. Unlike most living things, viruses do not have cells that divide; new viruses assemble in the infected host cell. But unlike simpler infectious agents like prions, they contain genes, which allow them to mutate and evolve. Over 4,800 species of viruses have been described in detail[1] out of the millions in the environment. Their origin is unclear: some may have evolved from plasmids—pieces of DNA that can move between cells—while others may have evolved from bacteria.

Viruses are made of either two or three parts. All include genes. These genes contain the encoded biological information of the virus and are built from either DNA or RNA. All viruses are also covered with a protein coat to protect the genes. Some viruses may also have an envelope of fat-like substance that covers the protein coat, and makes them vulnerable to soap. A virus with this "viral envelope" uses it—along with specific receptors—to enter a new host cell. Viruses vary in shape from the simple helical and icosahedral to more complex structures. Viruses range in size from 20 to 300 nanometres; it would take 33,000 to 500,000 of them, side by side, to stretch to 1 centimetre (0.4 in).

The primary immune response involves _________
vagabundo [1.1K]

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.

If there were no decomposes, which of the following would most likely happen?
mars1129 [50]

Answer:

Imagine what would happen if there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.

What do you think about your own water use in our country
madam [21]
I think this is a personal response that you should answer yourself. You are thinking about how you use water wisely and how you waste it. I don’t think others can tell you that unless they know you.

Hey! I believe it is Hurricane. Because that is the one where it affects the water places the most. And would be the one that would destroy turtle nests and hatchlings.
