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.

Answer: It is important to conduct many different experiments and estimates in a project for having as much statistic data as possible, because it is necessary to show proof on whichever project you are into. In order to avoid confusion, it's also possible to <u>organize data in Excel sheets/tables so it can be visually easier to interpretate</u>. <u>Gut instinct isn't enough to prove something wrong or righ</u>t, and <u>few data means higher probability of things going in ways other than the expected</u>.
<span>Osmosis is defined as the movement of water across a
semipermeable membrane from high concentration to low concentration. This
occurs when the surrounding environment of the cell has a higher water
concentration than the cell itself. Osmosis is important in animal cells
because it helps in the distribution of nutrients and the release of metabolic
waste products. In plant cells, osmosis is responsible for the absorption of
water from the soil and the elevation of the liquid into other parts of the
plants.</span>
Answer:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
