Biology
1 answer:
Sergeu [11.5K]3 years ago
4 0

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.

Arrows represent the forces applied to an object. A longer arrow means a greater force. Which object will move upward?
Katen [24]

Answer:

Object C

Explanation:

Object A has two arrows, one pointing up and one pointing down. Since both arrows are the same length, the forces cancel, and Object A will not move.

Object B also has two arrows, one pointing up and one pointing down. However, the downwards pointing arrow is much longer than the other. This means it has more force and the object will move down.

Object C has two arrows, one pointing up and the other down. However, the upwards pointing arrow is longer than the other, meaning it has more force and the object will move upward.

Object D has two arrows, but both are pointing downwards, meaning the object will move down.
