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 AND Explanation:
A steroid is an organic macromolecule that is biologically active with four rings arranged in a specific molecular configuration. Steroids are important components of cell membranes which alter membrane fluidity and act as signaling molecules. The two main types of steroids are corticosteroids and androgenic steroids like testosterone and estradiol.
<u>Answer:</u>
<em>The intertidal zone is a region of extreme conditions and the organisms should have special mechanisms to cope up with the extreme conditions.
</em>
<u>Explanation:</u>
Low tides expose an intertidal zone to air while high tides cover the intertidal zone with ocean water. When exposed to air the intertidal region is <em>directly exposed to the sun and there will be high temperature. </em>
Thus the animals have to cope up with the extreme heat and also have to face colder environment when under the sea. <em>Since there is change in salinity the organisms have to handle this as well.</em>
Some animals with shells close their shell tightly to seal moisture. Animals like <em>snails and crabs have thick outer covering to prevent water loss by evaporation. </em>
Organisms like leaf barnacles cluster together to avoid individual exposure. <em>Animals like sea stars cling to the rocks to avoid being washed away by the waves.
