Answer:
Auatmosphere-the gaseous envelope surrounding the earth; the air. Notes: The energy provided by the sun influences global patterns in atmospheric movement by the fact that the sun's energy(which is thermal energy; heat) heats up the air, water, and land which effects the wind in the atmosphere.

Answer:
1. C
2. All cells of your body have the same DNA/genetic information but cell differentiation causes some genes to turn off and some to turn off. The activated genes are coded for which produce proteins and amino acids allowing cells to differentiate. E.g. Neurons and epithelial cell have same genetic information, however the genes coding for neurons in epithelial cells are turned off or deactivated which make them epithelial cells
Keeping constant the number of chromosomes of the species and perform a summary of recombination, through crossing-over
( Swapping – increases the <span>genetic variability )</span>
hope this helps!
D
Only eukaryotic cells have membrane bound organelles. Prokaryotes organelles just float in the cytoplasm.
Theory of natural selection by Charles Darwin explains the moth appearance in England. The theory of genetics describes this as a mere shift of trait due to environmental factors.
<h3><u>Explanation:</u></h3>
Peppered moths are the moths found in England from a long time ago. The environment before the industrial revolution was pure and pollution free, which led to the growth of the white variety of moths as they were able to camouflage better with the bark of the trees from their hunters. The white trait were the parents, and fertilization between the two recessive traits gave rise to the recessive traits only.
But with the industrial revolution, the pollution increased to a huge extent, leading to deposition of smokes and soot on trees bark where white variety of the white moths got easily recognizable. This led to the black moths which now can camouflage better. Thus the nature selected black variety over white variety for better survival, and the white variety reduced dramatically.
