BIS 2A What is the difference between channel proteins and carrier proteins? - CORRECT ANSWER-While they are both transport protiens active in facilitated diffusion, channel protiens are always open and work faster than carriers. While carrier protiens bind to a substance and change shape for that substance to pass through. What is Tonicity? - CORRECT ANSWER-The ability of an extra cellular solution to change in volume by affecting osmosis. What is osmoregulation? - CORRECT ANSWER-Mec...

BIS 2A Midterm 1 Britt Which of the following statements best describes covalent bonds? - CORRECT ANSWER-the sharing of an electron pair between atoms; relatively strong bond Which of the carbon atoms is most oxidized? - CORRECT ANSWER-CO2 How can living things grow and display increasing levels of order, reorganizing random molecules into complex organized molecules? - CORRECT ANSWER-living things capture the energy from their environment, like nearby exergonic reactions, and use tha...

Hydrogen bonds e. a, b, and d -CORRECT ANSWER- e. a, b, and d In animals, if the fuel consumed exceeds energy expended, fats are synthesized from carbohydrates in order to store the excess energy. Acetyl-coA Carboxylase catalyzes the first dedicated step in fatty acid synthesis. This enzyme responds to a larg...

Pre-lab: Introduction to Lab 8 In this, the *nal lab of the quarter, you will be asked to solve a series of small puzzles in metazoan evolution. In BIS 2A you learned about mechanisms of genetic change, and in BIS 2B you learned how natural selection operates on individuals to produce genetic change in populations. You realize now that agents of natural selection can be biotic factors, such as interactions with predators and prey, as well as abiotic factors, such as temperature or moisture...
