Explanation:
The rate of photosynthesis increases withe increase in temperature. Photosynthesis like any other chemical reaction responds positively to an increase in temperature.
At high temperatures, enzymes that takes part in the photosynthesis can be destroyed. This is 20°C where enzymes are usually denatured.
- Photosynthesis is the process where green plants manufacture their food using inorganic substances from the environment.
- During photosynthesis, plants combines carbon dioxide with water and produces organic molecules and oxygen.
- Like any other chemical reaction, the reaction will proceed faster with an increase in temperature.
Hypothesis: If temperature is increased then the rate of evolution of oxygen gas increases because the rate of chemical reactions increases with increase in temperature.
Since oxygen is a by product of photosynthesis, we can quantify its rate of production as temperature increases.

I will answer the question accordingly so that it help you under stand it better.
Question A.
During an extreme heat wave, plants with white flowers survive better.
What mechanism is in work here?
Answer: Mechanism of Natural Selection
will work here. This is called survival of the fittest which means the best color which fits in harsh conditions will dominate over others and will survive for longer time.
What is the effect on the gene pool?
Answer: The Frequency of white allele will increases
because white color is the best fit to extreme heat wave.
Question B.
A person uproots the five closest plants, which all happen to have white flowers.
What mechanism is in work here?
Answer: The mechanism of gene flow will work here as color of flower represents genotype of flower.
What is the effect on the gene pool?
Answer: The Frequency of white allele will increases because genotype of white flowers is increased.
The 4 organ systems that are used when running:

2.) Muscular system
3.) Skeletal system
4.) Nervous system
