(a) Create a pie chart to illustrate the volumes of the various components of blood. (b) What challenges did you face when creating your chart?

When designing a cost system, what points should you consider before creating the design?

Solve. Round to the nearest hundredth.

$$x ^ { 2 } - 29 = 0$$

Simplify.

$$12 ^ { 2 }$$

Name at least four substances that are carried by the circulatory system

How does an angiogram differ from a regular X-ray scan?

Solve the equation. Check your solution.

$$\sqrt [ 3 ] { x + 5 } = 2 \sqrt [ 3 ] { 2 x + 6 }$$

Chiang said that a circle with the equation

$$(x + 2)^2 + (y - 5)^2 = 6$$

has a radius of 36. Explain and correct Chiang's error.

Explain how the circulatory system interacts with the digestive system

The line going through point M and perpendicular to line a intersects line a at point C. The coordinates of the points are given. Find the distance from point M to line a. M(8, -3), C(1, -11)

a. How long is an a-helix that contains 74 amino acids? b. How long is a fully extended peptide chain that contains the same number of amino acids? (The distance between consecutive amino acids in a fully extended chain is 3.5 Å; the repeat distance of an a-helix is 5.4 Å.)

Describe the function of the circulatory system.

(a) At what position in front of a spherical refracting surface must an object be placed so that the refraction produces parallel rays of light? In other words, what is the focal length of a single refracting surface? (b) Since real object distances are positive, what does your result imply for the cases $n_2>n_1$ and $n_2<n_1$?
