balandron [24]

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.

Answer:

See the eplanation below, please.

Explanation:

In sickle cell anemia, hemoglobin has the form of rigid bars inside the red blood cells, causing them to adopt sickle shapes being not very flexible. These cells can block blood vessels, stopping the flow, causing oxygen to not reach the tissues.

The cause of this anemia is due to a genetic mutation (there is a substitution of thymine for adenine in the beta globin gene, located on chromosome 11), generating Hemoglobin S with a decrease in oxygen binding.
