A student rescan, her decides to perform an experiment on the effect of the thyroid gland on frog metamorphosis. She sets up three aquaria with tadpoles. She adds thyroxine to the water of one, the drug thiouracil to a second, and nothing to the third. Thiouracil destroys thyroxine. Assuming that the student uses appropriate concentrations, predict what will happen.

A student rescan, her decides to perform an experiment on the effect of the thyroid gland on frog metamorphosis. She sets up three aquaria with tadpoles. She adds thyroxine to the water of one, the drug thiouracil to a second, and nothing to the third. Thiouracil destroys thyroxine. Assuming that the student uses appropriate concentrations, predict what will happen.

Expert Solution & Answer

Summary Introduction

To predict:

The things that might happen to three sets of tadpoles when the first set is grown in presence of thyroxine, the second set is grown in presence of thiouracil, and third is grown in normal water.

Introduction:

In the given scenario, a researcher wants to conduct an experiment on the effect of the thyroid gland in metamorphosis in the frog. For her experiment, she sets up three aquaria. In the first aquarium, she added thyroxine. In the second aquarium she added thiouracil and in the third nothing was added.

Explanation of Solution

The metamorphosis can be defined as the process through which the newborn animal physically develops into an adult by undergoing several changes. It is the feature of all the chordates and is induced by iodothyronine.

Thyroxine induces metamorphosis in the frog. In the aquarium in which thyroxine was added; the tadpoles will metamorphose into frog earlier than the normal tadpoles. Thiouracil destroys the thyroxine, thereby inhibiting the metamorphosis. So the tadpoles growing in the aquarium containing thiouracil will not show metamorphosis.

The thyroid gland of tadpoles produces a normal amount of thyroxine, which is sufficient to induce metamorphosis. So the tadpoles growing in the aquarium containing normal water will metamorphose at a normal rate.

Conclusion

The tadpoles growing in normal water will undergo metamorphosis at a normal rate, the tadpoles grown in presence of thyroxine will have metamorphosis earlier than normal. The tadpoles grown in presence of thiouracil will not undergo metamorphosis as it would be inhibited by thiouracil.

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.)
