Plant physiologists have found that solutions of ABA with concentrations as low as 5.0 μmol dm-3 will cause stomata to close. How will you prepare a range of solutions of ABA from a stock solution of 1.0 mmol dm-3 and use the solutions to find the lowest concentration that stimulates stomatal closure in leaves of Arabidopsis thaliana?

ADH, insulin and glucagon are hormones that control aspects of homeostasis. ADH is a short peptide, glucagon is a single polypeptide and insulin is composed of two polypeptides. The target cells for these hormones only respond if they have specific cell surface receptors.

Explain why the target cells for ADH, insulin and glucagon must have cell surface receptors in order for them to respond.
