Answer:

Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.

Which statement is a well-written hypothesis about DDT and its effects on the environment?
Ray Of Light [21]

The statement that is a well-written hypothesis about DDT and its effects on the environment is as follows: If DDT levels in the environment increase, then the number of predatory birds will decrease (option B).

<h3>What is an hypothesis?</h3>

Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation or experimentation.

Hypothesis is widely regarded as an educated guess because it predicts the outcome of an experiment and can be tested to either be true or false.

A hypothesis is usually written as an IF, THEN statement.

Therefore, the statement that is a well-written hypothesis about DDT and its effects on the environment is as follows: If DDT levels in the environment increase, then the number of predatory birds will decrease.

Unlike freshwater fish, saltwater fish
Olin [163]


The best answer is A

Saltwater fish are hypotonic to their surroundings. This means their blood has a higher water concentration than the surrounding sea water.

Due to the fact that there is more salt and less water outside their bodies, there is a tendency to take in salt and lose water.

To counter this, salt water fish drink a lot of the sea water and urinate very little. Special cells in the gills actively eliminate salt at the cost of extra energy and these fishes do not absorb any salt from the water they drink.
