Hormones act on target tissues to regulate the body activities is a <u>true </u>statement.
Explanation:
The main function of the hormones is regulatory in nature and regulates various body activities like the metabolic functions, cellular chemical reactions and transportation of materials.
Each hormone that is secreted from an endocrine gland is specific to a target tissue or an organ as a whole.
A target tissue or organ is the one which is intended to be affected by the hormone action. Receptor sites present in target tissues will act only in response to the specific hormone specified or intended to act upon the target tissue.
The hormonal messages are transferred only to those appropriate receptor sites of the target tissues through chemical bonding and not to other tissues.
For example, the adrenaline gland secretes the hormone adrenaline which acts upon the heart which is its target organ and increases heart rate and helps to prepare the body as a whole for any ‘fight or flight’ situation.
The answer should be:
It would require less force because of the larger distance between the elbow and the location where the force from the biceps acts.<span>It would require less force because the torque for each newton of force from the biceps is greater.</span>
Biceps lever is similar to a door. When you push a door near the handle, it will be much easier than pushing it near the hinge. In this case, the elbow is the hinge and biceps insertion is the push/pull location.
Biceps lever mechanism will be more effective if it muscle insertion became further. The moment arm also increased so the torque is increased too.
The correct answer is:
a. was completed in 2003
It was started in 1990, and run until 2003 (so we know that the first answer is correct and the second isn't). It provided a big amount of important information, but it' didn't allow anyone to alter their appearance, as this is not something that can be achieved via genetics.
The answer to this question would be: <span>B. Receptor site
The receptor site of a neurotransmitter often only receives a specific kind of transmitter. That was because the receptor has a unique 3D structure, so different transmitter wouldn't fit into the receptor. That was similar to lock and key principles.</span>
