The best answer is A. Enzymes work best at a certain temperature, so that if the enzyme is outside it’s ideal temperature, it won’t function normally.
B and C are incorrect because enzymes are made of amino acids, not nucleus acids or simple sugars.
Because the scientists extracted the enzyme from the organism, the amino acid sequence cannot be different between the enzyme and the enzyme in the blood. Thus, D is incorrect.
In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are the amount of water and temperatures. Terrestrial ecosystems rely on the sun's energy to support the growth and metabolism of the organisms. Plants use the sunlight, then they supply the organisms that are higher up the food chain with energy and the structural buildings blocks of life. Water is also essential for the survival of these organisms.
The answer is D. the way organisms grow and develop
Answer: a. Excesses are eliminated from the kidneys.
Explanation:
A fat-soluble vitamin can be dissolved in fats and oils. They are absorbed along with fats in the diet from the intestinal lumen using the same mechanisms used for absorption of lipids. Upon absorption, <u>these vitamins enter the lymph vessels</u> before making they go into the bloodstream. In most cases, fat-soluble vitamins must be coupled with a protein in order to be transported through the organism. <u>This means they are solubilized and transported by carrier proteins </u>to exert their actions.
By last, since fat-soluble vitamins can not be dissolved in water,<u> they are not readily excreted. So they can accumulate in fatty tissues</u> to toxic levels if taken in excess.
