Biology Review and Study Guide Cell Division and Cancer Cells divide for two main reasons: first‚ the larger a cell becomes‚ the more demands the cell has on its DNA. Second‚ a large cell has more trouble moving enough food in and enough waste out. Before it becomes too large‚ a growing cell divides. The two new cells are referred to as daughter cells. The process by which a cell divides into two cells is called cell division. Mitosis is part of the eukaryotic cell cycle during which the

55. a) Cuticles on the outermost layer of angiosperms are clear‚ which allows for light to pass through. The leaf is shaped in a way that will allow it to absorb more sunlight and be more efficient. Photosynthesis takes place in the spongy parenchyma and the palisade parenchyma. In order to obtain food‚ it is controlled by the stoma which controls the passage of gas and water. b) Water and food is transported through the xylem. The water will eventually be transported to the leaf tissue while the

Biology Coursework ¡V Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. Variables The input variable which will be used in this investigation will be the light intensity (this will be a 100Watt bulb being moved closer and further away from

Percentage of all cases of TB in Benin that are cured is -40 positive negative 2%. c. Two reasons why countries should aim to be in the target zone: • High detection rate combined with high cure rate slows down spread of TB • High detection rate combined with

If the statement is false‚ change the underlined word or words to make the statement true. True 9. All heterotrophs must eat food to get energy. True 10. Autotrophs do not need to eat food because they make food. False sunlight 11. The energy in food originally came from ATP. False pulling together 12. The term photosynthesis means “pulling apart with light” in Greek. True__ 13. The energy of sunlight is stored in the chemical bonds of carbohydrates. 14. Complete the table
