Answer:
Mitochondria originated when an ameoba like organism engulfed an aerobic proteobacterium capable of cellular respiration.
Explanation:
Endosymbiotic Theory:
- The endosymbiotic theory explains the origin of eukaryotic cells and eukaryotic organelles, particularly the chloroplast and mitochondria.
- According to this theory, a prokaryotic ameoba like organism increased in size and gradually developed infoldings of its plasma membrane. These infoldings gradually developed into an endomembrane that enclosed the genetic material and nucleus.
- This cell then engulfed a proteobacterium capable of cellular respiration. Over time, this cell thrived as oxygen increased in the atmosphere of the Earth. The proteobacterium survived as an endosymbiont and later evolved into mitochondria.
Metaphase happens after prophase.
Answer:
The feathers/scales are genetically modified and inherited from their previous ancestors which the feathers/scales drastically become different colors throughout the evolution of the bird/snake.
Explanation:
Solution :
It is given that BigMoney Inc. had a major spill of an inorganic which contaminated the soil around the plant. The scientist in the BigMoney had developed a mechanism to remove the from the soil but they did not found any for the .
The reaction is :
a). So this is an oxidation reaction as in the reaction the hydrogen atom is removed from the molecule.
b). The acts as an electron donor as it is being oxidized. Any substance that oxidizes is called an electron donor.
c). The above reaction can be carried out by aerobic respiration and the enzyme that is involved is hydrogenase which consumes and it releases a proton out of the cell. The reaction can often occur in our biological cells. This is fermentation that is used in the anaerobic as well as aerobic respiration process.
d). In the production, the electron donor is hydrogen that is organic as the hydrogen will be used from the air or the soil. And the pathways will be chemolithotrophy or fermentation.
