Answer:
The mass of a star determines its life cycle, that is, more the mass, shorter will be its life cycle. The mass of the star is determined by the concentration of matter, which is found within its nebula. In the nebula, with time, the hydrogen gas comes in close proximity with each other due to gravity and starts to spin.
With the brisk spinning, the gas heats up and turns into a protostar. The temperature now reaches 15,000,000 degrees and within the core of the cloud, the phenomenon of nuclear fusion takes place. The cloud now contracts a little, starts to glow brightly, and turns stable. The cloud now becomes a prime sequence star, and will stay in this phase for millions of years, the Sun of our galaxy is in this stage at the moment.

Answer:
Employee boredom
Explanation:
When an employee specializes in a specific part of job, and it tends to be repetitive each day, it leads to Employee boredom
. Therefore, there should always be novel challenges and tasks in work place which do not make an employee feel boring about same monotonous work each day in which they are already specialized.

Answer:
Symbiotic relationship
Explanation:
An average human body between 20 to 30 year of age with a weight of 74 kg and 170 cm contains about 30 trillion cells. The number of bacterial cells in the same man counts for about 39 trillion that is higher than the cell of the body.
The ratio between the bacterial cell to the human cell is about 1.3:1 which is almost equal or higher than the human cells.
Although the number of bacteria is almost equal or higher than the human cell, the main reason behind this relation is that these bacteria live in the symbiotic or mutually beneficial relationship with humans.
Thus, a Symbiotic relationship is the correct answer.
