Answer: Change in a single nitrogen base in the DNA sequence will not have any significant effect on the organism.
So A
Explanation:
This is known as point mutation and it does not have any significant change in the protein and it is least harmful type of DNA mutation.
solution:
the change in the boiling point is given as,
dTbp =2.30°c
elevation constant for the solvent is given by,
kb=0.512°c/m
= 4.49m
Answer:
Option (2) 2
Explanation:
NO3- + 4H+ + Pb → Pb2+ + NO2 + 2H2O
The equation above can be balance as follow:
There are 3 atoms of the left side and a total of 4 atoms on the right side. It can be balance by putting 2 in front NO3- and 2 in front of NO2 as shown below:
2NO3- + 4H+ + Pb → Pb2+ + 2NO2 + 2H2O
Now the equation is balanced.
The coefficient of NO2 is 2
Answer:
hey :)
your answer is D.
Explanation:
To find density, you must divide mass and volume.
8 divided by 4 is 2
6 divided by 6 is 0
4 divided by 2 is 2
hope i helped any :))
My view point is that i disagree and that the rules are completely different
