Every cell has a nucleus unless it is RNA which is involved with DNA movement
<u>Answer:</u> The product side must be 
<u>Explanation:</u>
Single displacement reaction is defined as the reaction in which more reactive metal displaces a less reactive metal from its chemical reaction.

Metal C is more reactive than metal A.
The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.
When zinc metal reacts with hydrochloric acid, it leads to the production of zinc chloride and hydrogen gas. The chemical reaction follows:

<u>On reactant side:</u>
Number of zinc atoms = 1
Number of hydrogen atoms = 2
Number of chlorine atoms = 2
<u>On product side:</u>
Number of zinc atoms = 1
Number of hydrogen atoms = 2
Number of chlorine atoms = 2
Hence, the product side must be 
Answer:
Genetic disorders is an illness caused by abnormalities in genes or chromosomes.The cells of all mammals contain approximately the same amount of deoxyribonucleic acid (DNA).
Explanation:
Mammals are affected through an increase in the number of cells and not in their size.
Answer:
The molecule has two chiral carbons
Explanation:
i hope its the right answer
Answer :
Incorrect
Explanation : In the given solution set of Ax = b;
is set of all vectors to form w=
p +

here

is is any solution of the equation Ax = 0;
this stands to be incorrect, as the correct would only exists when some vector
p is found to be like this
Ap=b
