One gene comes from each parent for every trait. Each trait is passed from generation to generation. When gametes are formed, genes separate. If there are two unlike genes, one may be seen while the other is hidden. The inheritance of each trait is determined by units or factors that are passed on to descendants unchanged, and individual inherits one such unit from each parent for each trait, a trait may not show up in an individual but can still be passed on to the next generation and also the genes for each trait segragate themselves during gamete production.
Answer:
Mutation plays a vital part in evolution; it is the greatest source of genetic variation. In evolution, it creates a new DNA sequence for a particular gene, creating a new allele. Additionally, recombination can produce a DNA sequence (a new allele) for a specific gene through intragenic recombination.

Hope this helps!
The correct answer is: stratosphere.
This is because their temperatures are rising instead of decreasing.
There are 4 primary layers of the atmosphere on Earth:
Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.
Stratosphere (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.
Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer
Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.
For this item, I would go with letter "D. physical destruction of marine habitats". Many of the modern ways of fishing poses an irreversible destruction to marine habitats. These practices include trawling, lining methods, purse seining, etc.
