Chromosomes come from genes. All females produce eggs with an X chromosome, and sperm that fertilizes it will have either an X chromosome or a Y chromosome.
Pumping is a factor that could account for a drop in the water table.
Explanation:
When manufacturers , farmers as well as residents continuously pump water at a rate of thousand gallons per minute the water table will experience a drop. It leads to an unnatural depletion of the unground reserved water.
Groundwater plays an important role when a land suffers due to drought. Groundwater is used for irrigation purposes as well as groundwater acts as an underground aquifer. Excession use of groundwater leads to its depletion and thus the water table also falls.

Answer:
Actually, in physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the universe, shortly after the Big Bang. About first millisecond, the universe had cooled to a few trillion kelvins (1012 K) and quarks finally had the opportunity to bind together into free protons and neutrons. Free neutrons are unstable with a half-life of about ten minutes (614.8 s) and formed in much smaller numbers. The abundance ratio was about seven protons for every neutron. Before one neutron half-life passed nearly every neutron had paired up with a proton, and nearly every one of these pairs had paired up to form helium. By this time the universe had cooled to a few billion kelvins (109 K) and the rate of nucleosynthesis had slowed down significantly.
Explanation:
False
Proteins are polymers of molecules called amino acids, some contain thousands. Lipids are formed when a glycerol molecule combines with compounds called fatty acids, therefore they are not polymers because they contain one molecule and are not macromolecules. Hope this helps! :)
