Which of the following lists these structures from smallest to largest?

• DNA, chromosome, gene

• DNA, gene, chromosome

• gene, chromosome, DNA

• gene, DNA, chromosome

Which of the following correctly states the relationship between DNA, genes, and chromosomes?

• Chromosomes are made up of dna. DNA is made of small segments called genes

• DNA is made up of chromosomes. Chromosomes are made of small segment called genes

• Genes are made of DNA, A small segment of DNA is called a chromosome

• DNA, genes, and chromosomes aren't related to each other

• 46

• 23

• 92

• 12

What is true about the DNA in every body cell?

• All body cells have differenct DNA

• Cells have DNA just to make and run that particular cell

• Every body cell has identical DNA

• The DNA changes continuously

What is true about the offspring and parent DNA in an organism that undergoes asexual reproduction?

• The DNA is identical

• The offspring's DNA will be a mix of the parent and their siblings

• The offspring's DNA will be double the parent's DNA

• The offspring and parent will have completely different DNA

Which of the following is true?

• New body cells are produced through meiosis

• Mitosis produces sex cells

• Cells from meiosis are used in sexual reproduction

• Cells from mitosis have identical DNA

• a mathematical model

• a computer model

• a visual model

• a physical model

Which of the following is an advantage of asexual reproduction?

• The offspring are genetically identical

• The offspring have genetic diversity

• It takes longer than sexual reproduction

• The organism can reproduce fewer times

How are traits inherited in sexual reproduction?

• Males get their traits from the father, females get their traits from their mother

• Offspring get their traits from their mother only

• Offspring get half of their traits from each parent

• Offspring get new traits- it doesn't matter what traits their parents have.

What is a mutation?

• A new, identical strand of DNA

• A change in the DNA

• A DNA strand that is doubled

• A DNA strand without genes
