Because both eat primary consumers.
Answer:
Cell organelle
Explanation:
The cell organelle is the small organ-like structure present inside the cell in the cytoplasm.
Different types of cell organelles are present in the cell which performs specific functions like of storage, of digestion of biomolecules like lysosomes, of protein synthesis and many others.
The organelles are usually enclosed by either a single phospholipid membrane like in lysosomes, Golgi apparatus or two lipid layers like in nucleus and chloroplast.
Thus, cell organelle is the correct answer.
It seems you mean 1x10^9 because there are a lot of capillaries indeed. The answer I got is v = 1.65788 * 10^9 meters / second
Given:
vessel diameter = D = 8um
r = D/2 = 4um
v = velocity of blood flow is equal to cardiac output / total capillary area
So, v = Q/A
Where:
Q = cardiac output = 5 liters / minute
A = total capillary area = pi(r^2) multiplied by the number of capillaries
Solve A = pi(r^2) x 10^9
A = pi(4um^2) x 10^9
= pi(16um^2) x 10^9 = 50265000000 um^2
Convert to meters. You will get 50265 m^2
Since velocity uses a meters/second unit format, you should convert Q to something more applicable.
Q = 5 Liters / minute
= 5 L/minute x 0.001 cubic meter/ 1L
= 0.005 m^3/minute
Combine them all and you will get:
v = Q/A = (0.005m^3 / min) / 50265 m^2 = 0.005 m^3 / (min)(50265 m^2)
Then convert minute to seconds, and cancel out m^2 with m^3.
v = 0.005m / 50265 minutes (1minute / 60 seconds) = 0.005m / [60(50265)] seconds
v = 0.00000000165788 meters / second
= 1.65788 * 10^9 meters / second
