The town where sanjay and his family live wants to cut back on their use of non-renewable resources at home. the town is located in the area we call the great plains, in the state of kansas. the town's people want to cut their dependency on non-renewable resources. they also want to minimize the amount of particulate matter they put into the atmosphere. given the town's location, what would be good energy resource choice or choices for them to consider?
a) natural gas
b) wind and solar
c) hydroelectric power
d) biofuels and biomass waste

Option B, wind and solar

Explanation:

Kansas has high potential for production of wind energy. It is one of the state of America which can meet nearly 75% of its energy requirement by harnessing wind energy to its full potential.

As per the estimate of 2012, Kansas has produced nearly 960 giga watts of wind power. However it has a capacity of producing 3200 TW of electricity from wind resource only

Along with wind energy, if solar energy can be harnessed upto its full extent then nearly 42% of the total energy requirement can be met .

Hence, option B is correct

cell regulation is conducted by special proteins.

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!
