Answer:

the messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell

Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction: Fe + O2
Ber [7]

ANSWER

The correct answer is A

<u>EXPLANATION</u>

From the equation Fe + O_2 \rightarrow Fe_2O_3


<u>L.H.S.</u>               


Fe = 1                        

O  =2      

                 

<u> R.H.S</u>

Fe =2


O  =3

Now, let try to balance the oxygen atoms first,

To do this, we know the Least Common Multiples of 2 and 3 is 6


To get 6 atoms of oxygen at L.H.S  multiply 2 by 3 and on the R.H.S, multiply 3 by 2



L.H.S.                        

O=2\times3=6      


R.H.S

O=3\times2=6  


This means that, 3 should be in front of O_2 at the L.H.S and 2 should come before Fe_2O_3 in the R.H.S of the equation


Now, we have


L.H.S.                        


Fe = 1                          

O  =  6                        

<u>R.H.S</u>

Fe =4

O  =6

The equation is still not balanced since Fe is not balance

 

The Least Common Multiple of  1 and 4 is 4

Which means that we need to multiply 1 by 4 at the L.H.S and 4 by 1 at the R.H.S



L.H.S.                        

Fe=1\times4=4      


R.H.S

Fe=4\times1=4  


We now, have



<u>L.H.S.   </u>                    

Fe= 4                          

O=6                        


<u>R.H.S</u>

Fe =4

O=6

Hence the balanced equation is

4Fe +3O_2\rightarrow 2Fe_2O_3

What types of specimens were you able to view under each of the microscopes in the microscope activity? How did the specimen vie
Lana71 [14]

Under the dissecting microscope I was able to view the surfaces of specimens such as a feather, insect, and leaf.

Under the compound microscope I was able to view a leaf, blood, and algae. I was able to observe the surface of the specimens in greater detail then I was able to view the surfaces under the dissecting microscope. For an example under the compound light microscope I was able to view the leaves surface which contained multiple lines that intertwined into each other and rectangular chambers of green dots. But under the dissecting microscope I was only able to view the surface of the leaf which consisted of thin white cracks in the leaf.

Under the scanning electron I was able to view the internal structure of the following specimens: a leaf, blood, and algae.  

Under the transmission electron I was able to view a more in depth internal structure of the following specimens:a leaf, blood, and algae. I was able to observe the intern

al structures of the specimens in greater detail then I was able to view the internal structures under the scanning microscope. For an example under the TEM I was able to study the internal structure of a leaf which consisted of long thick and thin black and gray lines coated with black rectangles and tiny dots littering he perimeter of what looks to be the internal structure of the leaf. But with the SEM I was only able to view the first layer of the leaf's internal structure which consisted of mushroom like figures surrounded be compound and single molecules.
