likoan [24]

Answer:

A to N

Explanation:

Glutamine is an amino acid with a polar, uncharged side chain. The mutation to alanine, an amino acid with a non-polar side chain, completely affects the enzymatic activity. This makes sense considering the difference in the nature of both amino acids.

To restore the wild-type level of activity the alanine would have to mutate to another polar uncharged amino acid. Among the given options, only Asparagine (N) has a similar chemistry to Glutamine.

adell [148]

Answer:

The ball has greater velocity before the collision, so the force affects the ball more than it affects the bat. The ball has less mass, so the equal force on the ball and the bat causes greater acceleration of the ball. The bat exerts more force than the ball because the batter is exerting a force on the bat as it hits the ball
