Which of these is NOT an Agile Principle?

Software engineers do not need to concern themselves with ethical issues, only technical issues.

Which of the following is best used to present complex conditions and actions in an easy-to-read format?

During cellular respiration from one molecule of glucose, a total of 10 NADH and 2 FADH₂ are produced before oxidative phosphorylation begins. If only ATP produced from oxidative phosphorylation is counted (ignore substrate-level ATP), how many ATP are generated?

When phospholipids are placed in water, they automatically arrange themselves into a bilayer. Why does this occur?

A scientist studies a protein found attached to the inside surface of an animal cell’s plasma membrane. The protein contains mostly polar and charged amino acids and does not have any long stretches of hydrophobic amino acids. When mild chemical treatments disrupt weak bonds, the protein easily detaches from the membrane without damaging the lipid bilayer. Based on membrane structure principles, which statement BEST describes this protein?

An animal cell is placed in a hypotonic solution. What will most likely happen to the cell?

A researcher isolates a transmembrane ion channel from cardiac muscle cells and analyzes its amino acid sequence. She discovers that a long stretch of approximately 22 consecutive amino acids within the middle of the protein is composed primarily of nonpolar residues such as leucine, isoleucine, valine, and phenylalanine. When this region is experimentally replaced with charged amino acids, the protein no longer embeds within the plasma membrane and instead remains in the cytosol. Based on principles of membrane structure and protein chemistry, which explanation BEST accounts for this observation?

A researcher is studying oxygen diffusion across the thin respiratory epithelium of a frog’s lung. She experimentally reduces the surface area of the lung while keeping the diffusion distance, temperature, molecular weight of oxygen, and concentration gradient constant. According to Fick’s law of diffusion, what would be the expected physiological consequence, and why?

Glucose enters skeletal muscle cells down its concentration gradient via a transport protein without ATP use. This is:
