Lab 3: Mitosis and Meiosis Purpose: The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Hypothesis: I predict that

Biology textbook- pg. 80 3) Distinguish between the autotrophic and heterotrophic nature of plants and animals. Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there

Terra shiles English 232 Mullinax September 18‚ 2013 The Book vs. The Movie The Legend of Sleepy Hollow written by Ivring was a very interesting story that is well known around the world today. The movie was far more entertaining than reading the book If I must say so myself. Tim Burton gave a new spin to The Legend of Sleepy Hollow. I myself have always enjoyed anything written or directed by Tim Burton because of his sense of horror and his creative abilities. The characters are redefined

Drew Staples 6/12/14 Properties of water Question Does mixing water with other substances change it’s boiling point. Research The boiling point of a liquid is when the temperature causes the vapor pressure to be equal to the air. Air density will change waters boiling point. High altitudes give water a lower boiling point. Hypothesis If the water is less dense then it will boil faster and the boiling point will be lower.

Aim: To investigate the effect of skin sensitivity in response to cold temperature in different parts of the body by timing the maximum amount of time in which ice-pack can be held to that area. Hypothesis: If the layer of skin is relatively thin‚ the nerve response to cold will be the fastest‚ increasing the skin’s sensitivity. This therefore means that the fastest responses to cold will be in the face‚ and specifically the nose. The skin consists of 3 main layers; the epidermis‚ dermis and

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks

Evolution Unit: Objectives AP Biology Upon the completion of the textbook readings in Chapters 22-26 you should be able to: Chapter 22 1. Explain how the principle of gradualism and Charles Lyell’s theory of uniformitarianism influenced Darwin’s ideas about evolution. The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection

respiration and photosynthesis cycle is the process by which plants and animals interact in a codependent and symbiotic manner to produce the nutrients‚ gases‚ and energy that they require to survive. Plants obtain energy from sunlight and use it to combine carbon dioxide and water into glucose and oxygen. This process is called photosynthesis. Animals eat plants containing glucose‚ and combine glucose and oxygen‚ releasing energy‚ water‚ and carbon dioxide. This process is called respiration. Plants take in
