An opening in the dermis through which perspiration reaches the surface of the skin is called pores.
<u>Explanation:</u>
Skin is the second largest organ of the human body. The skin in order to regulate the body temperature expels the liquid in the form of sweat. This sweat is normally not pure water. It is a mixture of water with minerals and salts. This process is called as the perspiration. Skin has got sweat glands which is present throughout the body.
This sweat gland through the small holes called pores that expel the sweat. Normally we sweat through arm pits, face, palm of hands and sole of the foot. Women tend to sweat more than men. A normal pure sweat is odorless hence distinctive odor in the sweat can help us identify certain differences the body is undergoing

False , because its backwards
There will be more energy 'locked away' in a massive lorry that is moving at 20 m/s than in a motorbike travelling at the same speed.
Also the faster it goes the more kinetic energy the lorry will have.
A lorry moving at high speed will have much more kinetic energy than a lorry moving at low speed.
Therefore a fast moving car or lorry will cause more damage in an accident than a slow moving one because this kinetic energy has to be turned into other forms including sound, heat and stress on the other vehicles.
The kinetic energy of an object therefore depends on two things:
(a) the mass of the object (m)
(b) its speed (v)
The formula for kinetic energy of an object of mass m travelling at speed v is:
