If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?
ad-work [718]

Answer;

C. His mother carried at least one allele for that trait

Explanation;

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.

Can enzymes be reused
Masja [62]

If denaturation occurs (extreme temperature change or pH changes), the enzyme will not be reusable! The structure of the enzymes are not changed. As a result of this, enzymes will be used again and again to bind onto another substrate molecule and catalyze the reaction once again.

Which of the above molecules would be least soluble in water?<br><br>(See attached image)​
weqwewe [10]

C

Explanation:

Molecule C would be least soluble in water because it is not a polar compound/molecule. It also lacks any unit that can combine with water to form a good hydrogen bond.

  • The general rule of solubility is that like dissolves likes.
  • Polar molecules will only dissolve in polar solvent.
  • Water is a polar solvent with hydrogen bonds in them.
  • Hydrocarbons typically have weak london dispersion forces between them and they are not polar.
  • Other compounds have functional groups that can form hydrogen bond with water.
