B) False Because they are not compartmentalized within organelles.
Cytokinesis divides the cytoplasm of a parental cell into two daughter cells
In the treatment applied to dogs, in 22% of the dogs, the cell specialization process was not successful because the stem cells did not improve the arthritis problem
Stem cells are a type of cell that can transform into any of the 44 types of cells in the body, in a process called cell specialization. For instance:
- Neurons
- Sperms or ovules
- Pneumocytes
- Cells of the epidermis
Cell specialization is a term that refers to the process in which stem cells change from one cell type to another, stem cells modify their genetic expression, acquire specific morphology and functions.
According to the above, the treatment process that was not successful in 22% of the dogs was the cell specialization process, so they could not become the type of cell required to improve the condition of the dogs.

Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.
