7th Science Asexual and Sexual Reproduction Quiz Review

A population of ladybugs was once mostly red with black spots and is now a mix of colors as shown in the image. Which statement best explains the variety of colors seen in the ladybug population?

• Asexual reproduction required new ladybugs to fly in from another location.

• Sexual reproduction produced genetic variation which changed the population over time.

• Sexual reproduction produced identical organisms which caused the population to diversify.

• Asexual reproduction produced too many organisms, therefore some changed color to become new species.

A new disease has decreased wheat crop production on a farm. In order to increase crop production again, which step should the farmer take?

• rotate different types of crops planted in the same area as the wheat crops
