Answer: The correct answer for the blank is- Replication.
DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called as DNA polymerase.
The two strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. In other words, the two strands are broken apart and attract new nucleotide bases to synthesize a new and complete strand of DNA.
This is done by DNA polymerase according to Watson and Crick base pairing ( A pairs to T, G pairs to C)
Answer
0.001339 liter
Explanation:
It is given that radius = 4 cm =0.04 m
volume of sphere 

It is given that hose delivers five liters per minute
So the water flows through sphere per minute is given by 5×2.674×
=0.001339 liters
Answer:
0.91 J
Explanation:
The kinetic energy of an object is given by

where
m is the mass of the object
v is its speed
For the lemming in this problem, when he jumps, we have:
m = 0.0780 kg is the mass
v = 4.84 m/s is the speed
Substituting into the equation, we find:

Answer:
Iron
Explanation: It is by mass the most common element on Earth, right in front of oxygen, forming much of Earth's outer and inner core.
