Calvin Williams Chapter 20 1. Advances in recombinant DNA technology allow scientists to work with smaller fragments of DNA‚ give them more tools to dissect and analyze DNA‚ and also allow for them to make many copies of a strand of DNA. 2. Restriction enzymes are made by bacteria to cut up invading DNA. They target specific base sequences in the DNA and then work to cut out those sequences from the DNA. 3. When a restriction enzyme cuts out a portion of DNA‚ it will sometimes leave a sticky

Courtney S. 4th Period SINKERS and FLOATERS Purpose:The purpose of this investigation is to provide an overview of photosynthesis and to design and conduct an experiment to test the factors that affect the rate of photosynthesis. Hypothesis:If 10 leaf discs are placed into 2 plungers and placed under a lamp the CO2 rate will speed up the process of photosynthesis. Materials: -Fluorescent lamp - Hole punch - 1 Sharpie marker -20 leaf discs -Syringes -12 mL cups Data Table Start 2 4 6 8

it was not until my first test in AP Biology‚ that I realized I actually had to go the extra mile and put forth maximum effort into studying and reviewing. I needed a biology mentor like Mrs.Ciasulli to bring out the best in me because she knew of my aspirations to work in the medical field. Although she attempted to make my life as difficult as possible‚ she made me fall in love with the material and gain much more appreciation for the study of biology. AP Biology then became the class I was most

Biology Unit 2 Module 2 1.1: Explain the uptake of ions by active transport in roots; * Emphasize the role of the endodermis. Most plants secure the water and minerals they need from their roots. The path taken is: soil -> roots -> stems -> leaves The minerals (e.g.‚ K+‚ Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth. Most of it is

Government Involvement Regarding “Green Policy” Energy‚ natural resources‚ conservation—these are all hot topics in Washington today. But‚ to what extent should the United States government be responsible? America is in desperate need of a “green revolution” (Friedman).
