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.
Chloroform cannot be directly converted to ethanol. These two compounds have different chemical structures and cannot be interconverted without breaking down and re-synthesizing starting from a different molecule.
This cannot be answered without knowing how much oxygen there is. ===== Each molecule of oxygen consists of two atoms of oxygen.
Oxidation cannot occur without a reduction reaction happening simultaneously. In a redox reaction, electrons are transferred between two species: one is oxidized (loses electrons) and one is reduced (gains electrons). This electron transfer process is essential for oxidation to take place.
Two substances that cannot be broken down by chemical change are elements and compounds. Elements are fundamental building blocks of matter that cannot be broken down into simpler substances by chemical reactions. Compounds are made up of two or more different elements chemically bonded together in fixed ratios, and they also cannot be broken down into simpler substances by chemical reactions.
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.
no,you cannot live without water for two weeks because if you do not drink water within 72 hours then your kidney will fail.
No, two 16 year olds cannot legally live together without their parents or legal guardians unless they are emancipated. In most jurisdictions, minors under the age of 18 are not considered capable of entering into legally binding contracts like a lease agreement for housing.
you cannot do this
Well, there are two types of dung beetles. One type eats dung and can live on it without eating anything else. The other group eats fruits, etc and not dung. No, some dung beetles cannot live without poo of animals preferably herbivores.
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.
A cockroach can live for about one to two weeks without its head. This is because it has a decentralized nervous system, allowing it to function without the need for a brain. The cockroach can survive without its head until starvation eventually leads to death. It can drink water through its body, but it cannot eat without its mouth.
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.
You cannot
One of them is food poisoning, and shigella poisoning
gall bladder
yes they can
