5. Why do males always exhibit recessive traits car-
ried on the X chromosome that they inherit from
their mothers?

males are more likely than females to an inherent a trait on the x chromosome

Explanation:

this is because males have XY chromosomes and females have XX. so if the trait is recessive, females may have it on one x but not the other. so the other x that doesn't have it is dominant and basically covers up for the trait and blocks it from being expressed. but in males, their chromosomes are XY, so they don't have an extra X to block the trait from being expressed. if they get the trait, they have it no doubt

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
