What happens during S Phase?
vampirchik [111]
S phase is the DNA synthesis phase. During this portion of the cell cycle, the cell replicates its entire complement of DNA. It also forms the centrosome, which is the microtubule-organizing center that will eventually help the cell pull apart the DNA that will be divided between daughter cells.

Do prokaryotic organisms carry out<br> cellular respiration? If so, how?
Stella [2.4K]

Hi

Do prokaryotic organisms carry out  cellular respiration? If so, how?

The answer is yes as well as no, because some prokaryotes like Archeae and some bacteria donot use cellular respiration because they are anaerobic. The Archaea are also known as Methanogens that reduce Carbon di oxide from environment to Methane that is eventually oxidized to NADH (that is used as an energy source).

However, there are some bacteria that use cellular respiration as a source for the energy production.Cellular respiration is a process which occurs in the cells of higher living organisms as well as in cells of some small organisms like Bacteria. During process of cellular respiration in bacteria, glucose is broken down with the help of oxygen into water and Carbon di oxide. In the process of cellular respiration, bacteria just like humans goes through three stepsi.e Glycolysis, Kreb cycle and Electron transport chain that ultimately lead to the production of ATP (energy).

Hope it helps!

This is an advantage of which map projection? They are similar to the actual spherical surface of the globe.
lisov135 [29]

Answer:

Azimuthal map projections

Explanation:

The Azimuthal map projections come in a circular shape. They represent the whole world but in a different manner than that of the other map projections. The other map projections tend to have problems with the size of the objects as they get further away from the Equator, but this map projection doesn't have that problem. The Azimuthal map projections actually represent all of the places on Earth with their correct distances from the central point, and they all have their sizes correct proportionally to the scale, thus making an accurate map projection.
