Metamorphic grade refers to the temperature and pressure under which a rock was metamorphosed, considered low grade or high grade. Since metamorphic minerals in a rock form under specific conditions, they are used to identify the temperature and pressure of the metamorphic conditions.rotolith or parent rock is the rock type that a metamorphic rock was before it was subjected to metamorphic conditions.
Filtration occurs at the glomerulus, essential a highly coiled loop of tubular cells. Each kidney has millions of these cells. Arterial blood is pumped into the glomerulus. Water and ions are filtered via an osmotic gradient as well as other waste products.
does glomerular filtration occur in the renal corpuscle, then the tubular reabsorption occur in the proximal convoluted tubule and nephron loop and then the tubular secretion occur in the distal convoluted tubule??ubular secretions: It is the mechanism by which substances are removed from the blood and are directly added to the tubular fluids. Hydrogen ion, ammonium and drugs such as penicillin are some of the substances that move from the blood into the distal tubule of nephron.
