Answer:
A. engulfing of small photosynthetic prokaryotes by larger cell
Explanation:
The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship.
Some Evidence for this is based on the following:
1. Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane.
2. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane.
3. Mitochondria and chloroplasts have their own DNA that is circular, not linear.
4. Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S.
5. Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.
<span> The answer is a misense mutation. In this case, the substitution of the tryosine amino acid with cysteine in the same position in the sequence does not affect the polypeptide becasue both tryosine and cysteine are polar animo acids. If the substitution </span><span><span> in the polypeptide chain </span>was by amino acids with different properties, it would affect the folding of the protein and change its conformation hence also affect its function. </span>

Prokaryotic and eukaryotic flagella <u>have different structures .</u>
<h3>What are Prokaryotic ?</h3>
Any organism without internal membranes is referred to as a prokaryote, usually written procaryote. One of the most well-known prokaryotic species is bacteria. Prokaryotes differ from eukaryotes by not having internal membranes.
Prokaryotic cells are those that lack membrane-bound organelles and have their genetic material floating freely inside of their cell wall.
All prokaryotic cells have a nucleoid area, ribosomes, which create proteins, DNA and RNA as their genetic material, and cytosol, which has a cytoskeleton and organizes cellular components. Prokaryotic creatures, on the other hand, are a tremendously diverse collection of living things and exist in a wide range of sizes and shapes.
