Answer:
Option A
True
Explanation:
Adenosine triphosphate (ATP) is the molecule in the cells that carry energy. They help to trap the energy that is obtained during respiration and the breaking down of food, in order to release it to the cells of the living organisms when the need arises.
Once the ATP levels deplete in the body, cellular fatigue begins to occur, as the cells do not have the required energy to perform their necessary functions.
This makes the correct option to be A: True. The depletion of the ATP levels in the body causes fatigue
Answer is C - crust, mantle, outer core, inner core.
Crust -
Crust is the <em>outermost layer</em>. The thickness of the crust is about<em> 5 - 70 km.</em>
Mantle -
Mantle is the<em> second layer</em> from the Earth's surface. Thickness is about <em>2890 km.</em>
Mantle can be divided into two parts as <em>upper mantle and lower mantle.</em>
Outer core -
The thickness is about <em>2400 km</em>. It is made from mostly <em>iron and nickel.</em>
Inner core -
The <em>innermost part</em> of the Earth is inner core. Mainly made from <em>iron-nickel alloy</em>. It is solid sphere which has a radius <em>about 1220 km</em>.
