Controlling microorganisms in the environment is becoming increasingly difficult due to the development of resistance to common disinfectants and antiseptics. Some examples of chemicals that have been or which are currently being used are triclosan, triclocarban, benzalkonium chloride, and chloroxylenol, to name a few. Many scientists are now turning their attention to other methods to control bacterial contamination. Discuss using 'phages' and other methods to control bacteria. Do you think these methods are better? Safer?

Researchers want to estimate the size of two populations of Galapagos tortoises on two different islands. They do this by making two trips to each island. On the first trip to Island A, 50 tortoises are captured and marked, and on the second trip, 60 tortoises are captured, of which 8 are marked.On the first trip to Island B, 47 tortoises are captured and marked, and on the second trip, 38 are captured, of which 13 are marked. Estimate the population sizes of Galapagos tortoises for these two islands. Round to the nearest whole number (2 pts.).

After 5 years, there are an estimated 386 individuals on Island A, and 139 individuals on Island B. Assuming geometric growth, which island has a higher growth rate? And what will the population size of each island be in another 5 years? Give your answers to 3 decimal places (5 pts.).

1. Oxidation of 1g carbohydrate, fat and protein yields 0.56, 1.07, and 0.42 g metabolic water respectively. Retention of 1g of dietary protein yields 0.16 g metabolic water whereas 0.07g of water is prduced when 1 g of dietary fat and carbohydrate, respectively, are retained as fat.

For a lactating cow consuming 15 kg DM/day and feed contains 76% carbohydrate, 4% fat, and 14% crude protein;

How much metabolic water will the cow produce under the following scenarios:

(i) If 65% of carbohydrate, 70% fat, and 60% crude protein is oxidized?

(ii) If 15% of crude protein, 15% fat, and 12% carbohydrate is retained?

The reason why trypanosomes like Trypanosoma brucei are successful invading into the bloodstream is due to antigenic variation of a homogeneous Variant Surface Glycoprotein (VSG) coat. However, to accomplish this, the trypanosome VSG gene in the active expression site is degraded and replaced with the donor VSG gene. Explain why there is not an eventual loss of these VSG genes in the trypanosome genome over time.
