Vascular plants is the phloem, (vessal) that transports food and the xylem transports water. Nomvascular plants are small with no vascular system. Which means non vascular plants do not have a phloem or a xylem.
For the first question, the age of each strip of rock is needed to determine the rate of seafloor spreading. The answer is B.
For the second question, the answer is A.
Answer:
(a) When the enzyme phosphorylase is allowed to treat with the ATP and phosphorylase kinase, this helps in the activation of the more active form of the phosphorylase. This increase the process of the glycogen breakdown in the cell.
(b) PP1 ( protein phosphatase 1) removes the phosphate group from the substrate that results in the activation of the less active form of the enzyme. The process of glycogen breakdown in the cell will decrease.
(c) The hormone epinephrine causes the release of cAMP that increases the kinase activity. The active form of the enzyme predominates and increases the glycogen breakdown in the body.
