For any terrestrial planet in the solar system, the core would be the densest layer, and the crust would be the least dense layer.
<h3>Answer & Explanation .:</h3>
---------------------------------
The woman inhales oxygen produced by the plant in the process of PHOTOSYNTHESIS,
and she use it inside her body to release energy from the food molecules by the process of RESPIRATION also as a result of respiration Carbon dioxide gas is produced, which she exhales.
That carbon dioxide is absorbed from air by the plant and use it to prepare food from it in the presence of sunlight by the process of PHOTOSYNTHESIS in which oxygen is also produced as byproduct which is then released to air and is then inhaled by the woman again to repeat the cycle.

Take for example - you touching something sharp and instantly moving your hand away.
Sensory neurons in your fingers detect the external stimuli of the sharp object and send a nerve impulse to the spinal cord (does not reach brain) and is sent back to a motor neurone - attached to an effector that moves the muscle and moves the hand away. This is a rapid reflex action and involuntary.
Answer: Inorganic compounds <em>are </em>made of elements.
Explanation: Everything in the universe, whether living (organic) or not (inorganic), is made of elements.
weight=mass*gravitational accelaration
we know the weight and the gravitational acceleration
400N=m*10m/s^2
m=400N/10m/2^2
m=40kg
