The correct answer is 2. By a feedback loop.
Hormone levels in the body is regulated by negative feedback mechanism. In this mechanism, a stimulus stimulates the release of a substances. After the effect of that substance its further release is inhibited. This can be understood by an example, the anterior pituitary gland stimulate the thyroid gland to release thyroxin and on increasing the thyroxin in the blood, feedback the hypothalamus and anterior pituitary to inhibit further release of thyroxin from thyroid gland.
Answer:
b) Tendon
Explanation:
Tendons are fibrous, thick, stiff and flexible structures, with a whitish color, present in different parts of the human body.
They are part of the striated muscle being made up of connective tissue (composed of collagen).
The main function of the tendons is to connect the muscles to the bones. In this way, it helps in the balance of the body and in the development of movements, distributing the forces in the muscles.
As it pulls the connecting bone with the muscle, the tendon creates the movement in order to transmit the force of the contraction to the bone.
In addition, the tendon provides stability to the joints (meeting point between two bones) of the body's joints.
The answer is A

Answer:
The correct answer is <em>They move through an electron transport chain to Photosystem I.</em>
Explanation:
Luminous energy is trapped by a chlorophyll molecule in the <u>Photosystem II</u>. When the pigment molecules absorb light, electrons get in a higher energy level. These excited electrons go through the electron transport chain to an inferior energy level in the <u>photosystem I</u>. When the excited electrons leave photosystem II, they are replaced by new electrons that are extracted from the water molecules. As electrons go through the transport chain, their released energy is used to <u>produce ATP molecules</u>. Luminous energy absorbed in the photosystem I move the electrons to another electron acceptor from where they are transported again and used to produce NADPH molecules. When electrons are eliminated from Photosystem I, they are replaced by new electrons that are coming from the photosystem II through the transport chain.
