dimulka [17.4K]

C. mineral

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

What are the base pairs in DNA and RNA?
insens350 [35]
Although very similar, the base pairs in DNA and RNA differ by one nitrogenous base. 

In DNA, the four nitrogenous bases are Adenine, Thymine, Guanine, and Cytosine. Adenine always bonds to thymine (in DNA), they are connected by two Hydrogen bonds. Cytosine and Guanine are always bonded together. They are connected by three Hydrogen bonds. 

However, in RNA, there is no thymine and instead, there is Uracil. That is the only nitrogenous base that is different. Cytosine still bonds to guanine, and adenine bonds to uracil. 

I hope that helps!
