Answer:
Biocatalyst or enzyme
Explanation:
The Lactose is a disaccharide sugar or carbohydrate found in the milk and the milk products.
The breakdown of the lactase is very difficult but the presence of a protein molecule called lactase-phlorizin hydrolase or lactase makes the breakdown of the lactose int galactose and glucose easy.
Such protein molecules which increase the rate of reaction are called enzymes and since the breakdown of lactose is a biological process, therefore, the enzymes are also known as the enzymes or the biocatalyst they increase the speed of the reaction.
Thus, Biocatalyst or enzyme is the correct answer.
Answer:
Reciprocal cross
Explanation:
a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern. In this type of test cross, male of one genotype and female of different genotype are crossed and the opposite is true as well. ( i.e the female of one genotype and male of different genotype are crossed.)
As we can see in the male Flagus fly with the Barkus phenotype is being crossed with a female with the wild-type phenotype.
In the second test, we can see that the opposite is true of our first statement where the female Flagus fly has the Barkus phenotype and the male has the wild-type phenotype after being crossed again thereby reversing the genotype.
Answer:
2) 25%
Explanation:
Let the traits for the black coat color be = BB
Let the traits for the brown coat color be = bb
Let the traits for heterozygous black coat color be = Bb
Now; the question says what is the probability of producing a rabbit with brown coat color from two rabbits that are both heterozygous for black coat color.
This implies that if two rabbits that are both heterozygous for black coat color cross together;
i.e Bb × Bb ;
The offspring will be (BB, Bb, Bb, bb)
BB (rabbits with black coat color) = 1/4
Bb (rabbits that are heterozygous for black coat color) = 2/4
bb (rabbit with brown coat color) = 1/4
Lets focus on ''bb'' ;
bb = 1/4 × 100%
= 25%
