How does fruit react to oxygen?

Answers

Answer 1
Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction). Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction.

What type of movement is running? A. Locomotive B. Ballistic C. Static D. Fine Twitch

Answers

From what I know its B

Running is a locomotive movement in which the body is moved in one direction or a combination of directions from one point to another. The option A is correct.

Walking, running, jumping, hopping, crawling, marching, climbing, galloping, sliding, leaping,  and skipping are the primary locomotor skills.

Static movement , which refers to staying in one place, running requires the body to actively engage its muscles to generate the force necessary for forward motion.

A ballistic movement is a form of movement that involves a rapid and strong contraction of muscles, which frequently results in a projectile-like motion.

A fine twitch is a type of muscle fiber contraction, not a movement.

Thus, the correct option is A.
