Answer:
2, 4 and 5
Explanation:
The wall of Mycobacterium tuberculosis (a typical Mycobacterium) has a high lipid content, hence it does not respond to gram staining. Instead, acid-fast staining or Ziehl-Neelsen stain is used in its identification.
The cell wall of Mycobacterium species is thicker in comparison with other bacteria in the sense that it is hydrophobic, waxy and contains a unique acidic wax, known as mycolic acid.
Mycobacterium tuberculosis is an obligate aerobe, which means it is strictly dependent on oxygen. It thrives (multiplies) best under this condition.
Some species of Mycobacterium ate saprophytic i.e. they live on dead organic matter while some are obligate parasites that live on tissues e.g M.tubercosis and M.leprae causes tuberculosis and leprosy in humans respectively.
Answer:
Prions causes abnormal folding of the prion proteins in the brain.
Explanation:
Prions are the abnormal infectious agents composed only of the proteins and no nucleic acids. The prions cause several neurodegenerative diseases in the humans as well as the mammals.
The prions cause the cow mad disease in the cows by affecting the brain of the cow as the prions act on the prion proteins present in the brain only and change their conformation. This leads to the degeneration of the neurons and causes tiny pores in the brain giving sponge-like appearance.
This slows down the mental activity and thus ultimately leads to the death of the cow.
While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases oxygen
