In the initial period of learning, ________ describes when an organism learns to connect a neutral stimulus and an unconditioned
Kipish [7]

Answer:

Option A, Acquisition

Explanation:

The first stage of learning is known as acquisition. It causes establishment of responses by pairing of Neutral stimulus, conditioning and un-conditioning stimulus. Once the association between a neutral stimulus and conditioned stimulus is established, the responses are acquired.  

For example – If a bird is trained to pick a key whenever there is a  sound of a bell, then after certain period of time an association will be established between the “ringing of bell” and “picking up of key” activity. Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.

Thus, option A is correct.

What causes the doldrums to be calm winds?
arlik [135]

Earth revolves around the sun, keeping doldrums stationary causes the doldrums to be calm winds. Thus, the correct option is C.

<h3>Why are the doldrums so calm?</h3>

The Intertropical Convergence Zone, also known as the doldrums or calms by sailors due to its constant lack of wind, is the area where the northeast and southeast trade winds meet. It encircles the Earth near the thermal equator, however its exact location changes with the seasons.

The sunlight beams down directly on the area around the equator, the Doldrums are caused by solar radiation from the sun. Instead of blowing horizontally, this heating causes the air to warm and climb straight up. As a result, there is little or no wind for weeks at a time.
