Answer:
There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.
Hope this helps :)
The frequency of radiation : 1.2 x 10¹⁵ Hz
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as

Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
<h3>f = c / λ
</h3>
c = speed of light
= 3.10⁸ m/s
λ = wavelength
Wavelength-λ is 2.51 x 10⁻⁷m
The frequency :

The answer is A. Gravity
The gravitioal force that an object exerted will increase as the object is increasing in sizre.
Which means that if object A has two-times more mass than object B, Object A will has twice as much gravitational pull if compared to object B.
