Factors Influencing Rate Photosynthesis Occurs ...

Approximately 2.2 billion years ago Earth's atmosphere experienced a rapid accumulation of Oxygen. Photosynthesis played an intricate role in the evolution of the Earth's early atmosphere. Describe in detail one of the factors influencing the rate at which photosynthesis occurs, and explain how it effects the rate.

Overcoming Limits Placed on Body by Cellular Respiration

We live in an age which has seen great scandal involving athletes and performance enhancing substances. Describe one method by which an athlete may enhance his or her performance and overcome the limits placed on the body by cellular respiration.

Chemicals involved in transduction of the stimulus to nerve impulses

In discovering a new chemosensory organ in the crayfish swimmeret, describe the experiments that can be performed to identify the chemicals involved in the transduction of the stimulus to nerve impulses (G-proteins, cAMP, IP3 etc.). Please offer any feedback - if you feel that I haven't explained the question well enough, o ...continues

Examples of possible hypothethical grant proposal experiements

This is not real, but mearly a non-fiction scenario: In isolating a novel protein from th esynapse of a cocroach that I have discovered, I get to name it too. Using immunohistochemistry, I determine that the chemical is found in axon terminals. Thus, I suspect that it might have something t do with synaptic release of vessicle ...continues

I am looking for help getting started on this and am hoping that you ca ...continues

Interpretation of intracellularly recording from pyramidal cells in a mouse

I am recording intracellularly from the neocortex of a mouse. If I place my electrode on one set of pyramidal neurons (Layer 2) and add fenfluramine (a serotonin uptake blocker), whithin 5 minutes the neurons produce GREATER amount of action potentials. But when I place fenfluramine while recording from another set of pyramida ...continues
