Sati [7]

Option (D) flagellated protist is correct.

The last common ancestor of all animals was probably a flagellated protist.

<h3>What is a Protist?</h3>
  • Any eukaryotic organism that is not an animal, plant, or fungus is referred to as a protist.
  • The absence of other eukaryotes means that protists do not constitute a natural group, or clade, even though it seems likely that they all descended from a common ancestor.
  • Protozoa is another name for protists that resemble animals. Some are parasites as well.
  • The four phyla that make up the Protozoa are flagellates, ciliates, spore-forming protists, and protists that resemble amoebas.
  • Nuclear membranes surround the DNA of protists.
  • Most protists are motile, or able to move, and many of them inhabit aquatic settings.
  • Protists can reproduce sexually and/or asexually, and their life cycles are intricate.
  • Protists consume, absorb, or produce food through photosynthesis.

which of the following correctly compares fermentation and cellular respiration? a. both provide atp molecules, but only ferment
ruslelena [56]

Fermentation can be defined as the process that involves partial breakdown of sugar molecules into alcohol and lactic acid, in the absence of oxygen. It occurs in many bacterial cells, yeasts, and starved muscle cells. Whereas respiration involves complete breakdown of sugar molecules into carbon dioxide and water, in the presence of oxygen. It occurs in all living organisms. Respiration provides a large amount of energy as compared to fermentation as respiration produces 36 ATP molecules and 2 ATP molecules per glucose molecule.

Hence, the correct answer is 'option C - cellular respiration produces more ATP molecules than fermentation.'
