DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic...

Seed saving is the preserving of seeds from mature vegetables, herbs, and flowers used in subsequent years along with bulbs and tubers. Home gardeners have saved seeds for generations and the practice is now becoming common with organic farmers as well as permaculturists. Growers will clone plants so as not to produce seeds keeping the plant “true to type” to the parent plant. True to...

Variable bushy feather star Comaster Schlegelii

The Variable bushy feather star is commonly found concealed on shallow water reefs in the western Pacific Ocean. The parts that will be most often seen are the fern-like arms. The arms start at the base with five rays then begin to divide from there. The arms are flexible due to the multiple calcium filled joints, also called ossicle; therefore if needed these arms could coil up and provide...

Noble feather star Comaster nobilis
2013-05-18 06:36:19

The noble feather star (also known as the yellow feather star) reaches up to 15.75 inches in diameter with a cup-shaped body. There can be 35-40 arms extending out of the central part of the body. The arms are primarily yellow with the underside having a variation to include black, green, or white. The noble feather star feeds on food debris, phytoplankton and zooplankton. Phytoplankton and...

Mediterranean feather star Antedon mediterranea
2013-05-18 06:26:42

The Mediterranean feather star is a filter feeder that obtains food by straining suspended matter and food particles from water. The star has a stalk that has up to forty tendrils, (threadlike organs) which help the star cling to hard surfaces. The “body” of the star is called a calyx and is shaped like a small cup. This calyx is surrounded by feathery pinnules bearing arms. These arms are...
