Lunar maria (plural form of the Latin word mare, which means sea) are
dark surfaces that can be found all over the moon (17% of the Moon is
covered in them) that have been created as a result of volcanic
eruptions. These areas are made up of basalt, and given that they seemed
almost waterlike, the astronomers in the distant past mistook them for
seas, whence their name comes.
When it comes to craters, their origin
is quite similar - volcanic eruptions created them. When lava starts
erupting from a volcano, it has to get out from somewhere - and thus
craters are created. If you are referring to lunar craters, however,
there are many speculations as to how they were created: due to volcanic
eruptions, meteoric impact, or glacier activity.
Alcohol fermentation occurs in the cytosol of yeast cells.
Answer:
b. Chemiosmosis
Explanation:
Chemiosmosis refers to the process during which phosphorylation of ADP into ATP is driven by the energy of an electrochemical gradient. This electrochemical gradient was generated during the transfer of electrons down an electron transport chain. The components of the electron transport chain pump the protons across the membrane to produce a proton concentration gradient. During chemiosmosis, protons diffuse through the transmembrane channels of ATP synthase and ATP is synthesized. There is no reduction of NAD+ or oxidation of NADH during chemiosmosis.
As the plasma cells begin secreting antibody, the antibody titer begins to rise. Eventually , the primary response will make an immune memory of the antigen.
IgM is not the first class of antibody which appear on the surface of developing B cell. It is the major class which secreted into the blood in the blood int he early stages of primary antibody response, which expose to antigen. Primary antibodies occur during the first encounter with virus.
All adaptive immune responses develop in steps, which consisting antigen recognition, activation of specific lymphocytes to proliferate , with the memory cells being the long live survivor.
