Sex-linked traits punnet squares - please help walk me through it! I’m so confused haha

Explanation:

a) The allele for hemophilia is Xh and that for normal is XH.

Crossing a hemophiliac male, Xh Y, with a normal female XH XH,

XH Xh, normal carrier female
XH Xh, normal carrier female
XH Y, normal male
XH Y, normal male

b) Both parents are normal and children still having hemophilia means that the mother is a carrier.

Let's see how it'll work out if we cross a normal male with a carrier female,

XH Y × XH Xh

XH XH, normal female
XH Xh, carrier female
XH Y, normal male
Xh Y, hemophiliac male

This means that the possibility of a female being normal, a carrier or not, is 100%. The possibility of a male being normal is 50% and the possibility of him being a hemophiliac is also 50%.

Thus it's possible that all 7 sons get hemophilia as each male baby has a 50% chance of having the genotype Xh Y. And it makes sense that all the females are normal. Those females could have the genotypes XH XH, or XH Xh (carriers).

When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on

andreev551 [17]

So, first question:

When we run, we sweat, which means we're getting hotter and hotter and our bodies need to cool down, which they do through transpiration (sweating). If we need to cool down, we need to release the heat that is in our bodies.

To run, we also need to move our muscles, which requires a specific type of energy, called mechanical or kinetic energy, which is the "energy of movement". In our bodies, we don't store that type of energy though, so we have to convert chemical energy to mechanical energy.

Answers: First option and third option.

Second question:

We know that to move we need energy, and that an amazing source of energy is sugar. In this case, the biomolecule mainly used by cells to obtain energy, is glucose, which is a type of sugar.

Answer: B.

Third question:

NAD+ stands for Nicotinamide adenine dinucleotide +, an it has many functions, such as an oxidiser. In this case, in fermentation, it's related to glycolysis.

Glycolysis is a process of energy transformation used by cells, where they convert sugars to biochemical energy. The function of NAD in this case, is "housing" electrons for the process to function normally. Note that during the process, when NAD accepts electrons, it gains 1 proton which converts it to NADH.

Answer: C.
