B
Area B of the graph shows the activation energy required if an enzyme was not present
Explanation:
Reactions with high activation energy cannot occur spontaneously. Enzymes are responsible for lowering this activation energy and enabling reactions to occur at a faster pace than natural. An example is carbonic anhydrase enzyme that enables increased rates of carbon dioxide dissolving in and out of blood plasma.
Enzymes distort the bond of reactants such that they become unstable ( this raises the reactants Gibbs free energy). The bonds therefore break and rearrange to form the products of lower and stable energy states.

Answer:Physical systems differ from social systems because a physical system refers to systems that rely on a group of physical parts to perform a function. Examples of a physical systems are solar systems or even an animals digestive system. Social systems are systems like an ant colony, wolf pack, or a town.
Explanation:
Answer:
Most people were either doing they’re daily jobs and going to school, or traveling.
Explanation:
Answer: 32 chromosomes, they are clones of the parent drone
Explanation:
The production of offspring drones without fertilization means that offspring that are produced are produced by mitosis, which results in daughter cells that are clones of the parent. They have the same amount of chromsomes as the parent drone, which is 32.

Whereas an onion epidermal cell has a cell wall, a human cheek cell does not. Instead, a semi-permeable membrane surrounds the cytoplasm of the cheek cell. While there are chloroplasts present in onion cells, they are absent in cheek cells. </span>
