 Last Quarter (half visible) 

Explanation

It moving from new moon towards full moon.

Explanation

Energy is measured in units of kilocalories

One kilocalorie  is equal to 4.18 kilojoules.

The amount of energy a food contains per gram is known as its energy density,

So we can describe fat as more energy-dense than protein or carbohydrate.
