what does it mean to say that two different species of organisms are closely related?
a. they live in the same habitat.
b. they have the same preferences in diet.
c. they have the same parents.
d. they have a common evolutionary ancestor.

Dna. we have heard that we are a product of our dna. but where is it? how do we "get" our dna? it is passed to us, from our parents, but in what form? several vocabulary words associated with inheritance are used interchangeably and sometimes, incorrectly. let's see if you can clear this up for someone just learning about inheritance and cell structure.
