Women ages 30 through 65 can then be screened every 5 years with Pap and HPV cotesting or every 3 years with a Pap test alone. The guidelines also note that women with certain risk factors may need to have more frequent screening or to continue screening beyond age 65.
Petioles support leaf growth. Also called the leaf stalk, the petiole is actually an extension of the leaf in certain plants. It is the structure that connects the leaf to the stem or trunk of most vascular plants.
Although the filament may be thought of as just a simple stalk, it actually has a very important function. The filament is responsible for getting the pollen-bearing anther as close to the top of the pistil as possible because this is the location where pollen will be transferred to the female reproductive organ.
