Answer:
B. From 200 m to the surface
Explanation:
Photosynthesis is a process which is light-dependent. Therefore, regions where light availability is not sufficient or event absent will not support photosynthesis.
In the oceans, light availability decreases with increasing depth. Below, a certain depth in the ocean, light availability becomes insufficient to support photosynthesis and this is usually below 200 m. The uppermost region of the ocean from 200 m to the surface of the ocean is sufficiently illuminated to permit photosynthesis by phytoplankton and plants. This region is called the euphotic zone.
Therefore, from the attached image, the correct option is B, since it represents the euphotic zone of the ocean.

"Oxidation occurs when oxygen molecules in the air react with enzymes
in an apple slice, making the apple turn brown, as commonly seen."
Answer:
The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the ..
