Answer: A, through extensive testing and the accumulation of several lines of evidence
Explanation:
The waste products of respiration are Co2 and H20.
A dichotomous key helps you identify unknown specimens based on their traits because there are only two options available per trait. Selecting one from the two options (usually contrasting characteristics) from each step leads to smaller and smaller groups until the option is reduced to single and unique trait of an organism.
Considering you need to identify an organism. So, on the top of they key is animal with options: (a) with red blood cells and (b) no red blood cells. The option you will select is no red blood cells and under option b, you’re given two choices again: (a) hard bodies and (b) soft bodies. You’ll select soft bodies, then two options again are given: (a) with shell and (b) without shell. The option you’ll select would be without shell, and so on.
The right answer is "<span>fat soluble are stored in the liver and fatty tissue ...".
Lipids are essentially stored as fatty acids in the cytoplasm of adipocytes. All of these cells form adipose tissue, commonly called "fat".These reserves are much larger in quantity than the reserves in the form of glycogen, in the human body.
"<span>water-soluble vitamins can build to toxic levels ..." is false, hydrosoluble vitamins are rarely toxic, even at high concentrations, and even if they are toxic (which is very rare) is it not due to their circulation in the bloodstream, it is due to their accumulation in cells.</span>
