Answer:
C. K+ ions flow out the the guard cells and water flows out the cells.
Explanation:
The turgidity of the guard cells allows the opening and closing of the stomata. This is especially necessary when it comes to water conservation in plants. In order for the cells to become turgid or flaccid, there must be the influx and out ward movement of water via osmosis.
In order for this the occur the osmotic pressure of the cellular environment must change and this is done by changing the solute concentration.
The pumping in of K+ ions out the cell allows the solute concentration to decrease and this in turn encourages the movement of water across a concentration gradient through a semi-permiable membrane.
The water leaves the guard cells and they become flaccid. This causes the stomata to be covered.
The right answer is B. cookie.
Sucrose, or sucrose, is a sugar derived from sugar beet or sugar cane. It is also known as table sugar (used in cooking and baking). Comprised of fructose and glucose, sucrose is known for its sweet and sweet taste particularly appreciated. However, and despite the pleasure it provokes, sucrose consumed in excess would represent a major danger to health.
Answer:
Water is important in chemical weathering because most substances dissolve in water.
The process of dissolving breaks up the minerals in the rock into small pieces. The small pieces mix with water to form.
Acids are also agents of chemical weathering and cause more chemical weathering than pure water does.
