Brainlies ! effects of seasonal changes on these 4 aquatic organisms : turtles- snakes- water lily- mangrove leaves-

Really, Geny? Really?

I am almost done... look...

This is copied from our google doc:

Turtles get affected by seasonal changes because the climate is warm, more and more eggs will become female, which will then lead to less genetic diversity in sea turtle populations.

Snakes, such as the garter snake, use the changes in temperature between seasons to time their reproduction and hibernation. These snakes slither into the underground dens they have built to wait for the cold temperatures to stop. Once it gets warm again, garter snakes are done with hibernation. They come out from their little homes to court and reproduce.

Water Lily - As the summer heat rolls in, the shade that ends up being provided by the water lilies became increasingly important for keeping fish and other aquatic animals cool. The shade also causes the growth of algae to be limited, which might otherwise bloom more than it needs to, which would then lead to decreased oxygen levels in the water. It would also cause many fish to die, as well as other species.

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!
