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:
What is the mechanical advantage of a lever that has an input arm of 3 meters and an output arm of 2 meters? 3. A lever with an input arm of 2 meters has a mechanical advantage of 4.
Explanation:
key.
Answer:
2 : 1
Explanation:
- The surface area of the cube;
Area of one (1) side * 6 sides = 3 *3 * 6 = 54 cm²
Length * Width * Height = 3 * 3 * 3 = 27 cm³
- Surface area – to – volume ratio;
54 : 27 = 2 : 1
The answer is; in the stroma. The chloroplast is the organelle inside the plant cell that performs the process of photosynthesis. Photosynthesis contains two kinds of reactions, the first is the light reactions which happen in the grana as it contains chlorophyll which absorbs light energy. The products of the light reactions are used to fix carbon dioxide in the second reactions which are the dark reactions. The dark reactions happen in the stroma outside the grana. Therefore, the stroma contains more carbon.
