musickatia [10]

Answer:

C.  Oceans are carbon sinks because they store more carbon than they emit.

Explanation:

Oceans are carbon sinks because they store more carbon than they emit. Most of the carbon is produced in the respiration process as well as burning of fossil fuels. This carbon moves to the atmosphere and dissolved into the ocean which is required by the vegetation of ocean. Due to this carbon, vegetation produced more food for the organisms. About 25% of all CO2 emissions are absorbed by the ocean. Source is the part of a plant where materials are produced e.g. leaves whereas Sink refers to the part of the plant where the substrate can be stored e.g. roots or stem for starch.

Caffeine prolongs and intensifies the effects of epinephrine. Which of the following potential mechanisms of action of caffeine
kherson [118]

Answer:

a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.

Explanation:

The phosphodiesterases are a group of enzymes that are capable of breaking phosphodiester bonds such as those between nucleotides in nucleic acids. The Cyclic adenosine monophosphate (cAMP) is a second messenger involved in intracellular signaling pathways. This molecule (cAMP) is hydrolyzed by the cAMP-dependent phosphodiesterase, which catalyzes the enzymatic breakdown of phosphodiester bonds (i.e., hydrolyzing cAMP to 5-AMP). The cAMP levels are modulated by the balance between its generation and the degradation via cyclic nucleotide phosphodiesterase.

What does it mean when dna is openly floating around the cytosol
vaieri [72.5K]

Most, maybe all, bacteria have their genome DNA tethered to their cell membranes, so it is in the cytoplasm but its not really floating around. Plasmids in bacteria however are free floating. This is why it's so easy to isolate plasmids from bacteria with centrifugation after lysing.
