O The Interlocking bricks are the chromosomes.
O Each structure is a gene.
The manual is a chromosome,
Each set of instructions is a protein.
The manual is a chromosome.
What determines a trait of an organism?
O the number of dominant alleles
O the number of copies of the gen
O the combination of its alleles
O its phenotype
The combination of its alleles determines a trait of an organism.
Which statement is true of all proteins? (1 point)
O Their structure is related to their function.
O Their main function is to cause mutations.
O They carry oxygen in human blood.
O They are created by mutations in DNA.
The statement that is true of all proteins is: Their structure is related to their function.
What is the main benefit of genetic biodiversity? (1 point)
O Genetic biodiversity helps individuals produce more offspring.
O Genetic biodiversity helps individuals compete with each other.
O Genetic biodiversity helps populations adapt to environmental changes.
O Genetic biodiversity helps populations avoid predators.
The main benefit of genetic biodiversity is that it helps populations adapt to environmental changes.
Which statement is true? (1 point)
O Neutral mutations occur when a mutation is found in a DNA region and results in a harmful disease.
O Neutral mutations occur when a mutation is found in a DNA region that codes for proteins.
Neutral mutations occur when a mutation in a DNA region provides an advantage that helps the organism survive. O
O Neutral mutations occur when a mutation in a DNA region results in the same sequence as the original.
The statement that is true is: Neutral mutations occur when a mutation in a DNA region results in the same sequence as the original.

O Genetic factors caused the differences in flower color.
O Environmental conditions caused the differences in flower color.
O Genetic factors caused environmental changes that caused the differences in flower color.
