What happens to the amount of light as you go deeper into aquatic system
gavmur [86]

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.

With independent assortment, the ratio of genotypes in the F2 generation of a cross between true-breeding strains (AA bb x aa BB
MariettaO [177]

Answer:

c. Aa Bb

Explanation:

The parents were pure breeding with genotypes AAbb and aaBB. A cross between AAbb and aaBB would produce AaBb genotypes in F1 progeny. Two F1 strains would be crossed to produce F2 progeny. The F2 progeny would have the genotype ratio= 1:2:1:2:4:2:1:2:1.

Out of all the obtained genotypes in the F2 generation, the proportion of "AaBb" genotype was 4/16. Therefore, "4" in the given ratio represents the genotype "AaBb".

Why do you think meteorologists use a cone-shaped area for the hurricane’s path instead of a straight line?
Finger [1]

A hurricane grows in size before it makes landfall, so a cone is a natural choice for a path; the width of the cone grows larger along its length just as the radius of a hurricane grows along its path.
