Question

A student sets up a controlled experiment to test the effect of a fertilizer on plant growth. They use 2 tomato plants, one is given 1 cup of water every day, 1 cup of fertilizer every week, and daily sun exposure with a constant temperature. The second plant is given 1/2 cup of water every day, no fertilizer, sun exposure every other day, and a constant temperature. Using your knowledge of the Scientific method, why is this not a good experimental design? 1. The second plant should also be given some fertilizer. 2. The second plant had different controls, so it cannot be compared for just the effect of fertilizer. 3. The second plant should have a change in temperature. 4. The second plant should not have that much water every day. Diabetics can now obtain insulin that has been manufactured by what biological advancement? 1. HGP 2. hybridization 3. gene splicing 4. cloning The Krebs cycle and electron transport take place in which part of the cell? 1. cytoplasm 2. mitochondria 3. nucleus 4. vacuoles
