I said in comment but the answer is
Pyramid of Biomass
Good luck on your assignment dear ^^
Answer:
B. the similarity in size between the cytosolic ribosomes of prokaryotes and the ribosomes within mitochondria and chloroplasts
Explanation:
Endosymbiosis explains the origin of mitochondria and chloroplast from the prokaryotes that were capable of carrying out aerobic respiration and oxygenic photosynthesis.
These prokaryotes entered the larger cells and eventually lost the ability to survive as individual organisms.
Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes. Being semi-autonomous organelles, both mitochondria and chloroplast also have DNA and ribosomes. The ribosomes present in these organelles are of 70S type. This theory is also supported by the presence of circular DNA in bacterial cells and in the mitochondria and chloroplast.
Answer:
b. He is missing a control group of mice that did not receive the new antibiotic.
Explanation:
He only has data that the antibiotic works, but not that it is more effective than existing treatments.
Answer:
A.
Protein molecules have many functions in the body, including the storage of genetic information.
Explanation:
One would expect to find silver carp DNA at Chicago site 2 if silver carp DNA is found at Chicago site 1 and North Shore sites 1 and 2 because they are within the same location and body of water and because silver carp are invasive species.
<h3>What is gel electrophoresis?</h3>
Gel electrophoresis is a analytical technique that is used in the of separation of the macromolecules such as DNA and their fragments based on their size and charge.
The DNA of silver carp was analyzed using gel electrophoresis.
The results of the gel electrophoresis of the silver carp DNA is as shown in the attached image.
Considering the results;
The gel bands of North site 1 and Chicago site 1 matched the positive control indicating that silver cap DNA was present in those site.
However there was no match for North site 2 and Chicago Site 2.
If you find silver carp DNA at Chicago site 1 and North Shore sites 1 and 2, then it is expected that silver carp DNA will be found at Chicago site 2 since they are found in the same location and because silver carps are invasive species.
In conclusion, the matching DNA bands indicates presence of Silver carp DNA at those sites.
