<span>The answer is gravity.  According to general relativity by Einstein, the bending of space-time is dependent on the nature of the matter of the object, or energy, momentum, and radiation. The heavier the object, the bigger the curvature of space-time it causes, that is felt as gravity. Heavier objects with a bigger gravity pull, pull other objects (with lesser gravity pull) more towards them than vice versa. </span>

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.

Explain why excess nitrogen in the water can lead to fewer fish and shrimp
Kaylis [27]

Answer:

Excess nitrogen can cause over-stimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters. So few organisms live in these conditions or even can suffocate and die.

Micah has straight hair. If he is homozygous for the gene that determines straight hair, what is true of his parents?
alexgriva [62]

Answer:

They have contributed same allele for straight hair.

Explanation:

There are two conditions homozygous and heterozygous. In homozygous conditions both the allele of a particular gene is same in an offspring which means the offspring got two same alleles from its parent for a particular gene and if an offspring is heterozygous for a gene that suggests that the parent has contributed two different alleles for that gene in the offspring.

So If Micah is homozygous for straight hair then it can be concluded that his parents have contributed two same alleles for straight hair genes.
