Covalent bonds are formed when two atoms are able to <em>share</em> electrons.
Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.
<u>Covalent bonds:</u>
- Have a definite shape.
- Have a low melting point.
- At room temperature they are in a liquid or gas.
- They occur between two non-metals.
<u>Ionic bonds:</u>
- Have no definite shape.
- Have a high melting point.
- At room temperature they are solid.
- They occur between a metal and a nonmetal.
Answer:
AG or B
Explanation:
i didnt understand what ich mean
but the explanation is that it must have two chromosomes before meiosis so will undergo meiosis to give one set either B or AG
In general for everyone, these are the most likely group of people i've chosen mature; grandparents(grandma,granddad), parents (mom,dad), your teacher.
Answer:
You could check the pH!
Explanation:
This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.
So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.
The nucleotides are bonded together via hydrogen bonds making it easy for the dna to be split in half and replicated
