<span>All are mutagenic because they cause base substitutions, deaminating agents oxidatively deaminate bases so cytosine converted to uracil and adenine converted to hypoxanthine, uracil pairs with adenine and hypoxanthine pairs with cytosine, alkylating agents donate alkyl group to amino or keto groups altering base pair affinities</span>
Answer:
The correct answers are:
1 a. X^RX^r - red eye color female
b. X^RX^R - red eye color female
c. X^RY - red eye color male
d. X^rY - white eye color male
e. X^rX^r - white eye color female
(2nd part can also be answered by above)
Explanation:
It is given that the eye color is a sex-linked character where Red eye color is dominant over white eye color in fruit flies. Sex-linked characters are the character that is a similar inheritance pattern except in the case of the male as there is a Y chromosome that does not carry the gene for the eye color trait so the trait will depend on the allele present on a single X chromosome in males.
On the basis of this, the sex and color of eyes will be:
a. X^RX^r - red eye color female - Dominant character will mask the recessive white color and two copies of X which means female.
b. X^RX^R - red eye color female - both copies are dominant so red-eye color will be expressed and two copies of the X chromosome that means female
c. X^RY - red eye color male - One X and one Y chromosome that means male and only dominant allele present so red eye color.
d. X^rY - white eye color male - Only allele that is present is recessive with one Y chromosome that means male with white eye color.
e. X^rX^r - white eye color female - two X chromosomes with recessive allele which means white eye color female.
Answer:
Diffusion
Explanation:
Diffusion is the process through which molecules in the cell are kept in balance with those outside the cell.
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.
Through the above mechanism, molecules having higher concentration in the cell move out of the cell and vice versa thereby maintaining the balance of molecules in and outside the cell.
Answer: A Test for Antimicrobial Activity.
Explanation: A Zone of Inhibition test, also called a Kirby-Bauer Test, is a qualitative method used clinically to measure antibiotic resistance and industrially to test the ability of solids and textiles to inhibit microbial growth.
Answer:
The color comes from one of the parents having the Cr (creme) gene thus creating the palomino color.
