What is the difference between the purines and the pyrimidines?

1 answer:

3 0

They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.

Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.

Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.

Un diapasón vibra a 140 [Hz] y la onda emitida por él se propaga con una rapidez de 340 m/s.Considerando lo anterior, se puede a

Gnom [1K]

The question is: A tuning fork vibrates at 140 [Hz] and the wave emitted by it propagates with a speed of 340 m / s. Considering the above, it can be correctly stated that the wavelength of the wave emitted by the tuning fork is

Answer: Wavelength of the wave emitted by the tuning fork is 2.43 m.

Explanation:

Given: Frequency = 140 Hz

Speed = 340 m/s

wavelength = ?

Formula used to calculate the wavelength is as follows.

$\lambda = \frac{v}{f}$

where,

$\lambda$ = wavelength

v = speed

f = frequency

Substitute the values into above formula.

$\lambda = \frac{v}{f}\\= \frac{340 m/s}{140 Hz} (1 Hz = 1 s^{-1})\\= 2.43 m$

Thus, we can conclude that wavelength of the wave emitted by the tuning fork is 2.43 m.

The luxury liner Queen Elizabeth 2 has a diesel-electric powerplant with a maximum power of 84 MW at a cruising speed of 35.0 kn

frosja888 [35]

Answer:

$F = 4669.201\,kN$

Explanation:

Maximum speed is get at maximum power. Let assume that ship travels at constant speed, the expression for power is equal to:

$\dot W = F\cdot v$

Where $F$ and $v$ are the forward force and speed of ship measured in newtons and meters per second, respectively.

The forward force can be determined by clearing it in the expression described above:

$F = \frac{\dot W}{v}$

$F = \frac{84\times 10^{3}\,kW}{(35\,knots)\cdot \left(\frac{0.514\,\frac{m}{s} }{1\,knot} \right)}$

$F = 4669.201\,kN$

Which describes why the sun is a renewable resource? The sun creates biomass. The sun is continuously releasing energy. The sun

Fynjy0 [20]

Renewable source means that it can never run out or run out in a long time. In this case the sun is expected to shine for about five billion years because of the high amount of hydrogen that is stored in its core. So the answer should be "The sun is continuously releasing energy". This answer is the best because there are many other renewable resources on earth that can cause pollution.
