evolved to minimize its occurrence.

Photorespiration limits casualty products of light reactions that build up in the absence of the Calvin cycle. In many plants, photorespiration is a problem because on a hot, dry day it can drain as much as 50% of the carbon fixed by the Calvin cycle.  The closing of stomata reduces access to CO2 and causes O2 to build up. These conditions favor a seemingly not useful process called photorespiration.  In most plants (C3 plants), initial fixation of CO2, via rubisco, forms a three-carbon compound.  In photorespiration, rubisco adds O2 instead of CO2 in the Calvin cycle. Photorespiration eats up O2 and organic fuel and releases CO2 without producing ATP or sugar. Photorespiration can evolve relic because rubisco first evolved at a time when the atmosphere had far less O2 and more CO2.

After an investigation, Kuri determines that her hypothesis was wrong. What is the best thing for Kuri to do next?
Artist 52 [7]

Write a new hypothesis and conduct new experiments to explore the matter. Thus, option "B" is correct.

<h3 /><h3>What is the Hypothesis?</h3>

Hypothesis

The formulation of hypotheses is one of the key steps in the scientific method.

Hypotheses are usually tested using experiments and are usually accepted or rejected depending on the outcome of the experiments.

If a hypothesis is rejected, it does not mean that the entire subject is abandoned. Rather, new hypotheses may be formed and experiments conducted to further explore the subject.

ser-zykov [4K]

Answer:

As one goes up the other does as well for the first 2 but they aren't proportional (it is not simple cause and effect as there is a lot of factors)

The last question is to decrease their emissions as rising temperature is being effected by rising CO2 levels and rising temperature can cause a feedback loop causing more rising temperature
