D. The cell is prokaryotic because it does not have any membrane-bound organelles.
Explanation:
The difference between eukaryotic and prokaryotic cells are that the eukaryotic cells have a nucleus and they have membrane-bound organelles, and prokaryotic cells don't.
Hope this Helps!
The answer would be:
C. The abuse will happen again regardless of how sorry the abuser seems to feel.
Hope this helps! :)
It would protect best against C) Alpha radiation, as Beta radiation is stopped by lighter metals such as aluminium, and Gamma radiation can only be stopped by heavier metals such as lead.
Explanation:
(a)
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Wavelength = 505 nm
Also, 1 m =
nm
So,
Wavelength =
m
Thus, Frequency is:
(b)
Also,
Where,
h is Plank's constant having value
c is the speed of light having value
So,


(c)
Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.
In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:
Red , Orange, Yellow, Green, Blue, Indigo, Violet
Increasing wavelength is the opposite trend. Thus, The longest visible wavelength is red and the shortest is violet.
Explanation: Ca generally loses two electrons from its outer shell to form a Ca2+ ion.
