When plants are stressed by dry conditions, they secrete the hormone abscisic acid (ABA) and in response the stomata close, even
dimaraw [331]

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.

Brown spotting of the teeth in humans is caused by a dominant X-linked gene. If a man with normal teeth marries a woman with bro
nata0808 [166]

Answer:

25%

Explanation:

The female with brown teeth had a father with normal teeth. Since normal teeth is a recessive trait, the father would have been homozygous recessive for the trait and would have transmitted one recessive allele to the female. Therefore, the female is heterozygous dominant for brown teeth.

Let's assume that the allele for brown teeth is X^B while the one for normal teeth is X^b. The genotype of heterozygous dominant female would be X^BX^b and that of the male with normal teeth would be X^bY.

A cross between X^BX^b and X^bY gives progeny in following phenotype ratio= 1/4 daughter with brown teeth: 1/4 daughter with normal teeth: 1/4 son with brown teeth: 1/4 son with normal teeth. Therefore, the probability of having a daughter with brown teeth is = 25%

Cytosine makes up 24% of the nucleotides in a sample of DNA from an organism.
Alchen [17]

Answer:

26%

Explanation:

if cytosine makes up 24%, then guanine also makes up 24%.

add these to get 48%.

subtract that from 100% to get a remaining 52%

then split the 52% between adenine and thymine to tell you that 26% is thymine
