Sexual reproduction results diversity
Light bends when it hits water so it can only travel so far. So the deeper you go the less light there will be.
Explanation:
The ocean is broken into three zones based on intensity and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone. This zone includes the vast preponderance of commercial fisheries and is home to many preserved marine mammals and sea turtles.Only a small amount of light penetrates behind this depth.The zone between 200 meters (656 feet) and 1,000 meters (3,280 feet) is usually regarded to as the “Twilight” zone, but is authorized the dysphotic zone. In this zone, the intensity of light rapidly consumes as depth increases. Such a miniscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no eternal possible.The aphotic, or “midnight,” zone survives in depths below 1,000 meters (3,280 feet). Sunlight does not perceive to these depths and the zone is immersed in darkness.
Keystone predators can maintain species diversity in a community if they prey on the community's dominant species
Option B is correct.
What is meant by keystone predator?
A keystone species is usually a dominant predator whose removal allows a prey population to explode and often decreases overall diversity. other forms of keystone species are those, like coral or beavers, that significantly alter the habitat around them and thus affect large numbers of other organisms.
Are keystone species always predators?
A keystone species is usually , but not always, a predator. Just some predators can control the distribution and population of large numbers of prey species. the whole concept of keystone species was founded on research surrounding the influence of a marine predator on its environment.

So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck.
Answer:The Doppler radar used in weather forecasting measures the direction and speed, or velocity, of objects such as drops of precipitation. This is called the Doppler Effect and is used to determine whether movement in the atmosphere is horizontally toward or away from the radar, which aides in weather forecasting.
