As white light passes through a prism, the light is separated into the different colours of light that we see and this is called the visible spectrum. Each colour of light has a different wavelength. The wavelength is inversely proportional to the energy of that light. As the wavelength increases, the energy decreases and vice-versa. The relationship is:

E = h/λ, E is energy, h is Planck's constant, and λ is the wavelength.

Therefore, the answer is B) different amounts of energy in white light.

Cloud [144]

Answer:

C. Both A and B describe errors in the statement.

Explanation:

In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.

- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.

- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).

According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.

Lysine (positively charged amino acid)

It is present on the outside of a globular protien.

Explanation:

Formula of lysine:

C6H14N2O2

Globular proteins are folded such that their tertiary structure consists of the polar, or hydrophilic, amino acids arranged on the outside and the nonpolar, or hydrophobic, amino acids on the inside of the three-dimensional shape. This arrangement is responsible for the solubility of globular proteins in water.

As lysine is a positively charged polar / hydrophilic amino acid , it is arranged on the outside of the globular protien.
