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!
Answer:
a. Organism B is most closely related to organism A because the percentage of DNA similarity is 97%
b. Organism D and Organism A are the least closely related with a DNA similarity of 50%
c. Organism A and Organism B most likely share a common ancestor because there DNA is alomst identical leaving you to beleive that they are closly related.
I believe it's the mitochondrion.
Autotrophs are the producers, i.e. plants (they make their own food) so they gain their energy by converting light energy into chemical energy through the process of photosynthesis. Whereas heterotrophs (animals) cannot make their own food so they obtain nutrition through the consumption of autotrophs and other heterotrophs.
