In the model, a codon is identified as part of the mRNA strand. A codon is a series of three nucleotides on mRNA that codes for an amino acid.
mRNA
This is one form of RNA that serves as a template for protein synthesis. It is transcribed from DNA and then translated at ribosomes to produce a protein.
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
A covalent bond is a bond between 2 non-metals (sharing of electrons between atoms), where ionic is between a metal and a non-metal (the transfer of electrons). Standard covalent bonds are usually weaker then ionic bonds.
Covalent - Hydrogen + Chlorine = Hydrogen Chloride (HCl)
Ionic - Sodium + Chlorine = Sodium Chloride (NaCl)
Answer:
Limiting Reactant
Explanation:
Observe the answer choices:
A) Limiting Reactant; a limiting reactant, as can be seen from the name, is the reactant that <em>limits</em> the amount of products can be made. This is because the reaction can only go on if there is enough reactants. However, the limiting reactant is the one that will run out first, so it's going to be completely consumed.
B) Reactant; a reactant is the thing that is being consumed in a reaction. However, reactants aren't always completely consumed. There's something called an excess reactant, which is essentially the opposite of a limiting reactant in that when the limiting reactant is used up, there's still some excess reactant left - because it's in <em>excess</em> / there's more than enough remaining. So, this is incorrect.
C) Products are the ones that are created during the chemical reaction, so they aren't consumed in any way. Thus, this is wrong.
The answer is limiting reactant.
Hope this helps!
