1.Gravity caused the disk-shaped nebula to shrink.
<span> A cloud of gas and dust started to shrink or more corectly started condensate, due to the force of its own gravity. This process started slow, but increased in velocity as more material were moving toward the center.</span>

2.<span>Rotational motion caused the nebula to flatten out in its disk-like shape.</span> The nebula spined counterclockwise to conserve the angular momentum of the material of the material that were going to the center. This rotation, made the materials that were not in the center flatten out, that's why it looks like a disk.

Which situations would be most likely to engage the anterior cingulate cortex?
maria [59]

Answer:

Which of the following situations would be most likely to engage the anterior cingulate cortex?

A waiter walks over to your table at a restaurant and holds an open menu in front of you.

You walk into the elevator of your apartment building and press the button for your floor.

You enter your classroom and find someone sitting in your usual seat.

A good friend asks you to remind him of your telephone number.

Explanation:

In order to meet the demand of the surrounding environment   by adjusting  the  motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.

Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.

Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and  possessing  of memory and learning.

it is also a major  parts of  of pain networks for pain modulation and perception.

Therefore whenever there is  change in the environment  from the prestored condition in the brain,(e.g the usual seat  in the class room  occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case  leads to the reclaiming of the seat or any other necessary proactive action.

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.
