Answer: Bacterial species where observed Typical number on cell Distribution on cell surface
Escherichia coli (common pili or Type 1 fimbriae) 100-200 uniform
Neisseria gonorrhoeae 100-200 uniform
Streptococcus pyogenes (fimbriae plus the M-protein) ? uniform
Pseudomonas aeruginosa 10-20 polar
Explanation:
Pili are structures that extend from the surface of some bacterial cells.
These are hollow, non-helical, filamentous appendages.

The 0.05 moles of 
required to make 1 L of solution in which the 
concentration is 0. 15 M.
Calculation,
The Sodium phosphate dissolves as follows:
→ 
To make 1. L of solution in which the 
concentration is 0. 15 M
The morality of = 0.15 M = number of moles / volume in lit
The morality of = 0.15 M = number of moles /1 Lit
number of moles of = 0.15 mole
The mole ratio is 1: 3
It means, the 1 mole of required to form 3 mole of
So, to form 0.15 mole of = 1×0.15 / 3 moles of required.
Hence, number of moles of required = 0.05 moles.

Circumpolar stars
Explanation:
Stars which appears to revolve around the Polaris and do not set or go below the horizon are called circumpolar stars.
In short, this stars circles the pole.
- Circumpolar stars are not found at the equator.
- These stars do not set and they are visible at the north poles.
- The simply stay as the earth spins on its axis.

I think is NO because lowering the temperature increase of kinetic energy therefore kinetic energy is inversely to temperature.
