Answer:
Sodium acetate is a type of salt. When water is added to sodium acetate, the chemical bonds break down, causing it to separate into sodium ions and acetate ions. Then acetate ions in the water then combine with hydrogen atoms to create an acid called acetic acid.
Explanation:
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.
The Brain Stem connects the spinal cord to the brain.
Probably 3 %. a mother could give birth to a child with Trisomy 21 at any age because Trisomy 21 is a mutation and mutations happen all the time. Not all mutations are as Down Syndrome. A child born to two homozygous brown eyed parents could be born with blue eyes even if no one in the family had blue eyes. The child would develop blue eyes due to mutation.

Answer:
only appear in veg plants
Explanation:
Unlike other forms of asexual reproduction in plants such as vegetative plant propagation via cuttings, apomixis is asexual reproduction via seeds. In the case of most dandelions (i.e., Taraxacum officinale), the embryo in the seed forms without meiosis, thus the offsping are genetically identical to the parent.
