Prophase This answer can be found in the book on page 232‚ “Prophase – centrosomes move away from each other‚ propelled partly by the lengthening microtubules between them.” 4.) If cells in the process of dividing are subjected to colchicine‚ a drug that interferes with the formation of the mitotic spindle apparatus‚ at which stage will

On the first day of class‚ we had a wonderful guest speaker who came from Japan to speak with us on different aspects pertaining to Indians living in Japan. Yuka Mizutani discussed how many Indians lived in Japan‚ but the Japanese government only wants the world to see them as only having Japanese people. As a result of this‚ the Indians had to blend in with the normal Japanese people and they were not allowed to have their own cultural identity. They were forced to speak and write Japanese to make

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.
