Answer:
Yes, it is estimated that there are about one trillion microbes species on earth, and we have not been able to isolate 99.99% of them, so, the knowledge is very limited. There is an study approach called METAGENOMICS. In Greek, meta means “transcendent.” It is a research field that allows to study comunities from their total DNA. It is, you can extract and sequence DNA from a sample, and find out about the composition of the population in there, even the interactions between them, with no need of pure culture.

Answer:
The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists. With the light come heat.
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.
The amygdala is found in each temporal lobe and is involved with the limbic system. The amygdala is found in the medial temporal lobe, immediately prior to the hippocampus. The temporal lobes are the second biggest lobes, located behind the ears. They are most typically related with the processing of auditory information and memory encoding.
The temporal lobes' primary roles include language comprehension, memory acquisition, face recognition, object recognition, perception, and auditory information processing amygdala. The temporal lobe is in charge of understanding and assigning meaning to different sounds. As a result, injury to the left temporal lobe often leads to issues understanding language.

Answer:
B. G1, S, G2, Mitosis, Cytokinesis
Explanation:
G1 is the first stage of the cell cycle, and it is essential for cell growth.
Next, the S (Synthesis) phase occurs. This phase involves DNA synthesis to prepare the cell for division.
G2 is the next phase, and it involves preparing and growing the cell for mitosis.
Mitosis is the next stage, where the cell divides into 2.
Lastly, Cytokinesis occurs after mitosis, and it creates the two daughter cells.
So, the correct answer is B. G1, S, G2, Mitosis, Cytokinesis
