Metabolism of a human body inevitably produces a variety of unwanted or waste products. This waste product is not simply needed by the body. If it is allowed to accumulate in the body, it may produce harmful effects. These wastes are completely excreted from our body through digestive tracts, respiratory tracts, and by the sweat glands. The principal system that is involved in the excretion of waste is the urinary system. From the blood, the metabolic waste is removed by the kidney. The rest of the urinary system involves in the elimination of urine, storage, and for transport. The kidney plays an important role in controlling the blood pressure and blood volume. Kidney physiology is administrated by certain principles. This includes osmotic pressure, down pressure, and electrochemical gradients. The stages of urine production and the role of the kidney (regulating urine concentration and fluid balance) mainly depend on concepts like osmolarity, tonicity, and osmosis.

From your previous experiment, you found that this enhancer activates stripe 2 of eve expression. When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?

What experiment could you do to see if the maternal gene, bicoid, is sufficient to form anterior fates?

You’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene. Describe an experimental technique you would use to find out where this particular eve enhancer is active.
