We can not live with out CO2 because Co2 is need for plants to photosynthesise and produce energy for use to use later but if we have too much in our body it is VERY dangerous as it reacts with water to form carbonic acid and this would change the pH of your body and affect your enzymes which will kill you. Thats why we need to constantly breathe out. I dont know another one it could be proteins because too much protein can cause elephantitis and will kill you so anything you eat if potentially poisonus if you have too much of it.
This cannot be answered without knowing how much oxygen there is. ===== Each molecule of oxygen consists of two atoms of oxygen.
Yes it has two lone pairs that cannot be cancelled out
Chemical properties cannot be observed without changing its composition. ie: oxidation numbers Physical properties are properties such as melting point and boiling point. All that is needed to observe these are by placing the compound in a melting point apparatus etc.
Hemoglobin is the protein that, along with water, makes up a red blood cell. Hemoglobin is made from two substances, heme and globin. In order for hemoglobin synthesis to take place, two chains of globin must connect to one another. Without these chains, hemoglobin synthesis cannot happen.
You cannot mix two colors to make red, because red is a primary color, as are blue and yellow.

If you have a zebra danio in a tank, then there will be poisons created by the fish living, breathing, pooing etc in the water. These poisons will need to be removed otherwise the fish will die. There are two common methods of removing these poisons. One is to do regular daily water changes and the other is to use a cycled filter and less water changes. Please remember the basic rule though. "1 inch of fish needs a minimum of 1 gallon of water" so a zebra danio would need a minimum (nominal) 2 gallon tank to live in.
Violance and Order ....Two things which cannot be without the other
Cells must have two things: DNA and ribosomes. Without DNA, the cells cannot reproduce. Without ribosomes, proteins cannot be made or sent to other parts of the cell.
yes they can
unfortunately not.

You need at least one of the two kidneys which most people have. Kidney(s) "filter" the blood. Poisons build up in the blood without a kidney or a mechanical substitute.
One of them is food poisoning, and shigella poisoning
