Digestive juice is the name for all juices secreted by the organs from the digestive system such as salivary glands, stomach, pancreas and liver. All of them contain enzymes that are responsible for food (macromolecule) break down. Digestive juice from the stomach contains enzyme protease (pepsinogen) which breaks down proteins and stomach acids which is involved in chemical breakdown of food materials. So, that is why the wheat grains are broken into tiny particles.
Answer: The correct answer is incomplete dominance.
Answer:
50%
Explanation:
The allele for black fur (B) is dominant to the allele for brown fur (b).
- BB or Bb = black fur
- bb = brown fur
A male homozygous black mouse (BB) is crossed with a female brown mouse (bb). The male parent only produces<em> B</em> gametes and the female parent only produces <em>b</em> gametes. The F1 offspring will be 100% heterozygous Bb.
The F1 individuals will produce <em>B</em> and <em>b</em> gametes. If we cross the F1 individuals to each other (Bb x Bb), we'll get the following F2 offspring:
- 25% BB homozygous dominant
- 50% Bb heterozygous
- 25% bb homozygous recessive
So 50% of the F2 will be homozygous (BB or bb).
