The answer would be A—the molecular formula given is that of a long-chain, saturated fatty acid, which would be insoluble in water (i.e., hydrophobic).
—————————
B describes carbohydrates, which can function as a storage of energy (e.g., starch or glycogen) or structural components (e.g., cellulose). The three examples just given are polymers of glucose, a monosaccharide; monosaccharide generally have the empirical formula CH2O; this is not the empirical formula of the given molecule (and, in any case, there are too few oxygen atoms for the number of carbon atoms), and so B is incorrect.
C describes an amino acid, likely an α-amino acid, which consist of a central, saturated carbon bonded to amino (—NH2) and carboxyl (—C(=O)OH) functional groups and a variable side chain, which determines the amino acid’s properties. Since the formula of an amino acid must contain nitrogen, which the formula given doesn’t have, the molecule couldn’t be an amino acid, and so C is incorrect.
D describes nucleic acids. Examples include DNA and RNA; nucleic acids and the nucleotide monomers that comprise them contain a nitrogenous base and a phosphate group. The given molecule’s formula has neither nitrogen nor phosphorus, and so cannot represent an amino acid, making D incorrect.
Answer: Breaks down, decomposes. Decomposers include bacteria and fungi.
I’m assuming this entire thing is cellular respiration. pathway a most likely represents alcoholic fermentation, B represent lactic acidosis fermentation, C probably represents aerobic cellular respiration. Alcoholic fermentation doesn’t occur in humans, it occurs in micro bacteria and yeast. Lactic acidosis fermentation occurs in humans when there is not oxygen. That’s why you breathe so heavily after sprinting. Cellular respiration just happens naturally. Idk if that’s what the question is asking so feel free to comment and if this helped, brain answer?
Answer:
Explanation:
To fight against new invasion disease . Antigen play a big role
Answer:
The experimental results cannot be reproduced.
Explanation:
The ability to follow a specific set of procedures and achieve the same results is one of the key parts of the scientific method. If the results cannot be replicated, the study is invalid. Unfortunately, results of invalid studies are sometimes announced to the public before replication attempts can be made to invalidate the study. Trying to reverse public belief at that point can be impossible.
