Why evolution is considered one of the core themes of biology. Concept introduction: Evolution is defined as the changes in heritable characteristics of all organisms in a population from one generation to the next. It depends upon the natural selection, mutation, and genetic drift. It is mainly the “ changes in gene frequency in a population ”.

Expert Solution & Answer

Explanation of Solution

Evolution explains the most basic things related to life. It gives a logical explanation that all the living organisms have been derived from a single ancestral species. Organisms that are better fitted with their environment for survival are selected by the process of natural selection, and mutation creates new alleles. In genetic drift, random variation in the allele frequency occurs due to the large changes in a population within a short duration of time. Evolution provides the evidence for the distribution of DNA, shows the anatomical similarities and differences, different body symmetry, and geographical distribution of organisms within a different environment. Hence, it is considered to be one of the core themes of biology.

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.
