DNA needs to replicate before cells divide to give the complete set of genetic instructions to its daughter cells, (or ensures that each new cell inherits all of the genetic traits of the parent cell).

Hope this helps! :D

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

EXPLANATION

From the equation $Fe + O_2 \rightarrow Fe_2O_3$

L.H.S.

Fe = 1

O =2

R.H.S

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

R.H.S

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

L.H.S.

Fe= 4

O=6

R.H.S

Fe =4

O=6

Hence the balanced equation is

$4Fe +3O_2\rightarrow 2Fe_2O_3$

Bone marrow aspiration symptom alerts the health care provider that this child might have acute lymphoblastic leukemia (all)

Acute lymphocytic leukemia (ALL) is a kind of blood and bone marrow malignancy. Blood cells are generated in the spongy tissue inside the bones.
Acute lymphocytic leukemia gets its name from the fact that it advances quickly and produces immature blood cells rather than mature ones.
Acute lymphoblastic leukemia in children is more frequent than other cancers, however it is curable in a significant portion of cases. Adult survival rates are lower, although they are rising.
ALL has a 5-year relative survival rate of 68.8%. 90 percent of children and 30 to 40 percent of adults are included in the statistics, respectively.
