Answer:
The growth of forests.
Explanation:
The Carboniferous Period occurred around 300 million years ago
It is named because many coal beds were formed during this era.
During, the Carboniferous period the first extensive forests appeared on Earth. The expansive growth of these forests removed huge amounts of carbon dioxide from the atmosphere.
Answer:
The value is 
Explanation:
From the question we are told that
The emitted frequency increased by 
Let assume that the initial value of the emitted frequency is

Hence new frequency will be 
Generally from Doppler shift equation we have that
![f_1 = [\frac{ v \pm v_o}{v \pm + v_s } ] f](https://tex.z-dn.net/?f=f_1%20%3D%20%20%5B%5Cfrac%7B%20v%20%5Cpm%20v_o%7D%7Bv%20%5Cpm%20%2B%20v_s%20%7D%20%5D%20f)
Here v is the speed of sound with value 
is the velocity of the sound source which is
because it started from rest
is the observer velocity So
Generally given that the observer id moving towards the source, the Doppler frequency becomes
=>
=> 
Answer:
Actin.
Arp2/3.
Collagen.
Coronin.
Dystrphin.
Elastin.

Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
Explanation:
Answer:
For this given plane monochromatic electromagnetic wave with wavelength λ=598 nm, the wavenumber is
.
Explanation:
For a plane electromagnetic wave we have that the electrical and magnetic field are:

In this case we have the data for the magnetic field. We are told that the magnetic field in a plane electromagnetic wave with wavelength λ=598 nm, propagating in a vacuum in the z direction (
) is described by

(
are the unit vectors in the x,y,z directions respectively)
The wavenumber k is a measure of the spatial frequency of the wave, is defined as the number of radians per unit distance:

where λ is the wavelength
So we get that

The wavenumber is
.
what? I guess:
- practice different habits. If you fail don't give up.
- don't always trust people, some are not what they seem.
this question doesn't make any sense...
