Answer: 2
Explanation:- Mechanical advantage is the ratio of the output force to the input force.
Mechanical advantage=
Given:
Input force = 320 N
output force= 640 N
The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.
The body system that would be directly affedted is the immune system
This is an example of a symbiotic relationship, where both species or organisms benefit from the interaction between each-other.

Answer:
1. Passive transport across a cell membrane requires no energy. It will happen even if the cell is dead.
2. Active transport across a cell membrane requires energy. It will not happen if the cell is dead.
