Plants and animals that share a often help each other survive. Plants provide food and shelter for animals. In turn, animals help plants reproduce. When bees and other insects gatherthey also carryfrom flower to flower. This helps tothe flowers. The of each flower then produces seeds and grows into a fruit. Other animals scatter the seeds.

biome or habitat, nectar, pollen, pollinate, propagation

Explanation:

Do any of these terms sound familiar?

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

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.
