Summary Introduction

To write:

Expert Solution & Answer

Explanation of Solution

The brain, which is a part of the central nervous system of a vertebrate, has changed a lot during evolution while the spinal cord has evolved very little. The weight of the brain is similar to that of the spinal cord in most of the vertebrates, while in humans, it is 55 times more than that of the spinal cord.

In humans, the brain of an adult male weighs about 1,600 g while in females it weighs about 1,450 g. The difference is due to the difference in body size between the two sexes and is not related to intelligence.

Conclusion

The typical weight of an adult brain in human males is about 1,600 g, and in an adult female, it is about 1,450 g.

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.
