Answer:
The correct answer will be- Elevation
Explanation:
The movement of the muscles attached to the skeleton system allows the movement of the body parts.
The motion of the body parts like joints, limbs, organs are represented by the specific terminologies in which the movement of the scapula towards the head is known as the "Elevation". The elevation represents the superior movement of the body parts.
Thus, Elevation is the correct answer.
a. hybridization
b. incomplete dominance
c. true-breeding
d. the law of segregation
e. polygenetics
Answer:
c. true-breeding
Explanation:
True-breeding is a type of breeding which involves a cross between two parents that are homozygous for a trait leading to the production of offspring from generation to generation that have genotypes that express the same phenotypic traits. The parent plants with purple flowers in the question, are both homozygous for flower color.
Answer:
I would say everything's correct except the second one, I believe that one is false :) I hope you do well and sorry if i'm wrong!
Explanation:
Biotechnology is changing an organism’s genes to make new molecules, B.
Answer:
a). At least one intron must be present in gene X.
b). At least two intron must be present in gene Y
c). It is impossible to determine whether there are any introns in gene Z.
Explanation:
Introns may be defined as the segments in the RNA molecule or the DNA molecule that does not code for proteins and they interrupts the sequences of each of the molecules.
In the context, we get :
a). In the gene X, at least one of the intron is present. Sometimes more than one introns may also be present. Due to slicing, we get one band less in the cDNA which is made from the mRNA.
b). In dene Y, at least one intron is present. Sometimes more than one introns are present inside the gene Y. In this case we get two bands less in the gene due to slicing.
c). In gene Z, it is not possible to determine the number of introns present in them. In genes X and Y, the Haelll enzyme is present in the intron. Therefore we get less of band after splicing the mRNA to cDNA.
