Vitamins are organic substances because you get your vitamin D from the sun and the sun is not artificial is it. So that is false
Active Transport<span> is used when substances are to be transported against their concentration gradient ( from low concentration to high concentration ) by utilising energy from ATP.

Carbon is the sixth most abundant element in the planet. Without carbon, life will be non-existent. It provides the framework for all living organisms on Earth. A carbon atom is composed of six protons and six neutrons. Carbon is found in almost everything that surrounds us; they are in fuels, coals, natural gas, even the proteins that make-up hair and meat contain carbon. This is mainly because carbon atoms can bond to other carbon atoms to make a compound. It is naturally found in the environment and its abundance fits its purpose in our existence. <span>A Carbon atoms can bond to other carbon atoms.</span>
Like other herpes viruses varicella is an enveloped DNA virus.
<span>Varicella-zoster virus is a type of herpes virus which infect humans also called chickenpox virus, varicella virus, zoster virus, and human herpesvirus type 3 (HHV-3). Its genome is a linear duplex DNA molecule, it multiplies in the lungs and after the primary infection, it goes dormant into neural cells where it can be reactivated and cause neural diseases.</span>
A windmill’s blades move from the blowing wind. The movement of the blades represents kinetic energy.
The visible light that allows people to see where they are going describes radiant energy.
<u>Explanation:
</u>
An object possesses an energy due to its motion is referred as kinetic energy. Whereas energy due to position of an objects called potential energy.
When the wind blows, its blade catches kinetic energy and rotate to transform into mechanical energy. Hence, the blade's rotation denotes kinetic energy.
Radiant energy is simply energy transmitted by waves or sometimes by particles. It is energy emitted by electromagnetic radiation. It is also a kind of kinetic energy.
Because particles move when they move light, heat and radiation from one source to another. Therefore, Radiant energy denotes when visible light permits people to see where they go.
