The underlying process that drives movement of materials across membranes is

In the space below, answer ONE of the following questions: For each of the following pairs, tell me which one  best describes a catabolic reaction:               Builds large molecules  /  Breaks down large molecules               Water is brought into the molecule(s)  /  Water is removed from the molecule(s)                Energy is stored in bonds  /  Energy is released from bonds OR For each of the following genotypes, list the gametes that the individual would produce (put commas between gametes).                      Tt:                XHY:                Bbrr:  

Imagine that in guppies, blue (B) is dominant to red (b), and long fin (L) is dominant to short fin (l).  Given the following cross: BbLl     X     Bbll What are the phenotypes of each of the parents? Excluding any duplicate gametes from a single parent, how big would the resulting Punnett Square be?  Give your answer as  # X # of squares.

In a molecule of RNA, the nitrogen-base A always pairs with [letter1], and G always pairs with [letter2].

In the space below, answer ONE of the following questions: Define passive transport and active transport, including any differences between them.  Water balance actually occurs at the cellular level, and maintaining the proper water balance is very important to an organism.    We see the results of this water movement in our daily lives.  Explain why your lettuce gets wilty when you pour vinegar-and-oil dressing on it (make sure to use the proper terminology).  Include the following in your answer:  water and solute concentrations, concentration gradients, type of solution, direction and mechanism of movement, and result to cells. OR Describe how a strand of DNA can eventually become a protein through the processes of transcription and translation.  Include the location of each of these processes, the main events of each, and the names and roles of each of the three types of RNA.
