Why do cells carry out cellular respiration
vitfil [10]
<span>Plants and animals carry out cellular respiration, but only plants conduct photosynthesis. Cellular respiration is the process in which a cell uses oxygen to convert glucose, a simple sugar, into the energy-carrying molecule, adenosine triphosphate (ATP).

tyrosine kinase inhibitor binds and inhibits BTK. As a result of the experiment, you are able to elute BTK from the column, but
Sindrei [870]

Answer: It is because tyrosine kinases and BTK have similar solubilities

Explanation:

In column chromatography, components of a mixture are seperated based on their relative solubilities in two non-mixing phases.

In essence, tyrosine kinases and BTK are present in the eluate due to their similar solubility rates that arise from the similar chemical structure both possess (otherwise it would be impossible for the inhibitor meant for Tyrosine kinase to bind and also inhibits BTK)

Thus, the similar solubilities of both groups is the reason they could elute out of the column without being adsorped.

Answer:

The wavelength of the radio wave is 3.003 m.

The energy of the radio wave is 6.6194\times 10^{-26} J.

Explanation:

Frequency of the radio waves, ν = 99.9 MHz = 99.9\times 10^6 Hz

Wavelength and frequency are related to each other by realtion:

\lambda =\frac{c}{\nu }

\lambda = Wavelength of the wave

c = speed of the light

ν = Frequency of the wave

\lambda =\frac{3\times 10^8 m/s}{99.9\times 10^6 s^{-1}}=3.003 m

The wavelength of the radio wave is 3.003 m.

The energy of the electromagnetic wave is given by Planck's equation:

E=h\times \nu

h = Planck's constant = 6.626\times 10^{-34} Js

The energy of the radio wave with 99.9 MHz frequency will be:

E=6.626\times 10^{-34} Js\times 99.9\times 10^6 s^{-1}

E = 6.6194\times 10^{-26} J

The energy of the radio wave is 6.6194\times 10^{-26} J.
