Renin is an enzyme that helps control blood pressure and regulate levels of sodium and potassium in the body. Angiotensinogen is the hormone that causes the narrowing of blood vessels. It is released from liver to form angiotensin.
<h3>What is the role of angiotensin?</h3>
Angiotensinogen is a hormone that on hydrolysis forms angiotensin
Angiotensinogen is hydrolyzed by renin enzyme and forms angiotensin.
This angiotensin helps to increase blood pressure by the process of vasoconstriction, increased aldosterone biosynthesis and renal actions.
Thus, it can be concluded renin hydrolyzes angiotensinogen, which is released from the liver, to form angiotensin.

The lack of centrioles in nerve cells prevents them from undergoing mitosis and meiosis, which prevents them from dividing. Nerve cells do not divide throughout their lives and do not lengthen without doing so.

What is nerve cells?</h3>
The central nervous system is constantly receiving information about the external and internal environment (in the form of sequences of action potentials) from nerve cells, also known as neurons.
Nerve cells are “excitable” cells that may convert a range of stimuli into electrical impulses (CNS). Despite the complexity of the nervous system, neurons and glial cells are the only two types of nerve cells that make up nervous tissue.
The structural and operational components of the nervous system are called neurons. Nerve impulses are electrical signals that are transmitted by them. Neuronal support is provided by glial cells.
Therefore, nerve cells do not reproduce and, if damaged by injury or disease, are lost forever.

The correct answer is "<span>immediate and proximal treatment at the disaster site, and expected return to the disaster site".
The immediate and proximal treatment at the disaster site (i.e. warzone) is essential to prevent the early progression of PTSD into more severe forms of anxiety and other neurotic instances; and in some cases, to prevent patients into going psychosis. The expected return to the disaster site is to ensure that the patient has overcome his mental trauma from the event and disconnect the association of the disaster site to the trauma.</span>
Explanation:
Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.
