A. an ecosystem comprises a community and the abiotic environment.
The same number of chromosomes as normal cells. Meiosis is the method our body uses to replenish body cells, called somatic cells which are diploid cells, meaning that they have two sets of chromosomes. The only other type of cells in our body with differing numbers of chromosomes are gametes, which are sex cells. These cells are haploid cells meaning they have half the amount of normal chromosomes, so when an egg and sperm fuse you get the normal amount of chromosomes for body cells. Hopefully this helped!
I believe the answer is choice D. Hope this helps!!!

The answer is C. High birth rates
High birth rates or overpopulation is one of the most pressing environmental issues today. It silently is the largest contributor to environmental pollution, global warming, loss of habitat for animals as the wild is converted to cities and housing. INtensive farming practices to increase food supply also aggravates the situation. Moreover, the consumption of natural resources and the slow reaction to preserve it endangers life existence.
Explanation:
1. A decrease in the number of greenhouse gases that humans produce will result in lowered global temperatures. This will allow the ice sheets in the polar regions to increase increasing also albedo.
2. Using light-colored building materials on houses and pavement in urban centers will work towards increasing albedo as more sunlight is refelcted back by built environments.
3. Decreased deforestation/increase in aforestation increases the earth’s sirface albedo because vegetation reflects back more sunlight than the earth’s bare surface.
