Answer: Option B - There are more than four genes that determine this trait.
Explanation:
The tobacco plant species have its leaf colour with characteristics that changes gradually over a range of values, which refers to continuous variation.
Note that continuous variation keep expressing gene variants in successive generations of the tobacco plants, that differs from the parents. So, there are MORE THAN four genes controling the expression of varying phenotypes in the leaves
Answer:
Glycogen phosphorylase catalyzes the conversion of glycogen to glucose-1-phosphate.
Explanation:
Glycogen phosphorylase catalyzes glucose-1-phosphate release by phosphorolysis from the terminal residue of a non-reducing end of a glycogen branch. A molecule of inorganic phosphate attacks the C1 side of a α(14) glycosidic bond, leaving in the glycogen polymer a hydroxyl group on C4.
