Answer: Spermatogenesis begins at birth and continues throughout a man's life.
The process in which
haploid spermatozoa develop from germ cells in the seminiferous tubules of the
testis is known as Spermatogenesis. Thus, the process of spermatogenesis start
with mitotic division of the stem cells that is located close to the basement
membrane of the tubules. However, a mature male gametes known as sperm but it
is commonly known as spermatozoa.
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
His work, which was documented and repeatable, contradicted the accepted cell theory, so a change in the theory was required.
Answer:
As resources are depleted, population growth rate slows and eventually stops: This is known as logistic growth. The population size at which growth stops is generally called the carrying capacity (K), which is the number of individuals of a particular population that the environment can support.
