The correct answer here is "cell membrane". Generally it makes sure that nothing enters or leaves the cell, except by its highly guarded "gates", such as ion channels, that let some particles through - but they're very picky about whom to let in!
Options have not been provided for the question. They are as follows:
What is the correct order for these genes using a linkage map analysis?
A. Z-X-Y-W
B. X-W-Z-Y
C. W-X-Y-Z
D. Y-W-Z-X
E. Z-X-W-Y
F. Y-X-W-Z
Between which two genes is crossing over most likely to occur?
A. B and D
B.X and Z
C. X and W
D. X and Y
E. W and Z
F. Y and W
G.Y and Z
Answer:
Correct order for these genes using a linkage map analysis: E. Z-X-W-Y
Two genes between which the crossover is most likely to occur: G.Y and Z
Explanation:
According to linkage concept, recombination frequency between two genes = distance between two genes in cM
Here, smallest distance is between X and W ( 7cM ) so they are present next to each other. Distance between X and Y is 17cM and between W and Y is 10cM so W is present between X and Y. Distance between X and Z is 13 cM. Since on one side of X, W and Y are already present Z lies on the other side. So, the final gene order comes out to be, Z-X-W-Y.
According to the gene order, Y and Z genes are farthest from each other. Chances of crossover or recombination increases with increasing distance between genes. So, Y and Z have the highest probability to show crossing over.
Dominant because dominant genotypes overcome recessive genotypes
ATP and NADPH are the carriers of energy
Answer:
by experimental repeatability, which enables to demonstrate the accuracy and reliability of the scientific study.
Explanation:
Scientific ideas and theories are used to explain observations and phenomena from the real world. Scientific validation comes by acceptance of the scientific community, which is generally achieved by scientific publications in well-reputed peer-reviewed journals. In order to be validated, these explanations must be repeatedly tested by using the scientific method, thereby proving the effectiveness of the proposed research method used to obtain information.
