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:
The correct answer is C) 8 exons.
Explanation:
If we assume that each domain matches with an exon, and we have a 6 domain protein (domain= the functional regions of the protein that include the active site), there must be at least 6 exons in the gene. Also, remember that exons include the 5'- and 3'- untranslated regions or UTR. So, assuming that each unstraslated region is equivalent to an exon, there must be at least 8 exons in the gene (6 exon for each domain and one 2 exons for UTR).
Anyway, be careful, because this is a simple exercise where we assume a lot of things. In the real world, the first exon tends to include the 5'-UTR and it is already proved that one exon is not always equivalent to one protein domain.

You can determine that the deer population was reduced by 1, due to the losses being more than the gains. It can also be expressed as a math problem
6 - 5 - 3 + 1= -1
Answer:
1. Neisseria gonorrhoeae can be matched with Gonorrhea
2. Clostridium botulinum can be matched with botulism
3. Lactobacillus bulgaricus can be matched with yoghurt
Explanation:
- Gonorrhea is a sexually transmitted infection caused by a bacterium called
Neisseria gonorrhoeae. And it affects the urinary tract and genitals of humans.
- Botulism is a fatal condition of poisoning caused by a bacterium called Clostridium botulism
- Yoghurt is a edible food product made from milk, and curdle by the help of the enzyme, Lactobacillus bulgaricus.
