The left ventricle is responsible to bump the blood through the body, and the right ventricle is responsible for the blood circulation in lungs, the size of them is determined by the resistance of the blood flow through which they have to pump. Body parts have much more resistance and need more pressure to pump through than lungs. Thus they are more muscular.
The answer is A) the mantle
Hi!
I would use system of equations to solve this.
Let r = calories per cup of raisins and s = calories per cups of sunflower seeds
I would set up the two equations as one being 2 cups of sunflowers + 3 cups of raisins = 2900 calories, and one cup of raisins + 400 calories = one cup of sunflower seeds. Those written out as equations are:
2s + 3r = 2900
r + 400 = s
Now, you can use substitution, substituting r + 400 into the first equation for s (as that equals s in the second equation) and you get:
2 (r + 400) + 3r = 2900
Now solve.
2r + 800 + 3r = 2900
5r = 2100
r = 420 calories
(For the check, for one cup of sunflower seeds, there are 820 calories, based off the fact raisins have 400 less calories than the sunflower seeds)
To check:
2 (820) + 3 (420) = 1640 + 1260 = 2900
420 + 400 = 820
So our answer of 420 calories is correct.
Hope this helped!

Schwann Robert Hooke
Explanation:
He discovered a honeycomb like structure in a cork slice using a primitive compound microscope. He only saw cell walls as he was looking at dead tissue. Hooke coined the term "cell" for the individual compartments he saw
