Answer:
The correct answer will be option-B
Explanation:
Meiosis is a way of cell division used by the organism to produce a large number of cells from a few parent cells. This is used to make the gametes of the body.
Meiosis produces four daughter cells from a single parent cell in two stages that is meiosis I and II. Each stage proceeds in four phases- prophase, metaphase, anaphase and telophase.
The reduction division of the chromosomes or the ploidy number takes place during anaphase I of meiosis I and not prophase I which is the initial phase of the division. Therefore, during prophase I the chromosome number of the cell remains the same.
Thus, Option-B is the correct answer.
Answer: Decrease
It will decrees because required volume of blood will not be emptied into the pulmonary circulation to reach the lung for oxygenation. Rather blood flows back into the Right atrium ,(regurgitation,) through the these valves during ventricular contraction ( systole)of the Right Ventricle instead to the pulmonary circulation which reduces blood flow leading to volume overload in the heart. Eventually this affects systemic circulation,

Answer:
pituilatry gland
Explanation:
The pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain.
Answer:
RFLP analysis of genomic DNA is facilitated by Southern blot analysis. After electro-phoresis, DNA fragments in the gel are denatured by soaking in an alkali solution. This causes double-stranded fragments to be converted into single-stranded form (no longer base-paired in a double helix). A replica of the electrophoretic pattern of DNA fragments in the gel is made by transferring (blotting) them to a sheet of nitrocellulose or nylon membrane. This is done by placing the membrane on the gel after electro-phoresis and transferring DNA fragments to the membrane by capillary action or electro-transfer. DNA, which is not visible, becomes permanently adsorbed to the membrane, that can then be manipulated easier than gels.
