One example of a positive feedback loop in childbirth is contractions. When the contractions start, they produce oxytocin, which stimulates stronger contractions, which produce more oxytocin.
I think this one <span>best describes computer modeling in biology: </span>a. A computer is used to calculate a scale of a lake’s turbidity due to algal growth from too much nitrate pollution in the water.
At the Joes injury, the grey matter looks like a butterfly-shaped are. While the white matter has tracts which are either ascending or descending. For example, we have corticospinal which is ascending tract. Grey matter it is the thin cerebral cortex for each hemisphere of the cerebrum and it is composed of interneurons which integrate information.
White matter consists of myelinated axons that lie low below the cerebral cortex.
The two hemisphere connects together by the corpus callosum.
Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.
