A. Gauge the size of various biological components and organisms. The Virtual Microscope can be used to make these observations. Estimate the size (length and width in microns) of
• 1. An E. Coli cell
• 2. A mitochondrion.
• 3. A Red blood cell
• 4. A virus.
• 5. A water molecule
B. Observe the various Cell types and learn to distinguish between Bacterial cells, Plant cells (1, 2), and Animal cells (1, 2, 3)
• 1. Observe and describe three differences between prokaryotic and eukaryotic cells.
• 2. Observe and describe three differences and three similarities between plant and animal cells.

Write My Essay For MeC. Form a hypothesis
• 1. Hypothesize about how you might be able to sort a mixed population of cells into prokaryotes and
eukaryotes. Try to be practical, build on your understanding of the differences between the two cell classes.
• 2. Hypothesize about a means to separate out plant cells from a mixed population of eukaryotic cells.

bacterial growth
A. Bacterial Growth. Observing the growth of the bacteria Streptococcus pneumoniae
These Streptococcus bacteria have been placed on a nutrient rich agar medium and their growth visualized. You can monitor their growth by watching the middle frame and moving through time with the time step buttons.
• Estimate how long it takes for this population of bacteria to double. Hint- this population doubles multiple times during the duration of this recording.
B. Cellular Reproduction : The Cell Cycle (1 , 2 , 3), Mitosis (1 , 2), Meiosis (1 , 2), and Binary fission (1 , 2).
• 1. Estimate the percentage of time that a constantly developing cell spends in interphase.
• 2. In a random selection of 100 such cells, estimate the number that would be undergoing mitosis at any given time.
• 3. Understand the basic differences between mitosis, meiosis, and binary fission. Is mitosis
more similar to meiosis or to binary fission? Explain your reasoning.
C. Cellular Metabolism: Cellular Respiration (1 , 2), Photosynthesis (1 , 2), and The Carbon Cycle (1 , 2 , 3)
• 1. In a paragraph or two compare and contrast photosynthesis and cellular respiration.
• 2. Describe the ecological relationship between photosynthesis and cellular respiration.
• 3. Hypothesize about what might happen if a large number of producers were suddenly removed from the biosphere. Where might carbon accumulate if the ratio of number of producers to consumers was markedly reduced?

A. Phenotype and genotype of Dragons For fun, you can use this web lab to answer these questions: What genotype(s) result in wings? What genotype(s) result about a brown skinned Dragon? If necessary use your own research to answer the following questions.
• Define genotype and phenotype.
• What is an allele?
B. Drosophila Lab Enter the lab as a guest. You need to purchase a breeding pair of flies. Purchase a female mutant that has a small (vestigial) wing size and a male wild type fly. Breed them and notice the resulting distribution of phenotypes.
• Describe and explain the characteristic of the first generation (F1) of flies. Is the vestigial wing characteristic dominant or recessive?
• What percentage of the F1 generation would show the recessive characteristic phenotypically according to your table? Are your experimental breeding results consistent with what you expect from this assumption and the logic of the Punnet square?
• Breed two of these F1 flies. To do this select a male and a female from the results of your first cross and put them in the breeding jar. Describe and explain the characteristics of the second generation (F2) flies.
C. Genetic Disorders Library Describe the three main classes of genetic disorders and give an example of each.
