A pure-bred normal tail, dark skin, smooth skin mouse is crossed to a pure-bred mouse that is tail-less, pale skin, and rough skin. What are the gamete genotypes produced by each of these mice?

TTppRR will produce TpR gametes.  ttPPrr  will produce tPr gametes.

Explanation:

Let us assume:

Normal tail : T, Tail less : t, Pale skin : P, Dark skin : p, Smooth skin : R, Rough skin : r

A pure-bred normal tail, dark skin, smooth skin mouse and a pure-bred mouse that is tail-less, pale skin, and rough skin  crossed together then,

TTppRR x ttPPrr

One allele from every gene comes in a gamete thus, TTppRR will produce TpR gametes.  ttPPrr  will produce tPr gametes.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
