Answer:

Increases

Explanation:

Biomagnification refers to a phenomenon in which the harmful toxic chemical gest magnified or amplified or increases in the food chain trophic level.

The biomagnification is caused by the bio-accumulation of the toxic material in the organisms.

The harmful toxic chemical enters the food chain through eating like when the crops are sprayed with pesticides and insecticides runoff in the water. From there the toxic material enters the aquatic food chain like from the planktons to fish and then to vultures.

The organisms at higher trophic level die because of the accumulation of the infected lower trophic organisms.

Thus, Increases is the correct answer.

Pavlova-9 [17]

Answer:

The rat will most likely take more of the licorice flavored water

Explanation:

The rat will take more keen on taking more of the licorice flavored water than green water because it has associated the taste of the green water with painful pinch it received on the tail, causing it to refrain the next time it has a choice.

In behavioral psychology, animals are known to tie their actions to either pleasurable or painful feelings. Naturally, the behavior of every animal is conditioned in such a way that it seeks pleasure and avoids pain.

Once the rat begins to associate the taste or sight of the green water with pain, it abstains.

A constant used in an equation for gravity is 0.0000000000667. What is theis represented as a number in proper scientific notati
xxTIMURxx [149]

The correct answer is - C) 667 x 10-13.

The constant that is used in the equation for gravity, or rather gravitational pull, is 0.0000000000667. This same number, in proper scientific notation goes in the shape of 667 x 10-13.

The reason for that is very simple. Any number multiplied with 10-13 will give the exact same number, but as the last part of 13 decimal number. The -13 part dictates the number of decimals. So in the case of 0.0000000000667, the last part 667 is the number that is multiplied, but because the multiplying is in minus, the number goes on the back of the number. Since it has three numbers in it, ten zeros are added in front of it, in order to get the 13 decimals.
