I'm not sure if this what your looking for but, electrons, neutrons, and protons are the three components that make up an atom.
Electrons are negative
Protons are positive
Neutrons are neutral (or in other words have no charge)
Answer: Blood contains numerous biconcave cells called erythrocyte , contained in a featureless matrix called plasma
Explanation:
Blood is a liquid contain in the body of man and animals that transport the necessary nutrients and oxygen to the cell and then takes away metabolic waste from the cell. There are numerous cells in the body which are the Red blood cells and also the red blood cell.
This red blood cell is also called erythrocyte which is the numerous biconcave cells. This white blood cells and erythrocytes are all in the blood plasma. Both the erythrocytes (i.e red blood cell) and the white blood cell are all contained in a featureless matrix called the plasma.
This plasma is made up of blood, water, carbon dioxide, dissolved proteins, and hormones.
<u>Brief description about how the SHAPE of DNA:</u>
DNA is a double helical structure. The structure of DNA was described by Watson and Creek. They were scientists who got the structure of the DNA by Xray crystallography. They said that the DNA is a double helical structure that is composed of two sugar phosphate backbones that are having one nitrogen base on each sugar molecule.
Each sugar phosphate backbone is at an angle of 36° with the preceding or the succeeding one. They are placed at 20A apart. Each nitrogen base is either Adenine, thymine, guanine or cytosine. Adenine is complementary to thymine and guanine to cytosine. They are complementarily present on the two corresponding sugar phosphates chains. They are 34A to complete one full cycle of the helix.
Fossils tell u if something has been there or not and u study it in some classes or jobs
Model two because it includes more organelles
