It can utilize even low wind speeds to produce electricity.
During DNA replication, the two strands separate as the hydrogen bonds connecting the parent strands are broken by an enzyme called helicase. In the DNA molecule (double strand) complementary bases are joined by hydrogen bonds; that is; Adenine paired to thyamine and guanine to cytosine; during replication the enzyme helicase separates the double helix by breaking the hydrogen bonds between the complementary bases.
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,

Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,

Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,

If V = 2V and p = 2P
Then,


Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
The Red Blood Corpuscles in the blood take up the oxygen to supply it to different cells in the body. They do not have a nucleus to carry much oxygen and to go through the thinnest capillaries and narrow spaces. They do not have mitochondria so that they do not use up the oxygen or energy for themselves.
