Stars begin to form from clouds of gas in space. The cold temperatures and high densities (compared to elsewhere in space, but would be considered a vacuum on Earth) of these clouds allow gravity to overcome thermal pressure and start the gravitational collapse that will form a star.
Answer:
A population is a group of organisms of the same species, in the same place
A species is a group of organisms that are genetically similar
Explanation:

As a species however, we are all over the place
Answer:
The correct answer is option B) "computers are not as trustworthy as actual prototypes are"
Explanation:
It is false to affirm that results obtained from computer simulations towards looking for solutions of real-world problems are not as trustworthy as results obtained from actual prototypes. In most cases, computer simulations had proved to be reliable, particularly when the programers use validating arithmetic and algorithms. There are multiple companies dedicated to develop computer simulations to solve real-world problems, which are constantly used and tested in scientific investigations.
