What is the main difference between aerobic and anaerobic respiration?

the diffrence between the 2 are

aerobic respiration : requires oxogen, occurs in the mitochondria of cells, produces a lots of ATP per glucose molecule, and used when heart rate and breathing rate rise

anaerobic respiration : occurs in the cytoplasm of cells, dosen't require oxogen, used during the first 1 -2 minutes of exersise , and produces less ATP per glucose molecule

i hope this helps and i hope you had a great day

the answer is kevlar

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
