<span>In humans, oogenesis
in comparison to spermatogenesis is different in that the temperature they have.
Female puberty typically occurs much later than the age of male puberty oocyte
production works best at cooler temperatures than those that support
spermatogenesis oogenesis continues throughout life, but spermatogenesis
typically ends.</span>
1.) It is True that when a cell is put into an isotonic solution, individual water molecules cannot move back and forth across the cell membrane.
2) It is False that a when a cell is put into a hypertonic solution, there is a net movement of water molecules across the cell membrane into the cell.
3) It is True that when a cell is out into a hypotonic solution, there is net movement.
4) It is False that the movement of any solvent across a semi-permeable membrane is called osmosis.
Answer:
Option A, B, C
Explanation:
A wave’s highest part is called crest and the lowest part is called trough. The vertical length between the highest and lowest part of wave i.e crest and trough is called wave height. Hence option A is correct. Steepness of waves is defined as the ratio of height of wave to its length i.e wavelength. Hence option b is correct
And the steepness of wave should never exceed the ratio of 
, if ration exceeds the wave gets steep and finally breaks down
Hence, Option A, B, C are correct
Answer: It is an example of TRISOMY 21.
Explanation:
Trisomy 21 is a genetic condition in which 21 chromosome fail to separate during the growth of egg cell and sperm which make either of the two to an extra copy of chromosome 21. This is also known as down syndrome. This lead to slow and in appropriate mental development in affected individual.
Phosphoriboglycinamide transformylase(GART) is agene found on chromosome 21, which lead to down syndrome is an example of trisomy 21.
