<span>The answer is molecular clocks.
Molecular clocks use rates of mutation to measure evolutionary time. This technique is based on the fact that mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages and vice versa.</span>
Answer:
Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.
For most enzymes to operate in the body, the optimal temperature is 37 degree Celsius or 98 degrees Fahrenheit. Most of the human enzymes have a maximal activity at pH around 7.2, which is the pH of most body fluids. However, there are exceptions such as, pepsin.
During summertime in the Northern Hemisphere, Earth is tilted so that the Northern Hemisphere is angled more directly at the sun. It receives more direct sunlight and is warmer.
