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?

In tomato,a plant with smooth,red fruits was crossed with another plant having wrinkled green fruits.The F1 generation yielded plants all of which produced smooth red fruits.What are the phenotypes of F2 and in what proportion?using punnet diagram show how you arrived at your answer.
What is missing in our understanding of plant or animal genetics, to create a new organism artificially? I understand the phases of development, but don’t understand why we cannot take the chemicals of a seedling or embryo and create them artificially? What is still missing? And if we could create artificial life, wouldn’t it solve many of the problems of infertility and botanical flourishing?
