A. Discuss the limitations upon cell size imparted by unfavorable changes in the surface area to volume (SA/V) ratioas cells have become larger in evolutionary time.
B. There are two structural adaptations of eukaryotic cells that enable them toattain larger sizes than prokaryotic cells. One of them is compartmentalization. You will be asked to discuss that in Part Cof this question. What is the other structural adaptation and how does it contribute to the resolution of the SA/V problem?
C. How does the presence of a compartmentalized cytoplasm reduce the burden of transport in large cells with unfavorable SA/V ratios?
The correct folding of proteins is necessary to maintain healthy cells and tissues. Unfolded proteins are responsible for such neurodegenerative disorders as Alzheimer's, Huntington's, and Creutzfeld-Jacob disease.

Suppose that a cell's demand for ATP suddenly exceeds its supply of ATP from cellular respiration. Which statement correctly describes how this increased demand would lead to an increased rate of ATP production?
Two phenotypes are found for the cuteness trait, cute (C) which is dominant to extreme cute (c). You have a cute Stevious whose mother was extreme cute. Determine the number of copies of the cute allele present in each stage of meiosis.
A circular coil enclosing an area of 160 cm2 is made of 210 turns of copper wire. The wire making up the coil has resistance of 7.0 ?, and the ends of the wire are connected to form a closed circuit.
