Never work together again d. Study something else

  3. Warm Up 8-24-16 • Bacteria and archaea are two types of prokaryotes. Which of the following characteristics describes only archaea? a. They lack a nucleus c. They are unicellular b. They have cell walls d. found in extreme environments • What are the three main types of archaea? a. Heat lovers, methane makers, and salt lovers b. Prokaryotes, eukaryotes, and bacteria c. Cyanobacteria, bacteria, and eukaryotes d. Producers, consumers, and decomposers

  4. Warm Up 8-23-16 • The ability to respond to environmental stimuli is observed in a. Rocks c. Plants b. Rain drops d. Sugar crystals • Which statement correctly describes ALL living things a. They reproduce sexually b. Their cells have a nucleus c. They are made of at least one cell d. They can change energy from the Sun into food. • Kelly wanted to find out how many different types of bacteria were on the doorknobs at school. To find this out she could a. Design an experiment c. Ask her teacher b. Take a guess d. Use an encyclopedia

  5. Warm Up 8-22-16 Identify the: • Control Group • Independent Variable • Dependent Variable • What should the boss’ conclusion be? • How could this experiment be improved? A boss thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, the boss counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.

  6. WARM UP 8-19-16 • WHAT IS THE DIFFERENCE BETWEEN PROKARYOTIC AND EUKARYOTIC CELLS? 2. WHAT IS THE DIFFERENCE BETWEEN AUTOTROPHS AND HETEROTROPHS? 3. WHAT IS THE DIFFERENCE BETWEEN ASEXUAL SEXUAL REPRODUCTION?
