Answer:
Amount of air inhaled or exhaled per breathing stroke is called as tidal volume. Tidal volume is 400 ml for women while for men it is 500 ml.
Explanation:
In respiration, tidal volume is defined as the volume of air that a person inhales or exhales in one stroke of normal breathing.
The tidal volume varies in adult men and women. In resting condition, tidal volume is 400 ml for women while for men it is 500 ml.
This tidal volume varies with the requirement of the body. During intense physical exercise the amount of gas intake increases in order to full fill the requirement of body and hence the tidal volume increases.

"Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cell. Could you explain that observation?
"
Answer:
You are visualizing the onion cell during mitosis interphase. At that time, cells may have multiple nuclei and some of them may not be visible near the cell wall.
Explanation:
Experiments with onion roots are common when we want to visualize the phases of the cell cycle or to visualize chromosomes and cell nuclei.
If after the experiment with an onion cell you are unable to visualize the cell nuclei near the cell wall, it means that you are visualizing the cells during the interphase of mitosis. At that time, cells may have multiple nuclei and some of them may not be seen near the cell wall.
Answer:
<u>Changes in inheritable physical or behavioural traits</u> due to changes caused by variations as the organism move from one generation to another.
In addition changes in selective pressures of their new environments in order to gain adaptions for survival in the new environment is another factor for this changes.
Explanation:
Answer:
Air is forced to rise over mountains, air cools and condensation occurs, rain falls over the mountains, dry air sinks down the other side of the mountain. Some deserts form in areas that lie at great distances from the sea. The air here is much drier than on the coast.
