Answer:
<u>ion channels</u>
Explanation:
The plasma membrane plays a critical role in regulating and maintaining ionic potential inside the cell, relative to ionic concentration present outside the cell. The ion channels are specific, in that they only recognize and allow particular ions to pass through and block the rest. Their opening and closing depends on the ionic potential during that time period.
Answer: It releases oxygen and heat. The answer is C
Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen you get a flame. Matter does not go when something is set on fire. Matter is always the same. Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).
It is a part of the cell cycle.
Answer:
B. gelisols
Explanation:
tundra soils are formed at high latitudes
By common logic you know that water has pH=7
When you add water to something that is acidic, for example you add water to vinegar, you make it less acidic. So the pH from 2 will be higher for instance 3 or 4 or 5 etc.
This happens because pH=-log[H3O+]
