My guess is that fat-soluble toxins that may occur in freshwater ecosystems would most affect apex species in these ecosystems. This is because fat-soluble toxins are stored in the fat reserves of animals, and then bioaccumulate up the food chain. So in this case, most of the toxin is not secreted, but stored within the food chain, and bioaccumulates, with the concentration becoming higher the further up the food chain.

Answer:

When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.

Explanation:

If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.

The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.

Answer: Adrenaline, also known as epinephrine, is a hormone and medication. Adrenaline is normally produced by both the adrenal glands and a small number of neurons in the medulla oblongata, where it acts as a neurotransmitter involved in regulating visceral functions (e.g., respiration).It plays an important role in the fight-or-flight response by increasing blood flow to muscles, output of the heart, pupil dilation response and blood sugar level. It does this by binding to alpha and beta receptors.[

Asbestos breaks down into small fibers. What may result if these fibers are inhaled?
jeka57 [31]
When they are breathed in, they can become trapped in the lungs and stay there for many years. Many problems might result in accumulation of such. One would be asbestosis, an inflammatory condition of lungs that can cause shortness of breath. Another would be mesothelioma, a rare cancer that affects the lining of the lungs, chest cavity, or abdomen.
