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.

Answer:
Carbon Cycle: the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
Explanation:
Pines, spruces, and firs are conifers
Explanation:
The enzymatic digestion of starch by amylase can be performed in the laboratory by several ways. But below there is an example of it
In order to have the best protein performance we have to set the temperature of the reaction to 37 celsius degrees.
- Prepare a starch solution and spread into tubes
- Prepare an amylase solution and spread into tubes
- Adjust the pH to the optimum range with buffers, that is about 6.7 to 7.
- Adjust the temperature of the tubes reaction to 37 celsius degrees.
The wrong temperature and the pH can unfold the enzymes and make the binding site inefficient.
- Pipette the starch solution in the tubes with enzymes.
By the final step the glucose will be produced by the enzymatic digestion of amylase.
