Answer:
The promoter
Explanation:
The promoter region is the region of DNA sequence which the RNA polymer binds to to initiate transcription. In the archae and eukaryotes, the core portion of the promoter region is called the TATA BOX. The promoter region is also located upstream of the DNA and can about a 100-1000 base pairs long.
<span>Electrons are not distributed or shared same because of oxyen that is being attracted strongly. Water is a "polar" atom, implying that there is an uneven sharing of electron in its thickness. Water has an incomplete negative charge ( ) close to the oxygen molecule due the unshared sets of electrons, and fractional positive charges ( ) close to the hydrogen particle</span>
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.
A control is used to establish a baseline in an experiment.
hope it hepls
