The “bases” of RNA differ from those of DNA in that thymine (T) is replaced by uracil (U) in RNA. ... In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).
Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division. Some of these features are holdovers from the ancient ancestors of mitochondria, which were likely free-living prokaryotes.
I think the answer would be needs. Hope this helps.
Answer:
In species with polyploid, there are more chromosomal sets than in diploid one. Becouse there are more chromosomal structures available, events like mutation, recombination, DNA lose, are more probable to occur.
As the generations pass, the accumulation of these changes tend polyploid to speciation.
Answer: The correct answer is- Converts solar energy to chemical energy.
Photosynthesis is a process of formation of food by green plants and algae using CO₂ and H₂O in the presence of sunlight. In this process, energy from sunlight is absorbed by chlorophyll ( green pigment present in the chloroplast) and it is converted into chemical energy in the form of ATP and NADPH. This is further utilized in the formation of food that is a carboydrate ( glucose).
