Aerobic respiration is a chemical process inside cells which uses oxygen for the production of energy in the form of ATP. The waste products are carbon dioxide (CO2) and water (H2O). Aerobic reaction takes place within the mitochondria (inner membrane) and it consists of few steps: link reaction, citric acid cycle (or Krebs cycle) and the electron transport chain.
A hypothesis becomes a scientific theory when it has been thoroughly tested, and when whoever made the hypothesis now has proof of why their hypothesis was correct/incorrect.
If one factor changes biotic or abiotic it can hurt the ecosystem
Answer:
Asexual reproduction is a method of reproduction for most of single cell organisms including yeast, in this type of reproduction a single parent generates new organism and new one is exact copy of parent both physically and genetically.
In yeast asexual reproduction is carried out by budding, its an asymmetric type of division in which first a protruding body is produced on its surface, it fully grows and forms bud later. When full grown, buds detach from the parent cell and grows independently. Instead of single bud, a chain of buds could also be produced at the surface of yeast.
