A student is investigating the question “Which increases a person’s breathing rate more after three minutes, lifting five-pound

weights or lifting ten-pound weights?” She designs an experiment to test the question. Which statement most likely describes the dependent variable in her experiment? The breathing rate is the dependent variable because it can be affected by varying weights. She cannot measure the dependent variable until she finishes the experiment. The time of exercising is the dependent variable because it can be measured. The five- and ten-pound weights are the dependent variable because they can affect the breathing rate.

20. calculate the molar enthalpy of vaporization of a substance, given that 0.433 mol of the substance absorbs 36.5 kj of energy
Allisa [31]

The molar enthalpy of vaporization of the substance is 84.3 kj/mol.

<h3>What is molar enthalpy of vaporization?</h3><h3 />

Molar enthalpy of vaporization is the energy required to vaporize one mole of a liquid at its boiling point.

0.433 moles of the substance absorbs 36.5 kj of energy when it is vaporized.

1 mole of the substance will absorb 36.5 kJ × 1 /0.433mol = 84.3 kj/mol

Therefore, the molar enthalpy of vaporization of the substance is 84.3 kj/mol.

antiseptic1488 [7]

Question is incomplete. Complete question has been attached.

Answer:

d. X

Explanation:

According to the given data, Tom is looking for five desirable traits in his hamsters. These traits are dark brown color, white bellies, long fur, black eyes and long tails. He should choose the male which can result in maximum number of the given traits.

We do not have any knowledge about the mode of inheritance of these traits ( dominant, recessive, multiple gene etc. ). So the decision should be eyeballed according to the phenotype present in the male. The male which has maximum number of desirable phenotypes should be mated with the female to increase the chances of bringing the desirable alleles together and thus getting the progeny with the same traits.

Out of the four given options Hamster W, Y and Z have 3 desirable traits whereas Hamster X has four desirable traits ( dark brown fur, white belly, long fur and long tail ). Hence, Tom should buy Hamster X in order to have best chance of breeding baby hamsters with most of the desirable traits.
