Anatomy of a Kidney
There is a very brief video with still images of the kidney. This is a quote from the video:
"This cross section of a kidney, almost three times life-size, shows its blood supply and one of the filter tubules, a nephron, highly magnified. The nephron is a highly specialized coiled tubule measuring up to one inch in length. There are more than one million nephrons in each kidney. They function as the kidney's filter units. The kidneys filter unwanted materials from the blood and regulate th

Parallelogram and Trapezoid Comparison
This video makes comparisons of the characteristics of trapezoids and parallelograms. Addressing the question as to whether a parallelogram is also a trapezoid. The answer will depend on your definition of trapezoid. If a trapezoid has exactly one pair of parallel lines, then parallelogram doesn't fit within those conditions or parameters. If your definition of trapezoid states that is has at least one pair of parallel sides, then all parallelograms could be considered trapezoids. Your answer th

Caves - Extreme Conditions for Life
For certain life forms on Earth, conditions that humans and other familiar organisms find hospitable can actually be deadly. Instead of a moderate climate with an atmosphere rich in nitrogen and oxygen, these organisms thrive in very hot or very cold temperatures, or in caves or deep waters where no light penetrates. In this video segment adapted from NOVA, scientists analyze communities of cave-dwelling microbes that live off simple inorganic compounds like iron and sulfur. Based on their findi
