Answer: chromatin condenses into chromosomes and can be best observed in prophase.
Explanation: chromosomes can’t be visualised by a light microscope except during cell division (mitosis or meiosis). The individual chromosomes become visible as the chromatin is wound tightly and are most clealry seen in late prophase.
Oxygen.
Oxygen was fatal when organisms started using photosynthesis, this event was known as the Great Oxidation Event.
Answer:
Rough endoplasmic reticulum extends from the nucleus to the cell membrane and holds ribosome at its surface.
Explanation:
Endoplasmic reticulum is of 2 types rough endoplasmic reticulum and smooth endoplasmic reticulum.
Rough endoplasmic reticulum is named so because it contain ribosome on its surface as a result rough endoplasmic reticulum play a significant role during translation or protein biosynthesis.
Rough endoplasmic reticulum extends from the nucleus that"s why most of the proteins of rough endoplasmic reticulum is accessed by the nucleus and if any proteins of RER or rough endoplasmic reticulum is not properly folded or misfolded then specific signals are send from nucleus for the correct folding of proteins of RER.
Solar power would, without doubt, be the most efficient type of power plant to build in this specific location. This is due to the fact that solar power produces no pollution in an environment. Also this type of alternative energy fits this communities resources due to the fact that the community receives primarily sun , a huge component in solar power, and little cloud coverage only increases the sun's power that much more. On the other hand, biomass needs things like wood, crops and alcohol fuels to burn in order to produce energy, some of which are not viable in this type of community because a place with little to no irrigation sources and an abundant amount of sunlight would be hard to produce any kind of natural aspect. Lastly, hydroelectric energy would not be a efficient of even viable choice because this community has no natural water available at hand to use for this alternative energy to function, and hydroelectric works primarily on a water storage.
