Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: <u>inhaling and exhaling.</u>
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
The chromosome must be duplicated before mitosis.
Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. This process first requires the parent call to duplicate all of its genetic material. This ensures that the daughters cells are genetically identical to the parent cell and also the other daughter cell.
This is important because mitosis is used in many cases in living things such as growth, repair, and more. This ensures us for example not suddenly changed to another organism or another characteristic.
A control variable is a scientific experiment in which the experimental element is unchanged throughout the experiment
a control group is a group in an experiment that does not receive the treatment by the researchers (untouched by them) and used to see the changes between the controlled group and that of the group that received the vial
