Fishes and their characteristics that distinguish them from other animals. Introduction: Around 550 million years ago (mya), that is in the early Paleozoic era, the fishes have appeared first. The fishes approximately comprise around half of 64,000 vertebrate species. Among the living groups of fishes, the five main groups include cartilaginous, lobe-finned, ray-finned fishes, lampreys, and hagfishes.

Expert Solution & Answer

Explanation of Solution

The fishes are defined as the aquatic vertebrates having gills as well as appendages in the form of fins. They mainly differ from other animals in their bodies, which is streamlined that allows the fishes to move through the water. They move at angles or forward using the fins. They are capable of maintaining the composition of body fluids in seawater as well as freshwater environments as they have excellent organs for the exchange of water and salt. They have excellent visual as well as olfactory senses. The gills of fishes are very effective in oxygen extraction; even a very low amount of oxygen is present. They also have a lateral-line system and this provides sensitivity to vibrations and water currents.

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.
