14. Read the following portion of the Isle of Arca Archa and answer the question that follows​.

​Arca Archa has 6 ports where products come onto the island and waste leaves the
island. The ports are heavily guarded so that no materials enter or leave the island
without permission. Near the center of Arca Archa the largest building on the island sits
on top of a hill. People call the building The Hall of Justice, and all decisions to run the
island are made in this structure.
Just down the road from this large building is The Big Muscle Brick Factory. The factory
makes bricks that are used to build structures all throughout the island. At the northwest
corner of Arca Archa, a power plant sits in view of the ocean. The power plant burns
natural gas to make electricity, which is used all over the island. Next to the power plant
is the Use It Again Recycling Center. In this center waste products from around the
island are broken down so that they can be used again by the island’s inhabitants or
more easily transported off the island.

* Compare the island to a cell. Which part of a cell does the description most closely
resemble? (SB1a)

A. Ports –
B. The Hall of Justice –
C. The Big Muscle Brick Factory –
D. Power Plant –
E. Use It Again Recycling Center –

the answer is d (apex) good luck : ))

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

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!

the answer is c on e2020, bud.
