They have adapted through the concept of natural selection
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.
<span>In order for the growth rate to remain constant, the birth rate must equal the death rate. This is the number of the population being born and the number of people dying. A birth replaces a death and vice versa, so if the birth rate and the death rate are the same, there are the same number of organisms total.</span>
B. double the haploid number of chromosomes
This is because these characteristics normally have a low survival value for the species. Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and more harmful traits to become rare. This occurs because organisms with advantageous traits pass on more of these heritable traits to the next generation.
