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 killer whales would die of starvation as they would have no source of food, and the cod would become overpopulated. The krill would be scarce, and the algae would over grow.

Answer:
Changes in temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators can affect enzyme activity.
For example increasing substrate concentration increases the rate of reaction.
Explanation:
This is because more substrate molecules will be colliding with enzyme molecules, so more product will be formed.
