Explanation:
Hormones are the chemicals which are secreted by the glands and tissues of the body. These hormones are transferred into the circulatory system of the body where they are targeted to the tissues for regulating their actions.

This cascading effect can be seen at the enzymatic level the activation of one enzyme causes the activation of other enzymes regulated by the hormonal control.

Answer: C. i. potential, ii. kinetic, iii. potential and kinetic
Explanation: Potential energy is the energy that is possessed or exhibited by an object or a body that is static or stable. THE FORMULA FOR POTENTIAL ENERGY IS P.E = MASS OF AN OBJECT* HEIGHT * FORCE OF GRAVITY
Kinetic energy is the energy of an object or a body that is in motion or it is moving from one point to another.
THE FORMULAR FOR KINETIC ENERGY IS 1/2*MASS OF AN OBJECT *VELOCITY OF THE OBJECT SQUARE.
Answer:
B
Explanation:
Ferns are in the group pteridophytes. These plants have a vascular system – which also means they have true roots, stem, and leaves-, however, they produce through spores (not seeds like higher plants-gymnosperms and angiosperms). Other than ferns, other plants in the group are horsetails and club-mosses. Unlike in higher plants, where the gametophyte is the dominant phase of the life cycle, the sporophyte is the dominant phase in pteridophytes and other lower plants.
