If you were in spaceship and fired a 100kg probe into frictionless space, how much force would have to be Exeter on the probe to keep it going for 1000 years?

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the rearrangement of particles in a physical change. hope this

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =

80cm/s.

24cm/s.

53.3cm/s.
