Tetraalkylammonium compounds

Tetraalkylammonium compounds block non-specific cation channels by sticking into the pore. What would the effect of these toxins be on vertebrate vision? Why? Thank you.

Intracellular and Extracellular Fluids

I explain in clear layman's terms the effects of the following on intracellular and extracellular fluids: 1. eating a salty meal 2. hemorrhage 3. intravenous isotonic saline solution.

Biological Radioactivity Test - Theoretical

Remember the nuclear accident at Chernobyl (former Soviet Union - now the territory of Ukraine) in 1986? A scientist suspects that the food in a nearby ecosystem may have been contaminated with radioactive nitrogen over a period of months. Which substances in plants and animals could be examined for radioactivity to test


Using the negative feedback system, explain how osmoreceptors and CO2 receptors maintain water balance and respiratory rates. Include a diagram. How are micturation and defecation reflexes different? NOTE: Moved from Physiology to Biology to expose question to different Online TAs.

This job compares cerebral cortexes.

I understand that a mammal brain with a relatively smooth cerebral cortex would have a smaller surface area compared to a mammal brain with many sulci. This job examines the effect on the habits of these mammals in respect of feeding, breeding etc.

Body Metabolism

Sports scientists distinguish between aerobic fitness (as achieved, for example, by long distance running) and anaerobic fitness (as achieved by sprinting exercise). ----------------------------------------------------------------------------------------------- Why have they chosen these particular terms to describe these two

The body Metabolism

Involving the glycolysis, what is the net gain of ATP? What does "net" mean? For each turn of the Kreb's cycle, how much ATP is produced? How many molecules of CO2 are produced? What is the significance of stripping off high-energy electrons from the pyruvate?

The Digestion System
