Aerobic respiration requires oxygen to occur, and then it releases a large amount of energy. Anaerobic respiration occurs when glucose breaks down without any oxygen to produce a little energy, and lactic acid. Anaerobic respiration occurs when we exercise vigorously and the heart and lungs are not able to provide enough oxygen.
The large intestine's main function is to process waste.
I think the answer is D :)
The human Y chromosome is about 50 million base pairs long. One would expect to find 250,000 nucleosomes associated with this chromosome.
A nucleosome typically contains 200 base pairs. On dividing 50 million by 200, one would get 250,000 which would tell about the number of nucleosomes associated with the human Y chromosome.
A nucleosome is a segment of DNA that is wrapped around a core of proteins. A nucleosomes constitutes the repeating unit of a structure in nucleus known as chromatin (thread-like stained bodies present in nucleus).
The nucleosomes in chromatin appear as 'beads-on-string' when viewed under an electron microscope.
