Answer:
b). activation of T cells
Explanation:
An APC (antigen-presenting cell) can be described as an immune cell, which detects, uptakes, and informs the acquired immune response when an infection takes place. B cells, macrophages, and dendritic cells are antigen-presenting cells.
These cells play an important role in activation of T cells. T cells are unable to recognize soluble or free antigens and can only recognize antigens processed and presented by carrier molecules, such as MHC molecules.
Presence of MHCII molecules is a defining feature of APCs that process and present antigens to T cells. Hence, all antigen-presenting cells help in activation of T cells.
Thus, the correct answer is option (b).
B) No, many microorganisms, like those in your gut, are beneficial
As is turns out there are only about 100 different bacteria which are pathogenic. All other bacteria are completely harmless and, as this question states, some are crucial for proper human health as we exist in a symbiotic relationship with them. Bacteria in the large colon provide nutrients to us, and play an important role in the development of the immune system.
<span>Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this classification is outdated. Archaeal cells have unique properties separating them from the other two domains of life, Bacteria and Eukaryota. hope that helped</span>
Plants take nitrogen from the soil by absorption through their roots as amino acids, nitrate ions, nitrite ions, or ammonium ions
Magnesium is the powerhouse behind photosynthesis in plants. Without magnesium, chlorophyll cannot capture sun energy needed for photosynthesis.
Answer:
Yes.
Explanation:
Yes, Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health because necessary steps can be taken in order to prevent the disease from more spreading and cause damaged to the body. Identification of genetical disease can be prevented to cause damage if the factors that triggers the disease can be avoided so we can conclude that identification of genetically influenced health risks can increase the chances of getting good health.
