Biology

Answer:

Water reacting with nitrogen gas

Explanation:

A<em> </em><em>physical change</em><em> occurs when matter changes its form without a change in its chemical identity</em>. A<em> </em><em>chemical change</em><em>, on the other hand, occurs through a chemical reaction, forming new products.</em>

When water evaporation, freezing, and heating produce physical changes in water, therefore the correct answer is "Water reacting with nitrogen gas" because it alludes to a chemical reaction.

I hope you find this information useful and interesting! Good luck!

Macy has hired 400 store sanyas. If each Santa sees 125 children a day for 30 days, how many children are seen by mac's santa
Pachacha [2.7K]
So here let's first find the amount of children every santa, in total, sees in one day. So if there are 400 santas, and each sees 125 children, you can just multiply 400 by 125 to see how many children all the Santas see in one day.

400 * 125 = 50,000

Now, since there are 30 days which all the santas see 50,000 children, you can then multiply 30 by the 50,000 children to get how many children are seen by Macy's Santas in a month.

30 * 50,000 = 1,500,000

So 1,500,000 children are seen by Macy's Santas.

A graded hyperpolarization of a membrane can be induced by _____.
Doss [256]

Explanation:

In biology, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. That is, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in the membrane voltage in which the membrane potential is more clearly positive or negative, are hyperpolarizations.
