You have been asked to make a presentation to the International Environmental Conference 2009.

Describe the three key points that you would make in your presentation.

consider the structure of the neurotransmitters: Acetylcholine, Noradrenaline, Adrenalin, dopamine, glycine, serotonin, y-aminobutyric acid and glutamic acid and suggest what type of binding interactions could be involved in binding them to a receptor binding site, and identify possible amino acids in the binding site which could take place in these binding interactions

What orders of insects are primarily wingless? Of these, which orders are primitively wingless (never evolved wings) and which have evolved winglessness from winged ancestors? What are the advantages and disadvantages of being wingless?

Hi, I in Human Genetics.discussing questions on the single gene trait dwarfism and how ir relates to dominand and recessive gene alleles.

My question is:

When discussing how dominant gene alleles and recessive gene alleles determine expression of single-gene traits, such as dwarfism, what are the current prognostic, diagnostic and treatment capabilities for dwarfism? Thank you!
