A molecule with the formula C18H36O2, would probably exhibit which of the following characteristics?

Biology
1 answer:
Mashcka [7]3 years ago

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.

What are some steps that scientists can take in designing an experiment to avoid false negatives?
Alchen [17]
False negative is a condition when you got a negative result for a specimen which was positive. To prevent false negative occur, first you need to use golden standard test or a test with high specificity. You can do multiple tests to ensure the specimen is negative and using a positive control to make sure the reagent is still working fine.

Imagine that a rancher has a herd of cattle with brown hides and short horns. All of his cattle are also relatively short in sta
dmitriy555 [2]

Answer:

The correct answer would be option D.

Explanation:

True breeding is a breeding procedure in which the parents would always produce their progeny with the same phenotype characters as the parents carry. This means for every trait these parents are homozygous so their offspring must show a similar phenotype.

In this case, all cattle are true-breeding which means they homozygous alleles show the progeny will also show similar traits which are short stature with brown hides and short horns.

Thus, the correct answer is option D.

List the four types of stem cells, give an
Flauer [41]

Answer:

Totipotent Stem Cells - They can differentiate into any type of human body cell or the placenta.

Example: Fertilized egg cells.

Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.

Example: Blastocyst cells.

Multipotent Stem Cells - They can only differentiate into closely related cells.

Example: Blood stem cell

Unipotent Stem Cells - They can only produce their type of cell.

Example: Skin stem cells (which can only become a new skin stem cell).
