Which of the following observations would support the claim that a particular mutation is neutral?The frequency of the mutation in a population, once it first appears, tends to increase over time. In a given population, individuals that posses this mutation have a greater rate of reproduction. The mutation is higher in populations of organisms that produce fewer offspring and have shorter life spans. The frequency of the mutation goes up and down with no observable effect on the health of a population.

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol
