To begin their work, they set up a yeast culture in Elle's kitchen using sugar as a food source. Their initial data is shown in the graph below, and gives the mass of yeast per cc or milliliter of culture. What is not true about this data? A. The carrying capacity has a value of 6.7 mg/cc. B. The growth rate at 24 hours cannot be determined. C. The yeast stopped growing due to limited food. D. The data shows a density-dependent factor. 7.5 6.아 4.5 3.아 1.5- 0 2 4 6 8 10 12 14 16 18 20 Hours Amount of yeast (mg/cc)5 In plants, what is the name given to the male gamete joining the female gamete? A. Pollination B. Fertilisation C. Insemination D. Implantation 6 Which of the following explains the relationship between proto-oncogenes and cancer? Proto-oncogenes code for the production of CDK and cyclin proteins, which regulate the cell cycle. 7 A. B. Proto-oncogenes pause the cell cycle to allow for DNA repair. C. A mutation in a proto-oncogene can lead to excessive CDK and cyclin production, which result in uncontrolled cell growth. D. A mutation in a proto-oncogene can lead to excessive CDK and cyclin production, which prevents uncontrolled cell growth. The Agapanthus plant is often used for creating microscope slides of guard cells. Students strip the epithelium from the leaf to create a slide.

D.…5. Very happy Escherichia coli cells reproduce on a 20 minute time frame (doubling or generation time).

Using the information in problem 3, make another plot showing how DX and DP (rates of production of cells and product) vary with D (on the same graph), covering the same range of dilution rates in problem 3. 5. Genetics & Gene Control A. Explain the difference between a DNA strand, a chromosome and a gene. B. Would a cell with a deletion or a point mutation be more likely to revert back to the original phenotype? Why? C. Define feedback repression. On a basic level, how does this work in a cell?2. By what process does the carbon dioxide in the phenol red move into the plant exposed to light? 3. During which photosynthetic process does the plant in the light use the CO₂ that it removed from the phenol red solution? F. LOCATION OF STORED SUGARS (STARCH) IN VARIEGATED LEAVES Variegated leaves are leaves whose pigments are not evenly distributed in all cells. The cells of portions of the leaf which appear clear or white have no photosynthetic pigments. Those cells in the colored portions of the leaf contain chlorophyll and one or more of the accessory pigments. These pigmented cells are the site of photosyn- thesis in variegated leaves. a. Recall that some of the sugars produced in photosynthesis are stored as starch. Using the technique of leaf clearing and selective staining, you will determine whether starch is stored in the pigmented or non-pigmented portions of a variegated leaf. Procedure Your instructor will clear a leaf by boiling it in ethanol to remove the pigments.…
