Answer:
B. Temperature
Explanation:
The heart rate depends on the temperature so the heart rate is dependant and the one that changes is independant
The stomata and their guard cells allows this happen.
Stomata is like a hole or gap on a leaf, most of them are present in a bottom side of the leaf, since waxy cuticle is not present over there. And 2 guard cells make up a stomata.
Guard cells are able to control the size of the stomata, depending on the situation. For example, the guard cells close up during day time because a lot of sunlight may cause more water loss.
In conclusion, guard cells and the stomata are the main structures that allow carbon dioxide and oxygen (water too) diffuse in and out of leaves.
The main role of chloroplasts<span> is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water</span>
You will run and breathe heavily for a long period of time. is affecting your pH levels, Lowering the pH, making it more acidic.
- A. Lowering the pH, making it more acidic.
<h3>How does respiratory rate affect pH?</h3>
When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.
With this information, we can conclude that By eliminating carbon dioxide during expiration, pulmonary ventilation reduces the acidity of the blood, helping it to maintain the desired alkalinity level.
