The catalase worked best at 37 °C because the temperature is optimal.
<h3>Enzyme and temperature</h3>
Enzymes are proteinous substances that are capable of speeding up the rate of biological reactions.
However, enzymes are very specific in actions and work best at a specific temperature range.
Below the temperature range, the activities of enzymes reduce and may even become denatured.

Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
Answer:
This convection produces winds and ocean currents.
<u>Answer:</u>
<em>Repeated use of chemical fertilizers has several adverse impacts.
</em>
<u>Explanation:</u>
<em>Chemical fertilizers are used to increase crop yield and raise agricultural productivity.</em> But a land loses its fertility over the years due to repeated fertilizer use.
<em>Excess use of fertiliser makes the soil acidicby reducing the organic content of the soil. </em>
When the amount of chemical fertilizers containing nitrogen is applied is beyond the amount that can be absorbed by the plants, it results in the release of greenhouse gases into the atmosphere.
<em>When the fertilizers are washed into water bodies their nutrient content increases heavily and this depletes the oxygen in water.
