Answer:
the law of conservation of energy states that energy can not be created or destryed, it can only be transferred between forms. With regards to the total energy in a system, it remans constant as energy can not be created or destroyed.
Explanation:
The pressure inside your lungs and the pressure outside them fluctuate as you breathe. An illustration of a pressure gradient is this.
<h3>What is an example of pressure gradient?</h3>
- The pressure gradient is the amount by which the atmospheric pressure drops in a location at a particular time.
- A pressure gradient is demonstrated by gale-force winds in one city changing to a moderate breeze after an hour. the rate of the pressure in space decreasing (gradient) at a specific period.
<h3>How does pulmonary ventilation change with pressure gradient?</h3>
Thoracic ventilation Because air moves down a pressure gradient, or from an area of greater pressure to an area of lower pressure, the difference in pressures is what drives pulmonary ventilation.
When breathing in and out, the respiratory airways restrict the flow of air. The air must be transported by the pressure gradient from the mount (or nose) to the pulmonary alveoli.

We are living in the quaternary period
Answer:
A)
Explanation:
In the small intestine where the Absorption of nutrients takes place, the enzyme lipase hydrolyses lipid into fatty acid and glycerol
<span> </span>A high metabolic
rate means that the cells in the tissue will needs a high rate of gas exchange
as the cells will be producing a high amount of CO2 during production of energy. The dense network of capillaries ensure that
the cells are adequately provided with oxygen.
