Which substance is completely consumed in a chemical reaction?
Rudiy27

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!

Explain why a signal cascade can be useful in certain cell processes
natima [27]
A signal cascade is a series of chemical reactions which are triggered by a stimulus acting on a receptor that is then transduced to the intracellular space through second messengers. Finally, effector molecules receive the signal causing a cellular reaction to the initial stimulus. A signal cascade is very useful because it facilitates and accelerates the communication between cells that could be in different parts of a living organism. This communication is vital for cell processes in complex multicellular organisms.

T: Parasites rarely kill their hosts right. Instead they keep them alive as long as needed. In fact, the best parasites never ac
Schach [20]

Parasites would want to keep their hosts alive because they cannot survive without one. Without a host, parasites will die off, meaning that they wouldn’t want to kill off their hosts, after all, that would kill them too.
