What is Melanin?
Element needed for bone health.
What is Calcium?
An organism's ability to survive and reproduce in its environment.
What is Fitness?

What is camouflage?
Continent where the human race first emerged.
What is Africa?
Essential vitamin needed to allow the kidneys to absorb heavy metals like Calcium and Phosphorus.
What is Vitamin D?
Evolutionary process whereby an organism becomes better able to live in its habitat by accumulating different traits that best suit their current environment.
What is an Adaptation?

What is Natural Selection?
The genetic sequence in DNA that codes for a specific characteristic or trait.

What is a Phenotype?
A skeletal condition caused by vitamin D deficiency, characterized by low Calcium absorption resulting in soft brittle bones.
What is Rickets?
Layer of skin where Vitamin D synthesis occurs.
What is the Epidermis?
Vitamin needed for DNA synthesis & infant development- extremely vulnerable to Solar Radiation.
What is Folate (Vitamin B)?
When an organism's adaptation to one environmental condition comes at the expense of another condition.
