How do the flowers of wind-pollinated plants differ from those of insect-pollinated plants?
What will be an ideal response?
Wind-pollinated plants do not need to attract or reward an insect pollinator, and are thus not large, colorful, or fragrant. Petals are reduced in size, and pollen is especially abundant since it must be carried by the wind to reach its destination.

Type S Streptococcus pneumoniae bacterium is lethal and will kill its host. If heat inactivated the S strain dies and becomes nonlethal.

A. The R strain would be transformed into the virulent S strain and kill the host. B. The R strain would be transformed into the virulent S strain and not affect the host. C. The S strain would be transformed into the nonvirulent R strain and kill the host. D. The S strain would be transformed into the nonvirulent R strain and not affect the host. E. Neither the S nor the R strain would change.
