Answer:

This phenomenon is known as <em>Refraction.</em>

Explanation:

Light waves change speed when they pass across the boundary between two substances with a different density, such as air and glass. This causes them to change direction, an effect called refraction.

At the boundary between two transparent substances:

the light slows down going into a denser substance, and the ray bends towards the normal

the light speeds up going into a less dense substance, and the ray bends away from the normal

olya-2409 [2.1K]
<h3><u>Answer;</u></h3>

b). Activation of an upstream guanine nucleotide exchange factor

<h3><u>Explanation</u>;</h3>
  • <em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
  • The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.
