Because the nucleic acid is damaged, so how is it going to produce anything without a miracle?

Nucleic acids are the main information-carrying molecules of the cell<span>, and, by directing the process of </span>protein synthesis<span>, they determine the inherited characteristics of every living thing.

So if that is damaged then, of course, you would be out of luck.

Consider a transition of the electron in the hydrogen atom from n=3 to n=7.

kow [346]

<u>Answer:</u>

<u>For a:</u> The wavelength of light is $1.005\times 10^{-6}m$

<u>For b:</u> The light is getting absorbed

<u>Explanation:</u>

<u>For a:</u>

To calculate the wavelength of light, we use Rydberg's Equation:

$\frac{1}{\lambda}=R_H\left(\frac{1}{n_i^2}-\frac{1}{n_f^2} \right )$

Where,

$\lambda$ = Wavelength of radiation

$R_H$ = Rydberg's Constant = $1.097\times 10^7m^{-1}$

$n_f$ = Higher energy level = 7

$n_i$ = Lower energy level = 3

Putting the values in above equation, we get:

$\frac{1}{\lambda }=1.097\times 10^7m^{-1}\left(\frac{1}{3^2}-\frac{1}{7^2} \right )\\\\\lambda =1.005\times 10^{-6}m$

Hence, the wavelength of light is $1.005\times 10^{-6}m$

<u>For b:</u>

There are two ways in which electrons can transition between energy levels:

<u>Absorption spectra:</u> This type of spectra is seen when an electron jumps from lower energy level to higher energy level. In this process, energy is absorbed.
<u>Emission spectra:</u> This type of spectra is seen when an electron jumps from higher energy level to lower energy level. In this process, energy is released in the form of photons.

As, the electron jumps from lower energy level to higher energy level. The wavelength is getting absorbed.

What patterns in the rock layer fossils helped you identify an extinction?

Dafna11 [192]

Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction
