Answer:
Organelles in a cell are essentially the same as organs in an organism. The mitochondria is the powerhouse of the cell, as we all know. It creates ATP, which is what gives the cell energy. This is similar to how we consume food and create energy from it. Cell membranes are similar to skin, as they keep needed things in, and unwanted things out. Our cells need water too, as it helps create the cytoplasm. We need water to keep us alive and well, as it helps to create many of our needed bodily fluids, and rid us of toxins.

This is because the Crossing over during meiosis cause is a homologous chromosomes to exchange alleles resulting in new combos of alleles in the offspring. Crossing over occurs between prophase 1 and metaphase 1 and is the process where homologous pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. It can also happen during mitotic division, which may result in loss of heterozygosity.
Nitrification. The conversion of ammonium to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria. In the primary stage of nitrification, the oxidation of ammonium ( NH+4) is performed by bacteria such as the Nitrosomonas species, which converts ammonia to nitrites ( NO−2).
Arterial blood pressure is the volume of the blood entering the arteries, or veins. It's controlled by the kidney and when there's too much liquid, it rises, and when there's too little liquid, it drops. Sorry if this doesn't help, but I hope it does.
