rerio are used for developmental research. (4 marks) Organisms | Advantages | Disadvantages | A. thaliana used for plant development research | 1.) Tiny Genome- Therefore it is easy to study the genes and also to manipulate the genes.2.) Short Life Cycle- Experiments conducted on the A.thaliana will have observable results fast as the development of the plant is rapid.3.) Small size-can be cultivated in a tiny space and this is vital because research areas usually have space limitations.4.)

Write a simple equation to show how ATP is synthesised from ADP: ADP + Pi ATP Give two ways in which the properties of ATP make it a suitable source of energy in biological processes: 1. Energy released in small/suitable amounts 2. Soluble 3. Involves a single/simple reaction Humans synthesise more than their body mass of ATP each day.

Lab 12: Meiosis kimberleigh Lewis Biology 1408-63400 Consider the Concepts Experiment: 1. A common misconception about meiosis appears when students identify which of the two divisions converts a diploid cell into two haploid cells. Meiosis I is the division immediately following DNA replication and replication does not occur again before meiosis II. However‚ meiosis I is the "reduction" division when a diploid cell forms two haploid cells. If the DNA duplicated before meiosis I‚ how

series of eight steps‚ each catalyzed by a specific enzyme. One enzyme used is succinate dehydrogenase which catalyzes the conversion of succinate to fumarate‚ thus loses hydrogen ions and electrons for use in generating ATP. It is important to know what inhibitors affect the activity of this enzyme which eventually will affect the whole process of cellular respiration. In this experiment‚ 1M Malonate( CH2(COO)22-) and 0.1M of Sodium Fluoride (NaF) ‚were employed as inhibitors to the enzyme
