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.
Answer:
Rodents and primates.
Explanation:
Given diagram represents a phylogenetic tree, which shows evolutionary relationships between organisms. The nodes in the tree denotes the ancestral lineage, while the tips of its branches denotes descendants evolved from that ancestor.
According to given tree, rodents and primates share most common recent ancestor as these branches are evolved from a common node and so, they are most closely related organisms.
