sergiy2304 [10]

A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.

<h3>What is the difference between photorespiration and respiration?</h3>

One of the basic differences between photorespiration and respiration concerns the effect of O2 on the two processes. Respiration saturates when O2 reaches approximately 2%, while photorespiration does not reach saturation in a pure O2 atmosphere.

<h3>Under what conditions does photorespiration occur?</h3>

Photorespiration is an expensive metabolic pathway that occurs when the Calvin Cycle enzyme rubisco acts on oxygen instead of carbon dioxide.

With this information, we can conclude that A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.

GrogVix [38]

Answer:

Paul has natural active immunity, while Nicholas has artificial active immunity.

Explanation:

Natural active immunity is an immunity that occurs when an individual is exposed to a disease causing organism, gets infected, and also become immune to the disease due to the primary immune response. From the question, Paul has natural active immunity because he had chicken pox before, and the virus that causes chicken pox has interacted with his immune response, hence, making him to develop natural immunity to the disease.

Artificial active immunity is an immunity that an individual acquires when small amount of immunity to a disease is deliberately exposed to his body. Artificial active immunity is usually produced in the form of vaccinations. From the question, Nicholas has artificial active immunity because chicken pox vaccines were intentionally introduced to his body.
