Fill in the below mention blanks with immunity. Immunity types may be used more than once, but each sentence has only one correc
sp2606 [1]

Answer:

to. 1. Cell-mediated immunity Cytotoxic T lymphocytes attack and destroy foreign cells and viruses Antibody-mediated immunity

b.1. Cell-mediated immunity T cells mature in the thymus before they circulate. Immune.

C. 1. Cell-mediated immunity B cells differentiate into plasma cells.

re. 2. Antibody-mediated immunity Antibodies adhere to specific targets.

me. 1. Cell-mediated immunity B cells mature in the red bone marrow before they circulate the antigen.

f.1. Cell-mediated immunity Memory T cells are subsequently activated by the same 6 antigens.

g.3. Immune surveillance NK cells monitor peripheral tissues for cancer and abnormal cells.

Explanation:

Cellular immunity is mediated by the cells of the immune defense, it presents different times, in the first time the PMN appear, in the second time the antigen presenting cells, and lastly the lymphocyte lineage.

Antigen presenting cells have the ability to phagocytose and express antigen on their surface to facilitate the formation of antibodies.

Surveillance immunity refers to the lymphocytes that are responsible for monitoring or controlling cell mutations or uncontrolled growth due to genetic mutations.

Neoplastic cells express histocompatibility complexes on their surface that make them recognized by these lymphocytes and this is how they are responsible for inducing self-destruction or phagocytosis of the neoplastic cell.

Humoral immunity refers to the chemical substances that function as mediators of cell activity, these are: pro and anti-inflammatory cytokines, complement chain, nitric and nitrous acid, oxygen free radicals, interleukins, growth factors and tumor necrotic factor alpha - beta

What would happen if there were no buffers in human cells
Elenna [48]
<span>A buffer system is a system that keeps pH constant. This is very important in our cells because all of our enzymes needs a specifik pH value to work at optimum. If the pH changes our enzymes might denaturate which means death</span>

Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a hi
Ilya [14]

C

The inner membrane of the mitochondria is folded to increase surface area for the larger number of protein complexes involved in the Krebs cycle of cellular respiration.

Explanation:

One of the important transmembrane proteins of the inner membrane of the mitochondria is the ATP synthase. Protons are usually pumped to the intermembrane space of the mitochondria. This potential energy is harnessed by the ATP synthase (as the protons flow back to the matrix ) to create ATP. If the inner membrane did not have such as large surface area, they would be fewer ATP synthases and the mitochondria would be less efficient in tapping proton motive force to create ATPs.

A person with such mitochondria would easily get tired from physical activities because they are fewer ATPs to power the muscles and cells' activities especially when energy is highly demanded.
