Answer: In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. ... This enables better survival and reproduction compared with other members of the species, leading to evolution.Adaptations are the result of evolution. ... Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation. For example, imagine a bird species.

Answer:
The conformational change in the G protein coupled receptor.
Explanation:
GPCR or the G protein-coupled receptor is one of the largest group of receptors in the eukaryotes.
The GPCR are seven-transmembrane receptors which are attached to the G proteins. The binding of the stimulus signalling molecules to the GPCR causes a conformation change in the GPCR. This conformational change in the GPCR disrupts the interaction between the G proteins and GPCR.
The change in the conformation of the receptor causes the dissociation of the G proteins and which can interact with other molecules of the membrane.
Thus, the conformation changes in the GPCR are the correct answer.

Explanation:
"When your body is injured in some way or something else is wrong, your nerves (cells that help your body send and receive information) send millions of messages to your brain about what's going on. Your brain then makes you feel pain." -Why Do I Have Pain? (for Kids) - Nemours KidsHealth
I didn't write that, but I gave credit to whoever did.
Answer: Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
