Toward a New Vision: Race‚ Class‚ and Gender as Categories of Analysis By: Patricia Hill Collins Summary- The author writes about oppression in society and how it is full of contradictions. She states that there are no pure victims or oppressors‚ but rather everyone experiences a different amount of penalty and privilege based on their race and social status. She believes that if women and people of colour could find that they have common grounds in regards to class‚ it will eliminate racism

1. Plant breeders wanted to produce a better variety of tomato by selective breeding. Two plants‚ of the varieties Tangella and Piranto‚ were crossed. (a) Some flowers of each variety were covered with cellophane bags. The diagram shows a covered flower and a brush. (i) Explain why some flowers were covered with cellophane bags during the selective breeding. .......................................................................................................................... ........

Simple diffusion The term simple diffusion refers to a process whereby a substance passes through a membrane without the aid of an intermediary such as a integral membrane protein. The force that drives the substance from one side of the membrane to the other is the force of diffusion. In order for substances to pass through a cell membrane by simple diffusion it must penetrate the hydrophobic core of the phospholipid bilayer. The types of molecules that can do this are themselves substantially

Discussion: 1. Peter was preparing some potatoes for cooking. He put some water in a pot and added some salt. He cut up the potatoes and put them in the salt solution. Then the telephone rang and he spent 30 minutes talking to George. When he returned to put the potatoes on the stove they were flaccid (soft). Explain what happened to the potatoes. The concentration of free-moving water molecules is higher in potato cells‚ the cytoplasm of the cell is hypertonic. The water molecule will flow from

Introduction In this investigation‚ me and my partners performed an experiment to find the different energy contents in food and different amounts of energy released when consumed. Throughout this experiment our procedure was to take different food samples and use a device known as a calorimeter made from a can of aluminum‚ one large paper clips and a string of copper wire to measure the amount of thermal energy released during a reaction. By measuring the temperature difference before and after

In 1882‚ Belgian cytologist Pierre-Joseph van Beneden discovered that the gametes of the roundworm Ascaris contained two chromosomes while somatic cells contained four. B. Fertilization 1. van Beneden proposed in 1887 that an egg and sperm could fuse to form a zygote. 2. The fusion of gametes is called fertilization or syngamy. C. Meiosis 1.
