Answer:

Metaphase.

Explanation:

Metaphase may be defined as the stage of the cell cycle followed after the prophase and before the anaphase. The chromosomes are joined together with the centromere.

This stage can easily be identified in the microscope. The chromosomes are aligned themselves at metaphasal plate in the center of the cell.

Thus, the answer is metaphase.

Answer:

UCS: sticks part of the toy into the electrical outlet

UCR: frightened and crying

CS: toy

CR: frightened to toy

Explanation:

Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.

<u>Unconditioned stimulus</u> (UCS) is an agent that leads to a response without training. In this example, the child won't know that he can have electrical shock playing with toys.

<u>Unconditioned response</u> (UCR) is an automatic response to a UCS that's why the child starts crying and frightened.

<u>Conditioned stimulus</u> (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.

<u>Conditioned response</u> (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.
