Answer:
The diagram is showing structure of muscle.
Muscles are responsible for contraction and expansion during the body movement. Each muscle is consist of several other fibers such as fasicle, muscle fiber, myofilament and microfibril.
As shown in the diagram, muscles carry fasicles, which are which is type of connective tissues. Fasicles then comprise of bundle of muscle fibers. Muscle fibers carry proteins called myofilamentand myyofilament carry microfibrils.
Democracy, Africa ruled by Africans, end of segregation and racism, improving the economy and using the resources instead of being used by others etc.
Explanation:
Nelson Mandela is a famous historic figure from South Africa. He is best known for leading a movement for ending the apartheid in South Africa and promoting rights for the black people of this country. Also, Mandela was elected as the first black president of South Africa.
The ideals and beliefs of Nelson Mandela were that there should be no segregation and racism in South Africa. Everyone should have the same opportunities in life. Africans need to rule the African countries, not the white people. There should be democracy established. The resources with which South Africa is rich should be used by South Africa only, not to be exploited by other countries.
While all of these ideas seem to be good in general, in practice it didn't really had any particular positive effect. South Africa has been ruled by Africans for around three decades now. The conditions in the country have not improved. There's no real democracy. The racism is widespread, just that now the cards have reversed and it is the black population that terrorized the white population. The economy is similar situation and is everything but prosperous and powerful one.
Answer:
Variable Ratio Schedule
Explanation:
First, there are two different types of reinforcement:
The positive reinforcement applies a stimulus to increase the frequency of the desirable variable.
The negative reinforcement removes a stimulus to increase the frequency of the desirable variable.
However, the positive reinforcement divides itself in different types:
A continuous reinforcement schedule gives us a reinforcement every time we engaged in the desired conduct.
On the other side, the partial reinforcement schedule also divides itself in
And these divide themselves in fixed or variable.
- The fixed ratio schedule gives a reinforcement after a <u>fixed number</u> of desired responses.
- The variable ratio schedule gives a reinforcement after a <u>changing</u> <u>number</u> of desired responses.
- The fixed interval schedule gives a reinforcement after a <u>constant amount of time.</u>
- The variable interval schedule gives a reinforcement after a <u>variable amount of time.</u>
In the example, the rats get a pellet of food, so we're talking about a reinforcement. They <u>don't get a reward EVERY TIME</u> they press the bar so we are not talking about a continuous reinforcement but a partial reinforcement. Since the rats press the bar and get a reward after certain <u>NUMBER</u> of times, we're talking about a ratio schedule. Finally, the number of times they need to press the bar to get a reward <u>VARIES</u> from trial to trial so this is a Variable Ratio Schedule.
