PLEASE HELP!! You are raising hogs for market, and your veterinarian recommends that you switch the type of feed given to the mature hogs. The vet is concerned that the present feed is too high in protein. While a high protein diet is recommended for young, growing hogs, food too high in protein can cause kidney problems in the adult animals. You switch feed and notice that the weights of your mature animals drop. You want healthy animals with maximum weight, but you do not know how to solve the problem. You design an experiment that would help you solve this problem. You think that the higher protein ration is the best way to maintain your weight gain. You have 40 hogs and you divide them into two groups. To one group, you feed the high protein feed, to the other, you feed the lower protein ration. All 40 hogs were farrowed within 10 days of each other. They are all about the same weight when you begin this experiment. Each group of 20 hogs is in the same size pen in the same barn. You weigh all hogs before the experiment, place them on feed for 3 weeks and weigh the hogs again.

explanation:

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

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!
