Observation Gathering information, either through direct use of the senses or with the help of tools such as microscopes, thermometers, and balances that extend our senses. Can reveal valuable information about the natural world Hypothesis Tentative answer to a well-framed question -- an explanation on trial. A rational account for a set of observations, based on the available data and guided by inductive reasoning. 00:12 01:41 Hypothesis-Based Approach Systematic tria...

What is its electron configuration - -shells 1, 2 and 3 are full and shell 4 has one electron -Which type of bond represents a weak chemical bond - -hydrogen bond -Which of the following statements is not true - -Water is the most abundant molecule in the Earth...

BCHE 5180 / 6180 FINAL EXAM | Graded A.Based on what you have learned about the functioning of enzymes and proteins, explain why the pH in the cell has to be buffered. A large group of enzymes show a pH optimum for their activity. This value is normally close to the pH in the cell. When the pH in the cell changes this can lead to a protonation or deprotonation of an amino acid that is important for the enzymatic activity. As a result the activity will decrease. Upon large changes in pH add...
