<span>When the surface area to volume ratio of a cell decreases, the amount of area available to pass material to the cell increases. This is because the surface area is now bigger in proportion to the volume. The inverse is true - when volume increases more rapidly than surface area, the area available to pass materials through it to the cell decreases.</span>
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells. These develop into mature spermatozoa, also known as sperm cells. (1) Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa.(2)Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis, of which the female equivalent is oogenesis. In mammals it occurs in the seminiferous tubules of the male testes in a step-wise fashion. Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction.
Answer:
The nucleus houses the genetic material of the cell: DNA. DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes. hope this helped!

Question:
How is earth’s motion related to the origin of the galaxy and it’s solar system?
Answer:
<u>The Earth is a part of the galaxy and its solar system and as Earth was created with the big bang, it happened inside of them.</u>
Explanation:
The relative motion of the Earth around the solar system is the Earth is moving and spinning around at a tilt. Our solar system in the galaxy is moving and the galaxy in the universe is constantly moving. They are all moving around a a central object just as the Earth revolves around the Sun.
