A Raisin in the Sun is written by Lorraine Hansberry. The author wrote this because when she was younger she experienced this. In this play‚ there are struggles that are going on. For example‚ discrimination and segregation. The family is currently living in a small apartment and are not rich but the characters Mama and Walter try to make everyone happy. The setting is in Southside Chicago. The two characters that have influenced the plot so far are Mama and Walter because they have been involved

surroundings‚ it tries to make concentration of solution inside and outside itself equal. However‚ the solutes are too big to pass the cell membranes without the help of channel proteins‚ or transport proteins. Water may freely pass through the membrane by osmosis‚ which requires no energy. Thus‚ the cell starts to take in‚ or release‚ water until it is isotionic to its

of different concentrations of saline solution on Red Blood Cells. When a Red Blood Cell is submersed in a high concentration of saline solution it will create a hypertonic environment and therefore cause the cell to rupture due to the process of osmosis. The methods used to collect data were observation and note taking. Overall the results proved the hypothesis correct with major findings being a higher concentration of salt causing a hypotonic environment and a low concentration. Recommendations

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

A Raisin in the sun talks about the racial and social struggle 1950s and 1960s. The racial segregation is the main topic companying the human conflict centered on the family Younger in Chicago. One could argue that the play was written as a silent‚ cultural protest against the racial segregation when it comes to rights for living spaces. The play started with family Younger´s life in a small apartment with the following main characters: Walter Younger‚ his wife Ruth‚ his son Travis‚ his sister Beneatha

that are selectively permeable. In other words‚ they allow certain things in and certain substances are not allowed to enter the inside of the cell. Osmosis is the process of water movement across the membranes from an area of high water concentration to an area of low water concentration to reach a sense of equilibrium. Diffusion is what enables osmosis to occur.

I believe someone who has a change in anyway‚ whether it’s in heart o anything else‚ for good has grown and become dynamic. Dynamic is characterized as a constant change in activity or progress. Perhaps the most dynamic character in Hansberry’s A Raisin in the Sun is Beneatha because of her change in identity‚ career‚ and love. The first reason why I believe she is the most dynamic character is because of her change in identity. During the beginning of the play Beneatha had straight hair‚ along

The Effect of Concentration Gradient on Osmosis Abstract: Osmosis is the passive movement of water from an area of higher concentration to an area of lower concentration‚ usually across a membrane (Thorpe 2013). Tonicity is the ability of a solution surrounding a cell to gain or lose water (Reece 2011). There are many factors that affect the rate of osmosis. These include temperature‚ surface area‚ difference in water potential‚ pressure‚ light and dark and most importantly what we will be talking
