Answer:
When we stand on the floor, we apply a force on the floor surface in the downward direction and in return the floor also exerts an upward and equal force on us.
Explanation:
Newton' third law is vey famous and it states that for each and every action, there applies an equal but opposite reaction. Thus the action force and the reaction force always acts on pairs. But they does not contribute to the motion of the object.
One such example that illustrates the action and reaction force from Newton's law is when we stand on the floor we exert a force on the floor surface in downward direction. The floor surface also exerts an opposite and equal force on us in the upward direction.
Almost all plants and animals go through either photosynthesis or respiration!

Answer: Option (d) is the correct answer.
Explanation:
A covalent bond is defined as the bond formed by sharing of electrons between the two chemically combining atoms.
For example, atomic number of chlorine is 17 and it has 7 valence electrons.
To attain stability it need to gain one more electron.
So, when one chlorine atom chemically combines with another chlorine atom then there occurs sharing of electrons between the two. As a result, there will be sharing of electrons.
A molecule is defined as the specie that contains same type of atoms which are chemically combined together in a fixed ratio by mass.
