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:
Malaria is a protist disease spread by mosquitos the protist who causes Malaria is called the Plasmodium parasite. Another disease is sleeping sickness spread by the tsetse fly the protist is caused by Trypanosoma brucei
Explanation:
The answer to this statement is true. It is because the size
the total amount of the DNA that it contains makes up the size of the genome.
Therefore, the size of the genome determines the information that it contains
such as the DNA.
The DNA has to code for a protein and it has to replicate
