Dr. Paul discovers a new chemical that he predicts will increase energy levels in hamsters. He designs an experiment to test his prediction
Dr. Paul separates 12 hamsters into two equal groups. He gives one group of hamsters the chemical but does not give the
chemical to the other group. He keeps everything else about the hamsters' living environment the same.
Over the next month, Dr. Paul measures the time that the hamsters spend running on their exercise wheels each day. He then
calculates averages for these measurements, which are shown in the table below.

i think the answer is g1

hope i

explanation:

okay now i don't know this but for the pints nothing else to say bye

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

i think its white blood cells

i hope this
