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.
Answer:
Hyaline Membrane Disease
Explanation:
Hyaline Membrane Disease or the respiratory distress syndrome is a disease caused in newborn babies especially in premature infants due to the absence of the biological surfactant.
A glassy membrane composed of the dead cells and the protein is formed and lines the tiny sacs called alveoli which decreases the volume of the alveoli and difficulty in the exchange of gases in the infants.
Thus, Hyaline Membrane Disease is the correct answer.
If CPR is not performed, C. 4 minutes will elapse before the brain becomes damaged from lack of oxygen.
One minute isn't enough time - you can even hold your breath for one minute without fainting. Some people can even do it for 2 minutes.
Ten minutes is too long - you would be long dead.
Yes. They do it to escape the winter. Hope it helps.
The answer is mitochondria because mitochondria is involved in cellular respiration.
