Answer:
Gerontology is the scientific study of the processes and phenomena of aging. Sociologist are interested in social gerontology because it affords them the opportunity to study the non-physical aspects of the aging process.

Answer:
The three methods are: 1) Using H-Ras- SREBP- 2 Fusion proteins, the NH2 segment can be released by two sequentia
Explanation:
Sterol regulatory element binding proteins (SREBPs) are transcription factors attached to the endoplasmic reticulum. The NH2-segment, which activates transcription, is connected to membranes by a hairpin anchor formed by two transmembrane sequences and a short lumenal loop. Using H-Ras–SREBP-2 fusion proteins, we show that the NH2-segment is released from membranes by two sequential cleavages. The first, regulated by sterols, occurs in the lumenal loop. The second, not regulated by sterols, occurs within the first transmembrane domain. The liberated NH2-segment enters the nucleus and activates genes controlling cholesterol synthesis and uptake. Certain mutant Chinese hamster ovary cells are auxotrophic for cholesterol because they fail to carry out the second cleavage; the NH2-segment remains membrane-bound and transcription is not activated.
Answer:
The correct option is: A. pulmonary circulation
Explanation:
The heart is muscular organ that is present in the central compartment of the thoracic cavity. It is responsible for pumping blood in the circulatory system through the blood vessels.
The right atrium of the heart pumps the deoxygenated blood received from the body into the right ventricle, which further pumps the received deoxygenated blood into pulmonary artery that carries the deoxygenated blood to the lungs.
The pulmonary veins then carries oxygenated blood from the lungs to the left heart. This is known as the Pulmonary circulation.
<u>Therefore, the right heart acts as a pump for the pulmonary circulation.</u>
