Pairs of thread-like molecules, which live in a cell's nucleus, and carry genetic information are called

• ribosomes
• mitosis
• DNA
• meiosis

Made of DNA, this is the basic physical and functional unit of heredity

• chromosomes
• nucleus
• nucleic acid
• mitochondria

Which of the following defines heredity?

• The manipulated changing of a trait in an organism
• the study of how characteristics are passed from parent to offspring
• the ability of organisms to adapt to their environment
• the passage of genetic instructions from one generation to the next

Four puppies have different hair color than the mother, which is responsible for the variety of hair color?

• asexual reproduction
• binary fission
• regeneration
• sexual reproduction

Which characteristic is true of sexual reproduction but not of asexual reproduction?

• Produces new individuals
• Produces diverse offspring
• Involves a form of cell division
• Involves one or more parents

Which of the following is NOT true of asexual reproduction?

• allows for rapid population increases
• occurs commonly among single-celled animals
• causes a population to have more genetic variety
• can be used along with some organisms along with sexual reproduction

If a starfish is cut in half and grows into two new starfish, what is a characteristic of this type of reproduction?

• New traits will be produced in the new organism
• The genetic material will be identical
• The offspring will be genetically different from the parent
• Egg and sperm cells are responsible for the new growth

Which of the following is always true of animals that are products of sexual reproduction?
