talk to your doctor about the risks and benefits of taking naproxen if you are 65 years of age or older. Older adults should usually take lower doses of naproxen for short periods of time because higher doses used regularly may not be more effective and are more likely to cause serious side effects. if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking naproxen.
A: Although sexual reproduction is a more common method of reproduction among animals, a few species, such as starfish and sea anemones, produce offspring via asexual reproduction. Asexual reproduction, in contrast to sexual reproduction, does not require the mating of two parents to produce an offspring.
The asexual form, or sporophyte, is represented by the commonly known and cultivated fern plant, and is diploid (2N). Sporophytes can reproduce either by vegetative cloning via their rhizomes or through spore formation. The prothallia are equipped with multiple antheridia (male reproductive organs) and archegonia (female reproductive organs). As heterosporous plants, the fern's antheridium produces free-swimming sperm and its archegonium produces eggs. The products of their unions are zygotes, and fertilization occurs when the sperm swim through an opening (operculum) from each antheridium along a thin film of water to the neck of each archegonium.
