Its called homeostasis, the regulation in temperature which can be exhibited thorugh sweating, panting, etc. It helps taking the heat out and all body waste away to regulate the temperature inside an organisms body.
Answer:
c. The ratio of long to short fatty acid tails in the membrane phospholipids increases
e. There is an increase in the saturation state of the fatty acid tails of membrane phospholipids
Explanation:
In biological lipid membranes, the homeoviscosity refers to the process by which the membrane 'adapts' its lipid composition to maintain a proper fluidity. It is well known that the membrane's fluidity increases with increasing temperatures. In this regard, it is important to have into account two points. First, the length of the fatty acid tail alters the membrane's fluidity: shorter fatty acid tails increase fluidity, while longer fatty acid tails decrease it (because shorter tails establish fewer molecular interactions between fatty acids tails). Second, the degree of saturation (i.e., the number of bonds between the carbon atoms) of fatty acids tails also affects homeoviscosity. A higher saturated fatty acid content decreases the membrane's fluidity because saturated tails are arranged in order to maximize molecular interactions between fatty acids tails.

A 70-year-old client with a diagnosis of left-sided stroke is admitted to the facility. To prevent the development of disuse osteoporosis, which objective is most appropriate?
a) Promoting range-of-motion (ROM) exercises
b) Promoting weight-bearing exercises
c) Maintaining protein levels
d) Maintaining vitamin levels
Answer: b) Promoting weight-bearing exercises
Explanation:
The bone is a living tissue that becomes stronger with exercise. Weightlessness and immobility can lead to bone loss.
Weight-bearing exercises are those that force us to work with gravity, like walking, hiking, jogging, climbing stairs, playing tennis, and dancing. They can help prevent disuse osteoporosis.
On the other hand, swimming and bicycling would be examples of non-weight-bearing exercises.
The perivascular feet of the <u>endothelial cells</u> help create a blood-brain barrier.
<h3>What are endothelial cells?</h3>
Endothelial cells can be defined as those type of cells found in the inside lining of blood vessels, lymph vessels, and the heart.
Interestingly, the major function of the edothelial cells is that they release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion.
So therefore, the perivascular feet of the endothelial cells help create a blood-brain barrier.

Answer:
Option B) they lack a nuclear membrane
Polysome formation in bacteria is able to occur because they lack a nuclear membrane
Explanation:
Since bacteria, like other Prokaryotes, lack a well-defined nucleus and nuclear membrane, its ribosomes are held together by ribonucleic acid (RNA) during protein synthesis, and are altogether referred to as polysome.
