Answer:

The correct answer will be option-B.

Explanation:

Transfer RNA or tRNA is the RNA molecule associated with the protein synthesis as it adds the specific amino acids to the nascent growing polypeptide.

The structure of the tRNA molecule resembles the shape of a clover leaf and is known as the clover leaf model. The structure contains hydrogen-bonded stems and associated loops. The stems include acceptor stem which posses CCA 3'-terminal group to attach amino acids. The anticodon loop contains an amino acid attachment site. T and D loop contains modified pseudouridine and dihydrouridine.

Thus, Option-B is the correct answer.

Around 40 million years ago

The earliest whales that we think were fully aquatic, that is, they never left the water, are found around 40 million years ago, during the middle Eocene. That means that the transition from terrestrial animals to fully aquatic animals took about 12 million years.

Homeostasis is maintained through feedback mechanisms.<br><br> a. True<br> b. False

Kaylis [27]

Answer:

a. True

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.

During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.

For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.
