A scientist hypothesizes that if the inner membrane of a mitochondrion were smooth instead of folded, less ATP would be produced. Why would this affect ATP production? A. there would be less fluid available in the mitochondrion
B. there would be more space available in the mitochondrion
C. there would be less surface area on the inner membrane
D. there would be no means of transporting materials through the inner membrane

i am at class 5 sorry brother

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.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
