Contagious diseases are spread by contact, while infectious diseases are spread by infectious agents. Something "contagious" is by default "infectious" because contact exposed you to the infectious agent, but something infectious isn't always contagious.
The DNA of a human cell can be cut and rearranged by using Enzymes. To cut DNA into smaller segments, enzyme nucleases are used. They do this by taking the phsophodiester bonds through hydrolysis and catalyzing it. when these enzymes comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the molecule.
The force that attracts all matter to each other is gravity, i believe.
The material that makes up the membrane cell is the phospholipids, cholesterol, proteins, and carbohydrates.
You need to know 1) How much kinetic energy it absorbed before it broke.
2) What materials are able to scratch it.
3) Its mass.
