The oxygen–hemoglobin dissociation curve describes the percent oxygen saturation of hemoglobin as a function of the partial pressure of oxygen (po2) in the surrounding fluid. as the po2 increases on the horizontal axis, the oxygen saturation percentage also increases on the vertical axis. in comparison to that of adult hemoglobin, how is the fetal oxygen–hemoglobin dissociation curve shifted?

typically, most spiders possess eight eyes. however, others have as many as 12, and some don't have any. these eyes are for detecting light from dark, deciphering shapes and for gathering their prey.

glycolysis is a process that fuel your metabolism. it is apart of cellular respiration the process that produce atp.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
