Increase in bone density. Bone hypertrophy occurs in response to physical activity.
Answer: TRUE
Explanation: Myelin is a thick layer of lipoproteins that "wraps" the axons of some nervous cells in a discontinuous form. In electric terms, MYELIN, reduces the membrane capacitance because this layer is to thick to allow the action potential of the entire axon, to depolarize a complete nervous cell.
That is why there are some structures called <em>Ranvier Nodes, </em>those are spaces between every "wrap" of mielina, that have voltage sensitive sodium channels. This space between myelin sheaths, allows a "saltatory nerve conduction", that transmit the electrical impulse from one <em>Ranvier Node </em>to another, becoming the transmition in one of the fastest in the body. If this system would not exist, then the nervous transmision would be very slow.
Answer:
D. obsessive-compulsive disorder
Explanation:
Obsessive-compulsive disorder (OCD) is an anxiety disorder characterized by recurrent and disturbing thoughts (called obsessions) and/or repetitive, ritualized behaviors that the person feels driven to perform (called compulsions). Obsessions can also take the form of intrusive images or unwanted impulses.
In behavioural terms, drugs like aspirin are considered negative reinforcers because they stop a person from feeling pain.
Negative reinforcement is a method that can be used to help teach specific behaviours. With negative reinforcement, something uncomfortable or otherwise unpleasant is taken away in response to a stimulus. Over time, the target behaviour should increase with the expectation that the unpleasant thing will be taken away.
For negative reinforcement to work, whatever is taken away must be taken away immediately after the behaviour in question. The end result is to get whatever behaviour is happening to continue and even increase.
Example :
A person hears a loud alarm. They push the STOP button on the alarm to make the noise stop. Now whenever the alarm goes off, they push the STOP button as quickly as they can.
- Before behaviour: Loud alarm
- Behaviour: Person turns alarm off
- After behaviour: No more annoying sound
- Future behaviour: Person pushes STOP every morning to quiet alarm
