18 gru 2016 · This section of the AP Biology curriculum focuses on cell size and shape. More specifically, it looks at how the surface-area-to-volume ratio of a cell helps determine how efficient that cell is at exchanging macromolecules with the external environment.
This question focuses on the differences between two types of science: basic science and applied science. Basic science or “pure” science seeks to expand knowledge regardless of the short-term application of that knowledge.
A sarcomere is defined as the distance between two consecutive Z discs or Z lines; when a muscle contracts, the distance between the Z discs is reduced. The H zone—the central region of the A zone—contains only thick filaments and is shortened during contraction.
