Chameleon Color Change and Vulture Feeding Habits

The video explains that chameleons do not change color by altering skin pigments, but through complex mechanisms involving nano salt crystals in their skin cells. These crystals refract light, and by adjusting their spacing, chameleons can change their color. Additionally, the video briefly discusses vultures' feeding habits, highlighting their preference for softer parts of a carcass.

What was the initial belief about how chameleons change their color?

• By altering their body temperature

• By changing the pigment in their skin

• By using external light sources

• By shedding their skin

What do chameleons use to change their color?

• Reflective scales

• Micro pigments

• Nano salt crystals

• Light-absorbing cells

How do chameleons adjust their color appearance?

• By altering their skin texture

• By changing the distance between nano salt crystals

• By increasing their body temperature

• By using sunlight

What is the result of changing the distance between the nano salt crystals in chameleons?

• It makes them invisible

• It increases their body size

• It enhances their speed

• It changes the wavelength of light refracted

Why do vultures target the softest parts of a carcass?

• Because they are the most nutritious

• Due to the absence of larger scavengers

• To avoid competition

• To mark their territory
