As a cell increases in volume, the relative surface area decreases and the demand for resources increases. This is not a good combination, as cells will not be able to get resources as efficiently. The surface area to volume ratio decreases, diffusion or the movement of materials in and out of the cell, happens at a slower rate. Formulas: Surface Area of a Cube = 6s2 Volume of a Rectangular Solid = lwh Surface Area to Volume Ratio = SA/V If you had a cell that was cube-shaped with a side length of 20µm, calculate the surface to volume ratio of the cell. Round your answer to the tenths place.

Ijust need with an idea of how to write it or example.1. for this assignment you will create a developmental timeline. the timeline should include significant events, or possible future significant events, from your entire life—from womb to tomb. you are encouraged to personalize your timeline with pictures, etc. for each incident or event that you list, you need to relate it to a concept developed by piaget, kohlberg, or erikson. for example, if one of your events is, “i said my first word, ball,” and you have this on your timeline at 15 months, you also need to say, “piaget’s preoperational stage.” along with each event you discuss, provide a brief description of its significance. score
