<u>Answer</u>:
The nucleus is primarily stores most of the cell's DNA.
<u>Explanation</u>:
It is made up of two chains which coils around each other, together they form a helical structure tat further carries the genetic information, which will help in the development, functioning and also the growth and reproduction in all known organism and in viruses. The nucleus is stored in it and the nucleus has the genetic material. They are composed of the nucleotides, in which each nucleotide has four nitrogen. These nucleotides are together joined with covalent bond to each other. Together they have the biological information.
Hypothesis: I believe an increase in temperature would lead to a decrease in surface tension.
Here's why: As the temperature increases, the molecular interaction between the liquids molecules becomes weaker because the hydrogen bond is the main factor for association between two molecules. It is a very weak bond to begin with, so when the temperature increases, it just further weakens it.
Answer:
Any of a group of submicroscopic entities consisting of a single nucleic acid chain surrounded by a protein coat and capable of replication only within the cells of living organisms: many are pathogenic
