I say C. <span>it lowers the activation energy of a reaction in affects only very specific reactions. Correct me if I'm wrong tho...thank you ;)</span>
The right answer is <span>A) semi-permeable membrane
<span>A semi-permeable membrane is a membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute).
</span>The tubule of a kidney consists of a semi-permeable membrane and has also specific transporters which allow absorption and reabsorption. These "tools" allows some substances like ions to be absorbed/reabsorbed (by the transporters), without any changes in the concentration of the other substances (because both the membrane and the transporters stopped them).</span>
The antidiuretic hormone, otherwise called vasopressin is made in the region of the brain called hypothalamus. The cells of the hypothalamus excrete this hormone through the connection they have with the pituitary gland. From this gland, the hormone is released into the bloodstream and eventually comes down to kidneys, affecting the kidney tubules, making them conserve water by transporting them back to the bloodstream.
Answer:
Enzymes are proteins that allow certain chemical reactions to take place much quicker than the reactions would occur on their own.
Explanation:
Enzymes function as catalysts, which means that they speed up the rate at which metabolic processes and reactions occur in living organisms.
Answer:
I think this is the list right? - Felis catus Sylvilagus audubonii Parus inornatus Euarctos americanus
Explanation:
When two members of the same species (male and female) mate, they produce fertile offspring.
The conclusion that can be drawn from this is that due to the fact that from looking at the scientific names of the animals, there are different genus and species names, there would be no interbreeding between them as they do not belong to the same species.
And if peradventure there is crossbreeding, the union would be unable to produce fertile offspring.
