Answer:
A. Ribosome
Explanation:
Ribosome is a sub cellular structure, that is involved in protein synthesis.
Mitochondria is a sub cellular structure, where cellular respiration takes place, therefore it is called the energy house of the cell.
Cytoplasm is a jelly like structure in which sub cellular structures are found.
Nucleus is the main part of the cell in which all cellular activity is controlled by.
It contains DNA and RNA.
Nucleus is mostly known for it's thread like structure that contains hereditary information which is passed from parents to offspring.
Hope it helps ;) ❤❤❤
To test the effectiveness...
A. This variable should be controlled (the same in both groups).
B. The new chemical is what is being added to the experimental group.
C. This is the control group to which the treated couch should be compared.
D. This is the experimental group to which data should be taken.
Final answer: D
Answer: Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Explanation:
Answer:
It adjusts to different oxygen levels.
The cytochrome bo branch operates when E coli is growing rapidly with good aeration.
The cytochrome bd branch operates at low oxygen conditions. It is located in the outer membrane.
Explanation:
Electron transport chains of Escherichia coli are composed of different dehydrogenase and terminal reductase which is linked by quinones. It adjusts to different oxygen level because Oxygen is preferred electron acceptor and represses the terminal reductase of anaerobic.
