The mechanism of somatic recombination known as V(D)J recombination only takes place in developing lymphocytes at the beginning of T and B cell maturation. As a result, B cells and T cells, respectively, have a very varied repertoire of antibodies/immunoglobulins and T cell receptors (TCRs).

<h3>What are immunoglobulin genes ?</h3>

Only B cells can make immunoglobulins, which are encoded by the immunoglobulin genes. The two identical heavy chains that make up immunoglobulin molecules are coupled with the two identical light chains, kappa and lambda. There are numerous chromosomal locations where the immunoglobulin genes are found.

  • B-cell immunoglobulin gene rearrangement tests are used to help diagnose non-Hodgkin B-cell lymphomas and evaluate for residual or recurrent disease after treatment. There are many different types of B-cell lymphoma and each has different characteristics, prognoses, and a likely response to therapy

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers, and the other has white, terminal flowers
Savatey [412]

The probability of producing plants with white axial flowers is 1/16.

The given question is based on the law of independent assortment.There are two parents out of which one has red, axial flowers (RY) and the other one has white, terminal flowers (ry).

In F1 generation, all individuals have red, axial flowers which is RrYy which results in the formation of 8 gametes which is 4 from each parent. When these gametes are crossed with each other individually using a punett square, it results in the formation of 16 offspring out of which only one offspring has white terminal flowers.

Thus, the probability of producing plants with white axial flowers is 1/16.

ddd [48]

Answer:

3. D. The red blood cell will shrink from losing water molecules

59. C. Glucose + Oxygen —> Carbon dioxide + Water

Explanation:

The red blood cell has a lower salt concentration than the liquid which means that it has a higher water concentration than the liquid.

By the process of osmosis, water will flow from the red blood cell to the liquid which would lead to the red blood cell shrinking in size.

Cellular respiration is used to create energy for cells. It works by burning glucose in the presence of oxygen. The result is an outburst of energy and CO2 as well as water.

Diet and nutrition are closely linked to the study of biomolecules. how should you monitor your food intake to ensure the cells
alukav5142 [94]

The intake of food must be monitored to make sure that the cells in the body possess the essential nutrients to function. For example, one must consume the balanced diet, which is rich in carbohydrates, proteins, essential macro and micro-nutrients, fewer fats, and others.  

The nutrition and diet are closely associated. The food consumed is digested and conducted to the different segments of the body as an important molecule, that is, in the form of glucose. Thus, the prediction of proteins and glucose in the cells of the body is the suitable procedure to monitor the substances needed for the cells to function.
