Phoenix [80]

Answer:

SER, they are capable of synthesizing testosterone of Adrenocortical cells.

Explanation:

Adrenal smooth microsomal cells are  enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.

How is a secondary immune response different from a primary immune response?
borishaifa [10]

Answer:

The secondary immune response is the immune response when the same antigen , memory cells that was encountered before is remembered and the immune system make antibodies to counter it.

Explanation:

There is a difference between the primary immune response and secondary immune response.

In the primary immune response occur when the immune system encountered an antigen for the first time which lead to the generation of memory cells and and the B cells with the T cells produce antibodies.

While the secondary immune response occur when the same antigen that was encountered the first time is encountered the second time and it lead to the stimulation of memory cells to produce more and high quantities of antibodies to fight foreign substances.
