Answer:
Helper T cells (CD4+)
Explanation:
In the case of hummoral immunity, Helper T cells help in the differentiation of B cells into plasma B cells . The plasma B cells are then involved in the production of antibodies for specific kind of antigens. In the case of cell-mediated immunity helper T cells are involved in releasing cytokines and help differentiate the T cells into cytotoxic T cells. In the case of cell mediated immunity, the affected cell undergoes the process of lysis.
Answer:
The correct answer will be option-E
Explanation:
The structure of DNA revealed by Watson and Crick showed that Two strands of DNA are present in the intertwined state forming helix representing DNA as a double helix.
Each strand of DNA is made up of the monomer unit of DNA called nucleotide where each nucleotide binds to another nucleotide through weak covalent bond called phosphodiester bond.
The phosphodiester bond is formed between the 3’-OH group of one nucleotide to 5’ phosphate group of another nucleotide. In this way, the phosphate-sugar molecule forms the backbone of the DNA molecule.
Thus, option-E is the correct answer
<u>Answer:</u>
Q: Which skeletal system <u>disorder</u> might she be suffering from?
A: <u>Osteoporosis</u>
Q: What <u>techniques</u> could be used to diagnose her condition?
A: <u>Bone mineral density (BMD) test</u> or <u>dual energy X-ray absorptiometry (DXA) scan</u>
Q: What treatments are available?
A: Medication, healthy food.
<u>Explanation:</u>
<u>The vertebral discs between vertebrae could shrink with age</u>. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to <u>osteoporosis</u>.
A <u>bone mineral density test</u>, also known as <u>dual energy X-ray absorptiometry</u> scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses <u>X-rays</u> to measure the content of calcium and thus strength of bones.
A person who is already suffering from osteoporosis should be treated with <u>medicine</u> right away so that it <u>stops</u> further <u>deterioration of the bones</u> and <u>avoid any future bone fractures</u>. Further, it can be handled by <u>eating a healthy diet</u> and <u>supplements</u> such as <u>vitamins D</u>. In case some of the bones/vertebrae are <u>already fractured</u>, <u>surgical approaches</u> might be necessary.
Answer:
The capsid has three functions: 1) it protects the nucleic acid from digestion by enzymes, 2) contains special sites on its surface that allow the virion to attach to a host cell, and 3) provides proteins that enable the virion to penetrate the host cell membrane and, in some cases, to inject the infectious nucleic
