The structure of this is it has a double membrane with holes that allow some molecules to pass through.
What is the structure of the nucleus?
This structure has a double membrane with holes that allow some molecules to pass through.
What is the structure of the nucleus?
A section of DNA that affects traits
What is a gene?
phenotypic differences in organisms of the same species
What is the definition of variation?
an activity or behavior that is acquired by an organism through experience
What is learned behavior?
This structure has an outer membrane and a folded inner membrane.
What is the structure of mitochondria?
This structure has an outer membrane and a folded inner membrane.
What is the structure of mitochondria?
One of two copies of genetic code that form a gene.
What are alleles?
an organism’s ability to pass on its alleles to the next generation
What defines fitness?
the movement of an organism from one region to another
What is migration?
This sturcuture has two membranes that allow light to pass through them.
What is the structure of chloroplasts?
This structure has two membranes that allow light to pass through them.
What is the structure of chloroplasts?
Through experimentation, (blank) recognized that genes rely on two factors instead of one. This helped to explain why some traits could disappear from the first generation but reappear in the second generation.
What is true about Mendel?
the change in heritable traits that occurs in populations over time
What is the definition of evolution?
a symbiotic relationship between organisms in which both organisms benefit
What is mutualism?
