Answer:
<em>In order to ensure consistent membrane fluidity</em>
Explanation:
<h3>
Cold Blooded Animals</h3>
Cold-blooded animals rely on the temperature of the surrounding environment to maintain its internal temperature, their blood is not cold. Their body temperature fluctuates, based on the external temperature of the environment. If it is 30 °F outside, their body temperature will eventually normalize to 30 °F, as well. If it eventually rises to 120 °F,
their body temperature will follow the same pattern to 120 °F.
<h3>Membrane fluidity</h3>
The cell membrane of cold-blooded animals contains cholesterol, which acts as a shield for the membrane. Membrane fluidity is enhanced by temperature, as the temperature increases membrane fluidity increases and it decreases when the temperature goes down.
<em>Most cold-blooded animals adjust their feeding habit to contain more </em><em>unsaturated fats</em><em> from plants. This helps them to maintain their </em><em>motor coordination and membrane </em><em> fluidity during the long winter</em>
Cold-blooded animals modulate the fatty acid composition of their membrane to stabilize their membrane fluidity
Answer:
- <u>Because the atoms of the elements only emit some specific frequencies of light.</u>
Explanation:
The spectra lines are the result of the emission of different frequencies of light (electromagnetic radiation) from the atoms of an element when some electrons decay from an upper (excited) energy level to a lower energy level.
The fact that certain regions do not show lines means that the spectrum is not continuos but discrete. This is, only some specific frequencies of light are emitted.
The frequency of the light is related with the energy per the Einstein-Planck´s equation:
Where h is Planck's constant and f is the frequency of the electromagnetic wave (light).
Thus, it is concluded that only photons with certain specific energies are emitted.
This is what is meant when you say that the light has dual behavior: as wave and as particle: the light is emitted in packages named quanta.
The emission spectrum is a demostration of the discrete (quantized) nature of the light.
The answer is 4.41x10^1 m.
Explanation:
You would use this formula to calculate it
λ = C/f
Where,
λ (Lambda) = Wavelength in meters
c = Speed of Light (299,792,458 m/s)
f = Frequency
So we have the frequency, 68 Hz, and we have the speed of light. Now we put it into the equation and it will look like this:
λ= (299,792,458 m/s) / (68 Hz)
λ= 4.41x10^1
