Sam’s teacher is trying to model the day/night cycle on Earth. One student holds a large yellow ball to represent the Sun. Anoth
Orlov [11]
Hello!

So, day and night are caused because the earth makes a full rotation on its axis once every 24 hours.

That way, have of Earth is facing the sun (it is morning on that side) and the other half isn't (which is why it is nighttime over there).

For example, if it's nighttime in Canada and America, it's morning in Pakistan and India. This is because Pakistan and India are facing the sun whilst Canada and America are not.

A N S W E R:

The balls should be moved so that half the Earth is facing the sun and the other half is not. This would be 24 hours. As for the sun, it is a gas, not a solid, so it doesn't rotate like one. However, that does not mean that it is not rotating to some extent.

Which statement best describes the age of the seafloor?
Fittoniya [83]
The correct option is B. The newest crust on earth is located at the actual site of the floor spreading and as new crusts are formed they replace it. Thus, the older the crust the farther it is from the mid ocean ridge. 
Sea floor spreading is a geological process in which tectonic plates splits apart from one another. It occurs at divergent plate boundaries.

sammy [17]

The medial pre Frontal Cortex neurons synapting with the intercalated cells of Amygdala contains <u>GABA</u> as the neurotransmitter.

Option a

<u>Explanation:</u>

The Amygdala has two types of nerve cells getting attached with it primarily. They are the fibres from the mPFC or medial pre Frontal Cortex and the vIPAG or ventrolateral periaqueductal grey. These neurons do have different functions on the whole body.

The fibres from the mPFC do have emotional function on the human body whereas the fibres of vIPAG do have an effect on the muscle tone . And it's seen that both the nerve fibres that are getting attached with the intercalated cells of Amygdala do secrete GABA and are inhibitory GAB Anergic in nature.
