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.
The carbon rod in a standard D-cell serves as a conductor to dry-cell.
Hope help!
Answer:
true
Explanation:
photosynthesis is literally the transfer of solar energy into chemical energy so that plants can survive.
Answer:
a) Most alcohol is metabolized in the small intestine.
b) Food in the stomach slows the absorption of alcohol.
c) Alcohol inhibits the release of anti diuretic hormone, which can lead to dehydration.
Explanation:
About 80 % of alcohol is absorbed by the stomach while 20 % of alcohol is absorbed by stomach. Food materials such as lipids etc slow down alcohol absorption by the intestine because the valve that is present between stomach and small intestine is closed if food is present in the stomach. Alcohol decreases the release of anti diuretic hormone, so low water is removed from the body and reduce dehydration.
NO, the protein solution do not have a high morality. The protein solutions generally have lower molarities. This is because protein molecules are larger in size and do not form a soluble and uniform solution. Protein molecules do not dissolve in solutions.
