Rods and cones are similar in that they both release glutamate as the primary neurotransmitter. During signalling the rod and cone photoreceptors signal their absorption of photons via a decrease in the release of the neurotransmitter glutamate to bipolar cells at its axon terminal. Every rod and cone photoreceptor release the same neurotransmitter, glutamate.
The hydrogen bonding that created its hexagonal shape....the molecules get closer together and there will be more hydrogen bonding making it solid
Answer:
Explanation:
DNA polymerase is an enzyme that helps in the synthesis of new strands of DNA. It is found in both prokaryote and eukaryotes. In prokaryotes, there are 3 types of DNA polymerase and more DNA polymerase found in eukaryotes.
The 3 types of DNA polymerase are DNA polymerase I, DNA polymerase II, DNA polymerase III. The DNA pol I and DNA pol II helps in DNA repair rather than DNA replication. The DNA pol III is the major enzyme that initiates the replication.
DNA polymerase III is a multisubunit enzyme that functions as a dimer of these multiple subunits. The DNA polymerase enzyme has 3 significant enzymatic activities -
All DNA polymerase direct the synthesis of DNA from 3' to 5' end.
It possesses 3' to 5' exonuclease activity. It also helps in proofreading activity by replacing the incorrect nucleotides with the correct base sequence.
Some DNA polymerase has a 5' to 3' exonuclease activity. It is found in the lagging strand.
DNA polymerase is not able to initiate DNA synthesis alone. They need a free 3' end, where the enzyme can add new nucleotides. It means they require 2 primers to initiate the DNA replication in both the direction.
The strands act as complementary to the DNA polymerase. The DNA polymerase adds new strands continuously in 5' to 3' direction in the leading strand. While in lagging strand short fragments of DNA formed. Later they attached by DNA ligase.
DNA polymerase also needs RNA polymerase in some cases to start replication. Such a process is called reverse transcription.
I believe it is D. More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory.
Answer:
D. Dynamic equilibrium
Explanation:
Equilibrium is when the amount of solution outside the cell is equal to the amount inside. A dynamic equilibrium is when this homeostasis is kept through a continuing process. Therefore, since homeostasis is constantly being maintained the solution will be equal on both sides of the cell.
