This injury is fatal because, The phrenic nerve regulates breathing and operates the diaphragm.

<u>Explanation:</u>

The motor ability is provided by the Nerve called Phrenic nerve to the diaphragm. This is a muscle that is very important for the respiration to take place in human. When a damage or injury occurs to the Phrenic nerve, it may result in the paralysis of diaphragm.

When this is damages there may be difficulties in breathing and only small amount of air can be inhaled. Thus the paralysis of this nerve results in the prevention of the victim to find difficulties in respiration. Thus, the example given is fatal because, the phrenic nerve regulates breathing and operates the diaphragm.

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.
