White wool (W) is dominant over black wool (w).

Brown eyes (B) is dominant over blue eyes (b).

A sheep with black wool (ww) and brown eyes (Bb) is crossed with a sheep with white wool (WW) and blue eyes (bb).

<h3>wwBb x WWbb</h3>

If there is independent assortment between genes, the genotypes of the first parent's gametes will be wB and wb. The gametes of the second parent can only be Wb.

<u>The resulting offspring will be:</u>

  • 1/2 wWBb , White wool and brown eyes.
  • 1/2 wWbb , White wool and blue eyes.

How enzymes inhibitions studies in the formulation and development of drugs​
lesya [120]

Answer:

Enzyme inhibitors may alter the elimination rate of a particular drug or inhibit detoxication pathways

Explanation:

An enzyme inhibitor is a chemical compound capable of binding to an enzyme in order to reduce its activity. An enzyme inhibitor may bind to an active site and thus decreases the rate of reaction (direct inhibition). Enzyme inhibitors may act 1-to Inhibit detoxification enzymes and 2-reduce the elimination rate of enzyme drugs, thereby having dose-dependent toxicity effects. For example, many medicines are based on the inhibition of Cytochromes P450 (CYPs) proteins, which are a superfamily of enzymes required for drug metabolism.
