Which types of faces might we perceive as attractive?

According to research studies, attractive faces are those that maintain harmony, asymmetry and proportionality of nature.

Explanation:

Our human eye perceives the harmonious, balanced as something beautiful or cute, which presents the same measurements on both sides (symmetrical).

Although art challenged this quality of the human eye through subrealistic techniques.

Temperature, activators, pH, and inhibitors

How does temperature affect enzymes?
Proteins change shape as temperature changes; the new shape could potientially mess up the enzyme so it doesn't work

How does activators affect enzymes?
They make enzymes work harder and faster

How does the pH level affect enzymes?
Enzymes can only function within a narrow pH range

How does inhibitors affect enzymes?
They are the opposite of activators and slow down or even stop the activity of the enzyme. Inhibitors often bond to the protein and change its shape, causing it not to work.
