Answer:
A. Enzymes function best at a specific temperature.
Explanation:
One of the factors that determinate the enzyme activity is temperature. Each enzyme has a temperature optimum (the temperature at which its activity is the highest) and it corresponds to the normal body temperature for humans (around 98.6 degrees Fahrenheit or 37 degrees Celsius). Some of them can work on lower temperatures while some of them can increase their activity with the increase in temperature. But, since enzymes are usually proteins, high temperature (above 40 degrees Celsius) might denature them and consequently enzymes lose their activity.
I believe the answer is 2: multiple ecosystems in a biome
Puberty phase or the getting old phase
The answer would be the first one because yes, the sun, moon, and earth are all in alignment, meaning all the gravity from the sun and moon will pull the oceans more, making it more high or more low idk where im going with this but yeah the answer is the first one XD
