Biology
1.Why might a biologist be interested in comparing the amino acid sequence of proteins between two different species? What differences might she find when comparing species that are distantly related or closely related? Explain.
2.Trans-fatty acids are a type of unsaturated fat. Most trans-fats consumed today are industrially created as a side effect of partial hydrogenation of plant oils (Crisco). In trans-fat molecules, the hydrogens on the doubly bonded carbon atoms (characteristic of all unsaturated fats) are straighter, rather than kinked, in shape. This straightening produces an unnatural molecule. Why do you think trans-fats are considered unhealthy as compared to other unsaturated fats? Can you explain your answer chemically?
3.Most adult humans lose the ability to digest dairy products, a condition known as lactose-intolerance because of an inactivity of the lactase enzyme for digestion. However, there is a high degree of lactose
