A bacterium is made up of one single cell. An elephant is made up of many specialized cells. Which of the following statements is true? a. Bacteria are multicellular organisms, while elephants are unicellular organisms.

b. Bacteria are unicellular organisms, while elephants are multicellular organisms.

c. Both bacteria and elephants are unicellular organisms.

d. Both bacteria and elephants are multicellular organisms.

Statement B

Explanation:

Bacteria is made of a single cell where as elephants have many cells this becoming a multicellular organism

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

i'm pretty sure its b i might be wrong though!
