Scientists developed genetically obese rats in the laboratory. These rats had a low level of the protein called adipsin. Researchers have proposed that adipsin directly affects hunger.
High levels of adipsin decrease hunger, while low levels of adipsin increase
hunger,
How might this research affect humans?
O by improving cloning techniques
by decreasing appetites through medication
O by slowing the aging process through medication
by improving digestion and increasing metabolism

depends on if you on plato or not

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
