If your pores appear larger, it may be because of: acne. increased sebum production, which causes oily skin. These tiny holes are everywhere, covering the skin of your face, arms, legs, and everywhere else on your body. Pores serve an important function. They allow sweat and oil to escape through your skin, cooling you off and keeping your skin healthy while getting rid of toxins.

Sodium reacts violently with cold water to form sodium hydroxide solution along with the evolution of hydrogen gas.

2Na     + 2H2O  →  2NaOH + H2

Since, sodium reacts vigorously with the oxygen and water producing a lot of heat, it is stored in kerosene.

  • If net addition of all the forces is not zero then the forces are termed as unbalanced forces.
  • If an unbalanced force is applied on object it will have acceleration. And the acceleration will be there as long as the force is there.
  • After the force is removed it will continue to move with the velocity it has gained till then.

Fertilization is the first step in sexual reproduction. When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus which results in the formation of a fertilized egg or zygote. It is due to fertilization that the new individual inherits some characteristics from the mother and some from the father.
