BIOLOGY 2020 LAB LAB 4 – Sensory Systems I. Vision 1. Know the types of photoreceptors in the retina. (Remember there are 3 different types of cones) 3 cones i. Blue- short ii. Green- Medium iii. Yellow-Red- Long 2. Why would near point accommodation change as you get older? (Think about what happens to the lens and the muscles of the eye with age) As you get older‚ the lens becomes hardened. The elasticity of the lens decreases dramatically with age‚ resulting in difficulty

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.) Male and female sex

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements
