• An investigation was done to see if keeping the lights on for different amounts of time each day affects the number of eggs chickens laid

• Independent variable• Dependent variable• Controlled variables• Control Experiment

• An investigation was done to see if keeping the lights on for different amounts of time each day affects the number of eggs chickens laid

• Independent variable- amount of light• Dependent variable- # of eggs• Controlled variables- same age chickens, same

space to live, same food• Control Experiment- chickens with normal

night and day light

This kingdom involves organisms that can’t make their own food, they have no cell wall, and they are mostly multicellular.

This Kingdom contains single celled organisms with no nucleus that can commonly cause diseases.

This Kingdom involves multicellular organisms that can not make their own food but have cell walls made of chitin.

This kingdom contains organisms that are single celled but have a nucleus. These can be either heterotrophic or autotrophic.

•Compare and Contrast DNA and RNA

DNA and RNA both have the bases Adenine, Guanine and Cytosine. They are both made up of sugar groups, phosphates and bases. However, DNA is double stranded and can not leave the nucleus. RNA is single stranded and can leave the nucleus. RNA has the sugar group Ribose and DNA has the sugar group Deoxyribose.
