Bellwork 1. What is the independent variable in the experiment? 2. What were some of the variables she controlled 3. Which material was the best at moving heat into the water (best conductor) 4. A Blue flower BB is crossed with a white flower bb. What are the possible

genotypes and phenotypes. 5. Amoebas reproduce asexually, what kind of cell division do they use? 6. How are traits passed from one generation to the next? Florida Benchmark SC.7.L.16.4 Recognize and explore the impact of biotechnology (cloning, genetic engineering,

artificial selection) on the individual, society and the environment. What is biotechnology? Biotechnology is the use and application of science to living things. For thousands of years, humans have been using biotechnology to breed plants and animals, and to ferment foods using bacteria and yeast.

What are some types of biotechnology? Some of the techniques of biotechnology include artificial selection, genetic engineering, and cloning. Artificial Selection the process of selecting and breeding organisms that have certain

desired traits Doesnt change DNA causes certain alleles to become more common in a population Ex corn, dogs http://www.pbs.org/wgbh/harvest/engineer/select.html Genetic engineering

http://www.livebinders.com/play/play/225759 the process in which a piece of DNA is modified for use in research, medicine, agriculture, or industry. Scientists change DNA in an organism, or take DNA from one organism and transfer it to another.

http://www.livebinders.com/play/play/225759 cloning Making an exact copy of another organism or cell Form of asexual reproduction http://learn.genetics.utah.edu/content/tech/cloning/clickandclone/

How does biotechnology impact our world? Examples of applications of biotechnology: changing the DNA of mosquitoes so they cannot spread malaria cloning an endangered species of animal such as the gaur modifying corn and soybean DNA to make them

resistant to plant-eating insects How does biotechnology impact our world? Biotechnology can impact both our society and our environment. We must weigh risks and rewards when using biotechnology.

Artificial Selection, Genetic Engineering, or cloning? 1. Scientists introduce a gene to the DNA of fish that causes them to glow 2. Scientist gathers DNA from clothing at a crime scene. He makes copies of the DNA to study it 3. Wild Carrots have thin white roots. Over time, farmers have selected carrots with thick orange roots

4. Diabetes is treated with insulin. The gene for producing insulin has been inserted into the DNA of bacteria to produce human insulin Glowing Mosquito DNA from a jellyfish has been introduced to mosquito larva. The mosquito begins to glow. They want to use this same idea to change its DNA so it cant spread Malaria.

1.How might this effect Individuals and Society? 2.How might this effect the environment? Tough Plants Much of the corn grown in the US is genetically engineered. The plants have bacterial genes that make them more resistant to plant eating insects. 1. Effects on individuals and society?

2. Effects on Environment? Bellwork A scientist has produced a gentically engineered apple that resists disease. - what happened to the DNA in these trees? - Give examples of potential benefits to society - Give examples of potential risks to society
