This stadium can hold 100,000, or 1x10, people. The
Mekhanik [1.2K]

Answer:

1 x 10^13 stadiums will be needed in this scenario

Explanation:

We are told that

1 stadium holds = 1 × 10^5 people and

Number of iron atoms = 1 × 10^18 atoms

If the stadium carries an equivalent number of atoms as that of people.

We can infer that 1 stadium will carry 1 × 10^5 atoms.

The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.

Number of stadiums = Total number of atoms ÷ Number of atoms per stadium

= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium

= 1 × 10^13 Stadiums

This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums

Assume you inoculated 100 cells, with a generation time of 20 minutes, into 100 ml of nutrient broth. You then inoculated 100 ce
Marina86 [1]

Answer:

a) the same number of cells in both

Explanation:

In cells reproduction, in both cases we consider the same specie, the same generation time, and we assume the same broth.

The only advantage of the container with more milliliters of nutrients is that when the population increases, it will need more nutrients, so maybe the reproduction rate in the container with 100 ml will be lower.

But if the temperature, the quantity of nutrients are the same in both containers, so the volume is not a variable to affect the speed or low the reproduction rate.
