How will you present your data (charts, graphs, types)? To determine if the type of agar affects bacterial growth, a scientist cultures E. coli on four different types of agar. Five petri dishes are set up to collect results: One with nutrient agar and E. coli One with mannitol-salt agar and E. coli One with […]

Determine the variables tested in the each of the following experiments. If applicable, determine and identify any positive or negative controls. 1. A study is being done to test the affects of habitat space on the size of fish populations. Different sized aquariums are set up with six goldfish in each one. Over a period

What are the independent and dependent variables? Independent Variable: Dissolved oxygen concentration. Dependent Variable: The number of fish. 5. What would be your control? Possible Control: Aquarium with no fish. Measure the dissolved oxygen level in a fish tank at normal room conditions, and repeat this measurement every time you make an observation of

What would your experimental approach be to test this hypothesis? Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. Possible Hypotheses: 1. The amount of dissolved oxygen affects the number of fish that can live in a body

What patterns do you observe based on the information in Table 4? No fish are present when the dissolved oxygen is zero. When there is more dissolved oxygen in the water, more fish are present. However, the number of fish tends to drop or level off when the dissolved oxygen is higher than 12 ppm.

Mendelian Genetics Lab Background The laws of segregation, independent assortment, and dominance, discovered in the mid 19th century by Gregor Mendel, form the basis of all genetics. The ability to predict the results of crossing experiments and explain any variance between expected and observed results is still a vital part of our understanding of heredity.
