Mantle convection describes the movement of the mantle as it transfers heat from the white-hot core to the brittle lithosphere. ... Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.Aug 11, 2015
The answer is the outer core.
The outer core of the Earth is made up of liquid metal. The liquid in the outer core pass through the magnetic field and this causes the flow of electric current with in it. The magnetic field gets stronger as the liquid metal passes through it. What makes the liquid metal move is the inner core. It heats up the outer core which triggers convection.
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:
W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
Hope this answers the question.
