Expert Solution & Answer

Explanation of Solution

Bipedalism has many advantages and disadvantages. One such advantage is that it makes an individual efficient in carrying food and run long distances. Eventually, freed hands enable the organism to create and use tools. However, this feature would require a large brain which happened millions of years ago after bipedalism.

Disadvantages of bipedalism are: bipeds are easily located by predators; they have a risk of back injuries, including slipped discs, and arthritis. As walking upright lifting heavy objects and carrying heavy items put a substantial strain on the lower back, sometimes the strain is so high that legs break down and blood pools, causing the veins to bulge. Thus, the individual becomes unable to move.

Conclusion

In this way, an individual can identify the negative and positive of a trait.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
