DNA supercoiling means under or over winding of the DNA strand and basically is to become more condensed and more organized. Supercoiling is very important as it compacts the genetic code and as if that was not enough supercoiling also regulates and oversees the access the the genetic code.
Answer:
"GFP contained in synaptic vesicles moved into the synaptic cleft by exocytosis."
Explanation:
Synaptic vesicles are small membrane sacs that carry neurotransmitters from the cell body where they are produced, to the presynaptic membrane of the terminal button where they are released. The release zone of the presynaptic membrane contains voltage-dependent calcium channels. When an action potential depolarizes the presynaptic plasma membrane,
-channels open, and
flows into the nerve terminal to trigger the exocytosis of synaptic vesicles, thereby releasing their neurotransmitters into the synaptic cleft
Answer:
B
Explanation:
in photosynthesis CO2 is used to produce glucose NOT energy.
in cellular respiration O2 is used to produce energy NOT CO2.
in cellular respiration oxygen is used to produce energy and CO2.
Answer:
Eukaryota, Archaea, Bacteria
Explanation:
They are the largest taxonomic groups.
Answer;
(c) It can bond with other carbon atoms that are bonded to other molecules
Explaation;
-Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.
-Carbon chains can bond with carbon rings to form very large, complex molecules. These large molecules can be made of many small molecules that are bonded together.
