The Kepler spacecraft was designed to investigate humanity’s last unexplored frontier: the far reaches of space. The NASA space telescope looks deep into the Milky Way galaxy for signs of habitable planets where humans could potentially thrive. In the thousands of planets, it has identified, three are in livable orbits similar to Earth. The planet most similar to Earth is Kepler 186f, known as “Earth’s cousin.” Over 490 light years away, all that NASA knows is that Kepler 186f’s size...

Inborn errors of metabolism Trisomy 21 (Down syndrome) Chromosome number Klinefelter syndrome (XXY syndrome) Aneuploidy Microevolution can occur as the result of all of the following processes except ______. natural selection random mating mutation genetic drift migration Although natural selection works to decrease the frequency of deleterious alleles in a population's gene pool, deleterious recessive alleles often remain in the gene pool. What maintains deleterious...

A decrease in plasma volume will decrease plasma hydrostsatic pressure. This can be detected by the cardiovascular baroreceptors which send a signal to the cardiovascular control center which sends nervous impulses to the arterioles to constrict. Constriction decreases flow to the capillary beds, in turn decreasing flow out of the capillaries at the capillary beds served by this arteriole. This prevents further decrease in plasma volume. Is this an osmotic mechanism? Is this a homeostatic mechanism? Is it negative feedback?...
