Answer:
sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone.

The answer is fertilization.
Among the given choices, fertilization is the closest answer. Generally, fertilization occurs when the nucleus both reproductive cells called gametes from a male and a female combines. And the result of the fertilization is the combination of the chromosomes from the male and the female.
The difference is that eukaryotic has a nucleus prokaryotic doesn't.
In eukaryotics, the mitochondria and chloroplasts perform various metabolic processes and are believed to have been derived from endosymboic bacteria. In prokaryotic similar processes occur across the cell membrane; endosymboints are extremely rare.
The cell walls of prokaryotic are generally formed of a different molecule (peptidoglycan) to those eukaryotics (many eukaryotics do not have a cell wall).
Prokaryotic are usually much smaller than eukaryotic cells.

AP Biology Question:
Scientists are testing substance L to determine how it enters mammalian cells in a culture. The cells maintain a 120 millimolar (mM) intracellular concentration of substance L . The scientists determined the rate of entry of substance L into the cells at various external concentrations of substance L (10 to 100 mM) in culture medium (Table 1).

Peyer's patches (aggregated lymphoid nodules)
Explanation:
Peyer's patches are anatomical regions located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine. These patches are nodules or cumulus of lymphatic tissue and other accessory cells, and this is why they represent a huge part of the mucosa´s immunity system.
Peyer's patches belong to the group of lymphoid tissue associated with the intestine, composed of lymphoid follicles distributed along the gastrointestinal tract.
A lymphoid follicle is a cumulus or aggregate of lymphoid cells that do not have a well-defined structure nor organization. In general, these follicles are isolated from each other in the intestine. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque. The Peyer´s patches are formed principally by lymphocytes B that synthesize immunoglobulin A, which has an important role in immunity.
