APPLICATION QUESTIONS

What can be said about the affinity of Ligand B for its receptor in comparison to Ligand A? Which has the higher Kd?

Open system organisms have a restriction for size because of the system they use. However, gastrovascular cavity organisms do not have a size limitation, why?

These organisms are so thin and only rely on diffusion to move nutrients and oxygen throughout the body.

Compare and contrast the three types of systems. Make sure to include: Where you would relatively find this organism (water/land), Size limitations (if any), any adaptations they can do, and an example organism.

OPEN SYSTEM / CLOSED SYSTEM / GASTROVASCULAR SYSTEM
These organisms are larger and need nutrients delivered directly to the tissues because diffusion is too inefficient. They live in a variety of habitats and can modify or adapt the circulatory system to fit their needs

EXPLAIN WHAT HAPPENED IN THE RABBIT EXPERIMENT AND WHAT THE MAIN OUTCOME/RESULTS WERE? WHY IS THIS IMPORTANT?

Testosterone is produced by Leydig cells in the testis, promotes secondary sexual characteristics in males, production is promoted by luteinizing hormone, and stimulates the activity of sertoli cells

The XX and XY animals had female secondary sex characteristics because he removed the gonads of the rabbits.
