DNA
What 3 factors does a seed need for germination?
Warmth, oxygen, water
Name one way the human body stays cool
Sweat, hairs lying down, blood to surface of skin
What is 1 advantage of sexual reproduction?
Produces genetic variation, less competition (well distributed), internal fertilisation has higher change of offspring survival
