Answer: They are not regulated by contact inhibition.
Explanation:
Contact inhibition is a form of controlling cells. Cancer doesn't have contact inhibition, which is one of the reasons why it spirals out of place so easily.
The following statement is false. This is because a frameshift mutation is caused by either insertions or deletions of a number of nucleotides in the sequence of DNA. This type of mutation alters the reading frame of the DNA sequences and changes all the amino acids in the protein after the point of mutation.
A covalent bond is a bond between two non-metals where they share a pair of electrons, like carbon dioxide (CO2).
An Ionic bonds a bond between metal and a nonmetal where the metal loses electron and becomes positively charged ion (cation) and non-metal gains electrons (from the metal) and becomes negatively charged ion (anion)
The metallic bond <span>is the sharing of many detached electrons (delocalised electrons) between many positive ions in which the electrons freely and randomly flow around (in the material). +NOTE+ delocalised electrons are needed in order for a substance to be able to conduct electricity.
Crystalline bond is you wanted.

Answer:
Water pollution as a result of fertilizer runoff from farms is harmful because it initially changes the chemical composition of nearby streams and lakes !
Explanation:
A<span>denine goes with thymine and guanine goes with cytosine.
So A-T, G-C. These are free floating DNA nucleobases that pair up with one set of a DNA molecule when it is "unzipped". </span>
