Which question most closely relates to the
forester's observations and the collected
scientific data on forests?
are deer eating most of the young
hemlocks?
did a lack of rain cause the
hemlocks to stop reproducing?
why are there so many deer in the
forest?
do the young hemlocks have a
disease?

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

hi i’m going crazy about going tomorrow and i’ll tell you what i’m doing and i wanna is a way ya

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!
