Part 1;
Because there is only limited amounts of fresh water on the Earth the rest is salt water; which humans can not survive on as the salt dehydrates our bodies instead of hydrates.
1) The more we try to get the the fresh water the more we will likely make more pollution.
2) The more we use the less there is.
3) Everything needs water.
Part 2; no idea I believe it is the ice caps, as it is fresh water in the ice caps and not a lot of humans up there to pollute the runoff.
Answer: Prophase
Explanation: Prophase, is the first and longest phase of mitosis. First, chromtain condense it into chromosomes and the nuclear membrane breaks it down.
Step 1: Copy of one side of DNA strand is made (called mRNA, messenger RNA)
step 2: mRNA moves to cytoplasm, then ribosome
step 3: mRNA goes through ribosome 3 bases at a time
step 4: transfer RNA (tRNA) matches up with the open DNA bases
step 5: tRNA releases the amino acid at the top, which joins the chain of amino acids being produced
Homoeostasis is a system of maintaining balance. This is important because too much salt and the body can develop problems like high blood pressure, and edema. This increases the risk of a heart attack, strokes, dementia, and kidney disease. Then the dissolved carbon is unnecessary to the body.
