Explanation:
a hierarchical series of organisms each dependent on the next as a source of food.The series of processes by which food is grown or produced, sold, and eventually consumed.
Yeasts will grow over a temperature range of 10°-37°C (50°-98.6°F), with an optimal temperature range of 30°-37°C (86°-98.6°F), depending on the type of species. There is little activity in the range of 0°-10°C. Above 37°C yeast cells become stressed and will not divide properly. Most yeast cells die above 50°C (122°F).
In the presence of an enzyme, the Activation energy is lowered. thus the reactions reaches the activation energy and the reaction is initiated faster and therefore completes faster than the reactions without enzymes. Enzymes lower activation energy, which allows a reaction to occur at a faster rate.

Answer:
B and D
Explanation:
Since it says all carbon atoms have six electrons, we know that they only have six protons too. The carbon 13 and 14 means they have extra neutrons that increases their atomic mass.
