Well there are many factors that go into the categorization of different life singers in each aquatic system, from the ph levels in the water, the temperature, the depth, the presence of lights, as well as foreign factors s as well such as natural disasters, human/unnatural predatory fishing (invasive), and not to mention pollution, all of which can change the balance of an aquatic system to a minimal degree to turning it into an ecological “dead zone”

Answer:
hi, this is the answer of your question
the cells that line your stomach can renew as fast as every two days, because they in contact with digestive acid.
Correct option is A)
There are electrical and concentration gradients in neurons that induce the sodium ions to enter the cell. The resting potential is maintained because the channels for sodium ions are closed. The membrane remains impermeable to sodium ions in the rest state. The membrane is more permeable to potassium passage. The potassium ions leak through the membrane at a greater rate than sodium enters. There is loss of positively charged ions from the inner part of the cell membrane. The inner part of the membrane carries a relatively more negative charge than the outer part of the cell membrane.
Thus, the correct answer is option A.
Answer:
El flujo de la energía es unidireccional.
