Answer:
<u>Origin:</u> In biology, origin can be described as the location where the muscle joins a stationary bone and as a result, no movement occurs.
<u>Insertion: </u>In anatomy, insertion can be described as the point of attachment which allows movement of a bone to occur. It moves when the muscles contract.
<u>Tendon:</u> In biology, the tendon can be described as a type of connective tissue which attaches a bone to a muscle.
The correct terms to fill in the blanks are lateral ventricles and venous sinus blood. Cerebrospinal fluid (CSF) is formed by lateral ventricles and reabsorbed through arachnoid granulations into the venous sinus blood. The CSF is a fluid that is clear and colorless found in the spinal cord and in the brain, generally the central nervous system. The CSF functions as a buffer or a shock absorber for the brain. It provides basic mechanical protection for the brain. Also, it helps in the circulation of nutrients and the chemicals that are filtered and aids in the elimination of waste products.

Explanation:
Atoms sharing valance electrons

This is a positive feed back mechanism. This mechanism enhance or amplify changes. This tends to alter the balance away from equilibrium because one hormone will increase the release of the other hormone. An example of this is the child birth. During labor, oxytocin is released to increase the uterine contraction the release of oxytoocin will be induced by the contractions of uterus. This will go on until the child was born. Just remember positive feedback enhance the original stimulus.
