Reproduction Review

Some one-celled organisms can reproduce by the process of

• Hormone Secretion
• Metamorphosis
• Fertilization
• Cell Division

Asexually produced offspring are genetically

• Identical to the parent
• Different from the parent
• Different from each other
• Formed by two parents

In a one-celled organism, cell division is responsible for

• Growth, maintenance and development
• Sexual Reproduction
• Asexual Reproduction
• Production of sex cells

Compared to the amount of hereditary information in a human body cell, how much hereditary information is contained in a human sex cell?

• One quarter
• One half
• The same amount
• Twice the amount

What advantage does a species that reproduces sexually have over a species that reproduces asexually?

• There is greater variation among the offspring
• The offspring are identical to each other
• onlyu one parent is needed for reproduction
• No sex cells are needed for reproduction

The vast variety of different traits found in humans results from

• Intensive training and education in 7^th grade science (orange team)
• Sexual reproduction and mutations
• Exercise and conditioning
• Birth defects and recessive genes
