The particles that make up matter are the atoms.

Atoms do not change during a chemical change. They do not either during a physical change.

During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.

For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.

The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.

What is the correct order of genetic material from smallest to largest?
Ede4ka [16]

Answer: allele, gene, DNA, chromosome, nucleus

Explanation: An allele is a variant of a gene or a different form of a gene. A gene is a segment of a DNA that codes for an RNA or a protein. A DNA is a genetic material that contains all the genetic information of an organism. A DNA is packaged and condensed into a threadlike material known as chromosome and chromosomes are found in the nucleus of a cell.

Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA,
Colt1911 [192]

Answer:

G=21 %

T= 29 %

A= 29 %

Explanation:

Since C only binds to G, you have the same amount of C and G, so G is 21 %.

100 % minus 42 % ( 21 % C plus 21 % G=) equals 58 %.

So the other 58 % is made of T and A. Since T only binds to A , the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A

Cell wall - Adds structural support to the cell. Holds the cells together
Cell membrane - Serves as a barrier to the cell and allows more nutrient and molecules to move in and out of the cell without letting things that can harm the cell in. 
Outer membrane - Serves the same basic functions a the cell membrane. (Depending on how complicated the class your in is, I would visit this website for more information... https://en.wikipedia.org/wiki/Bacterial_outer_membrane )
Pili - Help the cell move and attach the bacteria to surfaces are other cells. 
DNA - Contains the genetic instructions on what the cell can physically do, operate, and reproduce. 
Flagellum - Helps the cell move. It kind of acts like a propeller for the cell so that it can move around.
