Answer:
- Dehydration characterized by a loss of greater than <u>1% to 2% </u>body weight will have a significant impact on muscular strength and anaerobic function.
Explanation:
The integumentary organ of the human body consists of small pores like structures which are responsible for excreting the extra water molecules present in side the body (<em>the function occurs upon the body's request or command</em>). When there is a high temperature inside the cellular and as whole on body level, the water molecules are required to be extracted from the body in order to get the required level of stability, but it is healthy up to a certain level.Just because along water molecules there are also some minerals and salts which are extracted along with water. And if due to some excessive exercise or any other form of high temperature which will effect the body's homeostasis will results in the dehydration(By means of excessive loss of water and minerals from the body).
- <u>Unavailability of sufficient water required for a healthy lifestyle:</u>
If a person is facing some scarcity of water and mineral resources, while at the same time there is a increase in temperature then only dehydration will occur causing loss of 2% wight of normal being in severe conditions of dehydration.
Answer:
Gravity is a force that combines all the particles of "interstellar cloud" together to form a star.
<u>Explanation:</u>
A star is a "luminous ball of gas" made from the gases of helium and hydrogen and it is held under the action of gravity. Sun is the nearest star present to the earth and the nuclear fusion process is proposed to develop various stars in the galaxy.
Interstellar cloud indicates the combination of various gas, plasma, dust in the galaxy. This cloud contains 16 hydrogen atoms for every helium atom and also contains traces of carbon, iron and nitrogen atoms.
Gravitational force compresses the interstellar cloud and triggers them to result in a star.
