Sodas get their fizz from the CO2 gas dissolved in them. Based on the solubility curve of carbon dioxide, which statement would be most accurate about soda?
A.
Cold soda will taste less bubbly, because the solubility of carbon dioxide in water is lower at lower temperatures.

B.
Cold soda will taste more bubbly, because the solubility of carbon dioxide in water is higher at higher temperatures.

C.
Warm soda will taste more bubbly, because the solubility of carbon dioxide in water is higher at higher temperatures.

D.
Warm soda will taste less bubbly, because the solubility of carbon dioxide is lower at higher temperatures.

In familial hypercholesterolemia individuals homozygous for the allele causing the disorder completely lack receptors on liver cells that take up cholesterol from the blood stream. heterozygous have one-half the number of receptors while individuals homozygous for the normal allele are phenotypically normal. this is an example of a. epistasis b. complete dominance c. incomplete dominance d. codominance

Why do some dna fragments move farther than others during gel electrophoresis? a. because their shapes are different b. because they are different types of molecules c. because the samples are different colors d. because their masses are different

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
