Answer:
Gametogenesis is the production of gametes from haploid precursor cells. ... During the process of gametogenesis, a germ cell undergoes meiosis to produce haploid cells that directly develop into gametes.
Explanation:
The mitotic spindle pulls the chromosomes together at the metaphase plate. Microtubules from opposite spindle poles grab the two sister chromatids of each chromosome. In metaphase, the spindle has collected all the chromosomes and lined them up at the middle of the cell, ready to divide.
<h3>
What are chromosomes?</h3>
Chromosomes are the greatest level of DNA and protein organization. Chromosomes' primary job is to transport DNA and genetic information from parents to offspring. During cell division, chromosomes play a vital role. They keep DNA from becoming twisted or damaged.
The metaphase plate is a plane or region that is about equidistant from a dividing cell's two poles.

Answer:
Option D, Gastric Juices
Explanation:
The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.
Hence, gastric juice does not belong to second line of defense.
Thus, option D is correct.
