How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution O sections of DNA are more similar in organism more closely related,
bones (homologous structures) are used for similar uses if the organisms are more closely related
organisms that are more closely related are found with similar embryonic structures.

d. making up measurements to record.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.

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!
