--- are tiny structures that make up all living things and are the smallest units able to perform life function. Unable to be seen with the naked eye, cells are . Some organisms such as amoeba and --- are single cell --- . Although we cannot see with our eyes alone, scientists can grow cultures in a lab or observe models that are enlarged or not to --- .

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

the answer is symmetrical : )
