Answer:
differentiated; on; off
Explanation:
As the zygote goes through mitosis and creates more cells. Each cell is called a stem cell. In order to become a certain type of cell, these cells will become <u>differentiated </u>Or This means they will turn Genes <u>on </u>for the type of cell they are becoming, and turn Genes <u>off</u> for the type of cell they won't be.
Stem cells become specialized cells through the process of differentiation. The stem cells all have identical DNA in them. They become specialized for a particular function (s) through the process of differentiation. During this process, some <u>specific genes are either turned on or off</u>. <em>Cells in which the same genes are expressed become specialized for similar functions and can then come together to form a tissue.</em>

Answer:
Science can not solve all of our problems. While scientific understanding can help battle things like disease, hunger, and poverty when applied properly, it does not do so completely and automatically. Furthermore, there are many areas of life where science can have little impact.
Answer:
<em>Too much water accumulation leads to a condition called as water intoxication.</em>
Explanation:
Drinking too much water leads to a condition called water intoxication or water poisoning. This happens because the concentration of water becomes such abundant in a person's body that it dilutes the concentration of electrolytes like sodium in the blood. This causes a disruption in the functioning of the brain hence leading to the death of the person. Various such scenarios have been observed in athletes drinking too much water.
Gray matter consists of the <u>unmyelinated axons</u> of neurons.
<u>Explanation:</u>
The outer layer of the brain consists of the grey matter and white matter. The grey matter gets its name by the pinkish grey colour obtained by the greyish colour of the neurons and the red colour from the capillaries.
The grey matter consists of the dentrites, axons and cell bodies and this is essential for memory, attention and learning.
The unmyelinated axons are not covered by the fat protein myelin and these axons carry signals.They are the ones to help the processing of information in the brain.
