Osmoregulation as a Homeostatic Mechanism using the Comparitive Melting-Point Method for two Crab Species. Abstract Two crab species‚ Plagusia and Cyclograpsus‚ were collected from a local estuary in the littoral and deep water zone for osmoregulation studies. To examine differences in osmoregulatory mechanisms among the species‚ haemolymph of the specimens was extracted once they were acclimated to varying concentrations of seawater. Using the comparative melting-point‚ capillary tubes were

Provide examples to support your thinking. -The lack of homeostasis (called homeostatic imbalance) can cause several different types of diseases and disorders. Homeostasis will make sure of the efficiency in control functions of the body. Diabetes‚ gout‚ and any disease caused by a toxin in the bloodstream result from homeostatic imbalance. 2.

The spinal cord is about 17 inches long and has three protective layers like the brain: the outer dura mater‚ the

The Structure & function of the Autonomic Nervous System Introduction: The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart‚ stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls
