 With regards to entropy, how does water contribute to the hydrophobic effect?

 With regards to entropy, how does water contribute to the hydrophobic effect? 37. Where would you find hydrophobic amino acids on globular protein? Transmembrane protein? Why? 38. What is required for molecular surfaces/interfaces to interact with one another for a sufficient amount of time (such as an antibody/antigen)? 39. Why are weak bonds important to macromolecular […]

Which one of the following statements is true when comparing starch and cellulose?

Which one of the following statements is true when comparing starch and cellulose? Starch is made of amino acids and cellulose is made of glucose monomers. Starch is made from a different enantiomeric form of glucose than cellulose. Starch is a disaccharide whereas cellulose is a polysaccharide. Animals make starch whereas plants make cellulose.

Hypothesis about finding fossils

Hypothesis about finding fossils. Describe a line of evidence that, if true, would disprove (or provide evidence against) evolution. Fossil Rabbit in the pre-Cambrian! (JBS Haldane, explaining what evidence would indicate evolution, date unknown. ) DO NOT rephrase Haldane’s above hypothesis about finding fossils in the wrong time.

Sample solution containing lipids

Sample solution containing lipids. Started my lab but don’t understand what would be the proper way for the conclusion as many of my hypotheses were wrong. As well how to properly answer the questions Part 2: Testing for Lipids Background Information: Lipids are a class of molecules that are not soluble (do not dissolve) in […]

What types of gene or protein families may be important for multicellularity?

What types of gene or protein families may be important for multicellularity?  Can we compare the genomes of different multicellular lineages like animals and plants to identify the most important genes critical for multicellularity?  Why or why not?   10) As we have discussed in the lecture, homeotic genes specify the segmental identity and all […]
