What would you expect to occur if you treated Gonium concurrently with both colchicine and cycloheximide? Explain your answer being sure to describe the exact mechanisms of inhibition and timing.
What is HDL
Given that a solution containing a 0.2 M concentration of a weak acid and 0.5 M of the negatively charged ion has a pH value of 4.4, find the pK value of the weak acid. Express the result to two decimal places.

The metabolic rate R ( kJ day-1) of mammals varies with their body
mass M (kg) according to the power law R=k M3/4. where k is a constant.
A common shrew has a mass of 9 g and a metabolic rate of 7 kJ day-1.
(a) What is the metabolic rate in kJ day-1 of a dog whose mass is 5 kg? Give the answer to at least 3 significant figures.
(b) What is the mass in kg of a cat with a metabolic rate 560 kJ day-1? Give the answer to at least 3 significant figures.
The dense, round structures in the micrograph above are cells of one hazardous phytoplankton species present in 250ml of water sample.
(a) How many of these cells are present in this sample?
(b) What is the number of cells of this phytoplankton per litre of water?
(c) For this phytoplankton, 100 cells/Litre is a “trigger” value for indicating whether the water is hazardous. Does this sample exceed this “trigger” value?
