Biology - Final Review (50 Questions) Scientific Method Observations: New observations are made and past data are studied Hypothesis: A testable statement is formulated Experiment/Observations: The hypothesis is tested by experiment of further observations Conclusion: The results are analyzed. • If the hypothesis is support. Continue work (multiple experiences) • If the hypothesis is rejected. Start again (new hypothesis) Car Scenario: Observations: Vehicle won’t start Hypothesis:

Emily East November 22‚ 2014 AP Biology: 4th Hour Mitosis & Meiosis Test Corrections 3.) At which phase are centrioles beginning to move apart in animal cells? E. 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

Bonnie Bell Mrs. Legary Biology P.6 21‚ Sept. 2011 Milk Lab Final This investigation consists of testing the reaction between milk‚ food coloring‚ and dishwashing soap. Different kinds of milk were tested‚ depending on the amount of milk fat content. The investigation was based on 2 questions. Lab one’s problem statement‚ using only milk fat and food coloring was: How does food coloring react in different kinds of milk fat? The second lab’s problem statement‚ using milk fat‚ food

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate

Preliminary Biology Assessment task 2013 A Local Ecosystem Mangrove Swamp Cassandra Mandelik Introduction: A mangrove is a tree‚ shrub‚ palm or ground fern‚ generally exceeding the height of one and a half metres. They normally grow above mean (average) sea level in intertidal zones of marine coastal environments as well as estuarine margins. A mangrove also refers to the tidal habitat comprising of such trees and shrubs. Australian mangrove systems are highly effecting by human presence

Biology Vocabulary: 1. Immigration: influx of individuals into an area 2. Emigration: movement of individuals out an area. 3. Logistic growth: (shown with an S-shaped curve) population growth that levels off at carrying capacity. 4. Exponential growth: (shown as J-shaped curve) geometric increase of a population as it grows into an ideal unlimited environment. 5. Niche: the sum total of a species use of the abiotic and biotic resources in its environment 6. Symbiosis: an ecological relationship
