Answer:
6 offsprings with white fur
Explanation:
The gene involved here codes for fur colour in mice where the allele for brown fur (B) is dominant over the allele for white fur (b) i.e. the B allele will mask the expression of b allele in an heterozygous state (Bb).
Since allele B is dominant, in an heterozygous state (Bb), the mice will be brown-furred. Hence in a cross between two Bb parents, a phenotypic ratio of 1:2:1 will be produced where;
1 is BB (homozygous brown fur), 2 is Bb (heterozygotic brown fur) and 1 is bb (homozygous white fur).
Hence, 1/4 × 100= 25% offsprings will be white furred. If 24 mice result, 25/100 × 24 = 6 offsprings will be white.
Although "further disturbances" is pretty vague, both climate change and nonnative species will definitely have a potentially long term impact on an ecosystem
Advantages:
Enhance protein digestion. The addition of a protease to a feed can result in improved amino acid digestibility across various protein sources. Minimize the impact of anti-nutritional factors.
Disadvantages:
Enzymes can be denatured by even a small increase in temperature. They are also susceptible to poisons and changes in pH. This means the conditions they work in must be tightly controlled
Enzymes can be expensive to produce
Contamination of the enzyme with other substances can affect the reaction.
Hope it helps!
The answer will obviously be letter A
