It is the decreasing effectiveness of antibiotics. The reason for this could possibly be because the bacteria has had a mutation so the antibiotic won’t affect them.

This is the role of a species in an ecosystem, consisting of such things as what it eats, when it eats, and where it lives.
dybincka [34]
The answer that would best complete the given statement above is the term NICHE. Each specie has a role in an ecosystem to make it balanced. And an example of this is when s<span>mall monkeys and squirrels both eat nuts and live in tree tops. Hope this answers your question.</span>

A molecule with the formula C18H36O2, would probably exhibit which of the following characteristics?
Mashcka [7]
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.

<span>Answer: A) Dark moths had a survival disadvantage in industrial Dorset.

-----

This question can be solely answered using the data you're given! The graph is broken down by place, and then moth type.

In forested Birmingham, the green bar for the light moth is much higher than the orange one for the dark moth. That means the light moth had a survival advantage (eliminating option D) and the dark moths had a survival disadvantage (eliminating option C).

In industrialized Dorset, the green bar for the light moth is much lower than the orange one for the dark moth. That means the light moths were at a survival disadvantage (eliminating option B). The dark moths were are a survival advantage, but option A says "disadvantage," which is clearly wrong! That makes A your answer.
