This paper is about how the plant cells and solar cells are similar to each other as well as how they are different to one another. In addition this paper explains how the laws of thermodynamics apply to each of the plant and solar cells system. Plant Cells and Solar Cells Photosynthesis is the process of producing and releasing oxygen in the air. It needs sunlight‚ carbon dioxide and

Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

Living Alone or Living with Roommates Nowadays‚ a lot of attention has been drawn to the issue of whether college students should live alone outside the campus or live together with other roommates in the students’ dormitory. Opinions are divided on this issue. Those who are in favor of living with roommates have their own advantages. With several students sharing the same room‚ they could learn how to tolerate the difference between individuals. However‚ others argue that students who live outside

partially supported because glucose left the bag and is proven by the positive test on the surrounding water. Also the beaker turned orange because of osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable

other hand‚ they will learn how to use money wisely by living alone. Since these young adults who live alone do not have any financial support by their parents‚ they have to learn how to use money wisely or how to earn money to make sure they can live. For example‚ the young adults who live alone have to calculate carefully about every expense. Although living with parents can reduce the financial stress and save money for young adults， living alone can make them become a wise user of money. Easy

The Cell membrane surrounds all living cells and is the most important organelle‚ there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The membrane controls how and what substances can move in and out of the cell/organelle The structure of the membrane is often referred to as the “Fluid Mosaic Model”; this is because of the way it is structured It is composed of phospholipids‚ proteins‚ and carbohydrates‚ which are arranged in a fluid
