Total number of chromosomes remain same in same species of organism through meiosis process. In meiosis process the number of chromosomes are reduced to half as a result in gametes only one set of chromosomes will be present. In this process chromosomes are same.....

What To maintain the chromosome number of an organism the gametes must?
Be produced by meosis.
Why is meiosis necessary after fertilization to maintain chromosome number?
meiosis occour only in sexual cells and its reduce the number of chromosomes so when the sperm cell fuse with ovum cell the number of chromosomes it will be the same as in parents cell. Humans cells have 46 chromosome sperm cells have 23 chromosomes ovoum cells 23 chromosomes when sperm cell fertilize the ovun they fuse their genetic material and we have 23+23=46 every cell in our body it has 46 chromosome except sexual cells
Control of hormone secretions is essential to maintain?
The internal environment
What is a buffer in basic chemistry?
Buffers maintain a constant pH.
What is the genetic theory of aging?
Human cells maintain their own seed of destruction at the chromosome level.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)

Can object at constant speed can maintain constant velocity?
It can, but it won't always. In other words, if the speed is constant, the velocity may, or may not, be constant as well.
How do amphibians maintain a constant internal temperature?
homeostasis
What is the use of buffer?
To maintain constant the pH of a solution.
Why are solutions buffered?
The purpose is to maintain a constant pH.
