They both help to keep all of the gas and dust in place and not just float off. it evolved from a solar nebula. stars were created in the solar nebula and they would attract gas and dust and became bigger and bigger.
Answer:
They help digest food, make vitamins, and play other important roles. Humans also use bacteria in many other ways, including: Creating products, such as ethanol and enzymes. Making drugs, such as antibiotics and vaccines.
Answer:
The correct option is 'the ability to absorb other cells gave some prokaryotes a survival advantage.'
Explanation:
The scientists have brought forward the theory of endosymbiosis which explains how eukaryotic cells evolved from prokaryotic cells. According to this theory, the scientists claim that the organelles found today in the cells, once existed as individual prokaryotic cells. These organelles were engulfed by larger prokaryotic cells with time and hence, the eukaryotic cells evolved from these prokaryotic cells. The larger prokaryotes might have engulfed the smaller cells for survival.
I think the answer is: Food for the plant
Explanation:
The anaerobic respiration that is respiration which is involved in producing energy molecules like ATP without oxygen evolved earlier than aerobic respiration.
The anaerobic respiration undergoes glycolysis which produces pyruvic acid form lactic acid, ethanol, and very low amount of ATP. This anaerobic respiration is known as fermentation.
The fermentation produces a very low amount of ATP that is only 2 molecules but the amount is sufficient for the simple organisms to survive therefore the fermentation is still performed by the organisms.
