In groups of no more than 4. Use your notes from cellular respiration and photosynthesis to draw a diagram of carbon dioxide
(CO 2 ) and oxygen (O 2 ) in the environment. Your diagram must include at least one animal and one
plant. You will be graded for having each of the following in place and correct:
- All raw materials of cellular respiration and how animals get those materials
- All products of cellular respiration
- All raw materials of photosynthesis and how plants get those materials
- All products of photosynthesis
- Arrows indicating whether substances are moving in or out of organisms
Example: One part of my drawing would show O 2 from the environment entering an animal when it
inhales by an arrow from O 2 in the environment to the animal’s nose. How did the O 2 get in the
environment?

answer; ///(d) the correct answer is double or triple

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

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

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.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
