The answer is The G1 phase, or Gap 1 phase, is the first of four phases of the cell
cycle that takes place in Eukaryotic cell division. In this part of
interphase, the cell synthesizes mRNA and proteins in preparation for
subsequent steps leading to mitosis. G1 phase ends when the cell moves
into the S phase of Interphase.

Answer:
When a neuron fires and its electric charge travels down the axon, causing neurotransmitters to be released by the neuron's terminal buttons, an <u>action potential</u> occurs.
Explanation:
An action potential, commonly termed as impulse, can be described as messages which are transferred in electrical form. Action potential are caused due to different electric charges. An action potential is generated by a stimulus which causes transfer of sodium ions into the axons resulting in depolarization of the neuron. To overcome this, potassium ion will enter the cell and an action potential will be generated.
The action potential causes release of the neurotransmitters so that signal messages could be transferred.

What is y
Answer.
ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries.
Explanation
. This option is the mechanisms of regulation of osmoregulatory balance in urine production by the kidney
ADH responds to high solute potential of the blood(high osmolarity) by stimulating the opening of transmembrane proteins AQUAPORINS in the walls of the distal and collecting tubules
This promotes influx of Solutes from the passing tubules into the peritubular capillaries.Water follows by osmosis(reabsorption),untill the osmolarity of these fluids drops.
As this occurs the hypothalamus stopped the production of ADH, the aquaporins closes up,solute influx into peritubular capillaries stoped and therefore water influx
This is negative feedback Mechanism.it is an example of homeostatic process of maintaining water balance of the body during urine formation .
Explanation:
A negative tropism is when a plant grows away from stimulus
Answer:
Weight and skin color.
You can be born with a different skin color and it can change according to the place you live in. Suppose you were born in Alaska and moved to Mexico, your skin color would become darker as you will receive more vitamin D. You body structure to will also be based on your parents. If your parents are fat but you exercise and eat healthy your body structure will change.
