The paragraph describes mitochondria and chloroplasts. Which sentence in the paragraph provides the strongest evidence for the e
ndosymbiotic theory of the origin of eukaryotes? Mitochondria and chloroplasts are organelles of eukaryotic cells.Mitochondria are involved in energy generation and are present in almost all eukaryotic cells. Chloroplasts are involved in photosynthesis and are found primarily in plant cells. In both organelles, reactions involved in the transfer of energy take place along the organelle's folded inner membrane. Both organelles can direct their own replication by splitting through a process similar to binary fission.
The correct answer is both organelles can direct their own replication by splitting through a process similar to binary fission.
Explanation:
Endosymbiotic theory explains the formation of organelles like chloroplast and mitochondria which evolved miliion of years ago by engulfing the phototrophic and chemotrophic bacteria respectively.
Evidences that support their endosymbiotic relation is that they
1. Both chloroplast and mitochondria contains their own genetic material-DNA.
2. They divide with the same mechanism used by the bacteria that is binary fission to form two daughter cells.They have their own prokaryotic replication machinary to start replication. Therefore, fission and replication are coordinated with each other.
Thus, organelles divide by binary fission is the correct answer.
This shows that these organelles were once free-living organisms with their own mechanisms for reproduction which they have retained even after years of symbiotic relationship with the higher organisms. During their duplication, they also replicate their own DNA. Their DNA does not have histones (as opposed to the DNA in the nucleus of their host eukaryotic cell) similar to that of simple organisms such as bacteria.
<span>C. neutral, with the number of protons equaling the number of electrons. is the right answer because number of neutrons vary from atom to atom</span>
<span>well photosynthesis uses sunlight to split H2O and pass on an electron pair to plastoquinone (photosynthesis II) and to NADP+ -> NADPH (photosynthesis I). Also phosphorylation of ADP to ATP..
idk what they mean by recycling.. it would be H2O and CO2 that they "recycle" if anything. </span>
The things that Sarah needs to know include the size of the pizza as well as the crowd capacity and how many slices come with each pizza. In this case, we can say that she would need at least 2 boxes of pizza for all the people in the gathering to have at least one slice or 4 to 5 boxes from them to have at least 2 slices each.
