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

The Mammalian Urogenital Lab Questions 1. The urine needs to be stored in egg-laying animals so that the fetus is not trapped in pools of urine inside of the egg. This keeps the urine separate from the fetus and its nutrients. 2.

Discussion: In this experiment a ketone‚ 9-fluorenone is reduced to and alcohol. The are two possible ways by which this reduction can occur. One is by a catalytic hydrogenation‚ this uses a catalyst such as palladium or nickel‚ hydrogen gas‚ and heat/pressure. This can reduced an alkane to alkene. This catalytic process is preferred in industrial practices because the cost is low in the long run and more importantly there is little to no waste expense. However‚ hydrogen gas is dangerous due to
