Science is subdivided into specific areas of study termed disciplines. These divisions are artificial but are helpful to narrow the massive scope of scientific knowledge to a manageable amount. Given what you know about each, which scientific division is likely to present the best answer to a question about how fluid dynamics affect blood pressure in mammals?
A. Bioinformatics – use of technology to study and store biological data B. Biochemistry – study of chemical reactions needed for life function, usually at the cellular level. C. Biology – study of life D. Biophysics – study of biological processes through physics

An experiment mixed together oil (lipids), organophosphate-containing detergent in water, and copper ions to act as a catalyst for a chemical reaction. Membranes budded off of the oil in this mixture. Which of the following is a reasonable and possible explanation of the experimental results?
a. The chemical reaction caused the organophosphates from the detergent to chemically combine with lipids from the oil to form phospholipids. The hydrophilic tails lined up towards each other with their hydrophobic heads pointing out towards the water; this configuration formed a phospholipid bilayer that pulled into a liposome. b. The chemical reaction caused the organophosphates from the detergent to chemically combine with lipids from the oil to form phospholipids with hydrophilic heads and hydrophobic tails. The hydrophobic tails lined up towards each other with their hydrophilic heads pointing out towards the water; this configuration formed a phospholipid bilayer that pulled into a spherical liposome. c. The copper ions permanently, chemically combined with the lipids to form phospholipids. The hydrophilic tails lined up towards each other with their hydrophobic heads pointing out towards the water; this configuration formed a phospholipid bilayer that pulled into a liposome. d. The copper ions permanently, chemically combined with the lipids and phosphates to form phospholipids. The hydrophilic tails lined up towards each other with their hydrophobic heads pointing out towards the water; this configuration formed a phospholipid bilayer that pulled into a liposome.
