Answer:

1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.

2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

The hormone _______________ is released from the pancreas when blood glucose is elevated above a normal range.
Viktor [21]
<span>The hormone INSULIN is released from the pancreas when blood glucose is elevated above a normal range.

This hormone regulates your blood sugar level. When your blood glucose is elevated above a normal range, the insulin is released from the pancreas. It then attaches itself to the cells and signals them to absorb the excess sugar from the blood stream. 

If your blood sugar level is low, insulin signals the release of stored sugar to the blood stream to maintain the normal level of your blood glucose.</span>

Like plants, human beings have similarities and differences. God gave us talents which He wants us to use. What can you do best?
asambeis [7]
Well, humans have talents. Whether those talents are god given is up for debate. I'd argue those talents are a result of millions of years of evolution and natural selection as proven by Charles Darwin, not given by an unproven deity, but I don't know what school year you are in so you may not have escaped the years where religion is forced upon you :P

Anyway, if you're being asked this question, what do <em>you </em>like doing? I'd say my talent lies in science, as I was the top performing physicist throughout my gcse years, and I love the subject. In my opinion what you do best is what you love doing most, as if you have a passion for something it will almost always be your best talent. I can't answer that question for you.

Sharing this talent to others is basically teaching and also spreading your passion for your talent to others. They probably won't ever be as good as you because they will have their own talents and passions, but you can give them an insight into it by teaching them what you know and encouraging them to invest some time into it.
