The nervous system and the circulatory system
Explanation:
Before mitosis, the chromosomes are copied. They then coil up, and each chromosome looks like a letter X in the nucleus of the cell. The chromosomes now consist of two sister chromatids. Mitosis separates these chromatids, so that each new cell has a copy of every chromosome
He noticed that the outlines of the continents looked like they could fit together similar to puzzle pieces

The work function has the formula
E = h v
where
E is the energy
h is the constant
v is the frequency
Since the given is wavelength, we use the relationship between frequency and wavelength
v = c / λ
where
c is the speed of light
<span>λ is the wavelength
</span>
So.
E = h c / <span>λ
h = E</span><span>λ / c = 1.25 eV (475x10-9m) / (3x10^8 m/s)
h = 1.9792 x 10^-15
The work function is:
E = 1.9792 x 10-15 v
