A Reflectional Symmetry is a type of symmetry in which one half of the object is the mirror image of the other. 1  A figure may have both horizontal and vertical lines of reflection. 2  The alphabet V has reflectional symmetry about a vertical line of reflection.  The hexagon has reflectional symmetry about both horizontal and vertical lines of reflection.
RENAL REGULATION OF BICARBONATE. The kidneys regulate the [HC03-] by. 1) conserving or excreting the HC0 3 - present in the glomerular ultrafiltrate; 2) producing new HCO3- which enters the body fluids as the kidneys excrete ammonium salts and titratable acids (this sum is called net acid) in the urine.
They form in much the same way that stratovolcanoes do. Where are Cinder Cones Located? Cinder cones occur either at subduction zones or on the flanks of other volcanoes. It is possible for a small volcanoes to pop up on the side of, say, a stratovolcano to release the pressure inside. How Do Cinder Cones Erupt? Cinder cones erupt fairly violently, though they are not as dangerous as stratovolcanoes.
