Explanation:

The sequence of steps in the breakdown of hemoglobin arae:

1. The heme of hemoglobin releases the iron.

2. The heme then converted into biliverdin.

3. The biliverdin which is converted into bilirubin.

5. Bilirubin is broken down to Hemoglobin.

5. Hemoglobin is broken down by macrophages into heme and globin chains

1. The heme of hemoglobin releases the iron. The heme then converted into biliverdin, which is converted into bilirubin.

2. Conjugated bilirubin is excreted as is then part of the bile into the small intestine. Bacteria of the intestine break down the bilirubin.

3. Some bilirubin derivatives converted into which is contribute to the color of feces.

4. Other biliurbin derivatives are reabsorbed from the intestine into the blood. These derivatives are excreted from the kidneys and contribute to the color of urine.

5. The globin chains of hemoglobin are broken down to individual amino acids and are metabolized or used to build new proteins.

6. Blood transports free bilirubin to the liver.

7. Blood transports iron in combination with transferrin to various tissues for storage or to the red bone marrow where it is used in the production of new hemoglobin.

8. Hemoglobin is broken down by macrophages into heme and globin chains.

The graph of x^2=-2+y+5cosy is shown for y=11

erik [133]

(a)

We have been given an equation $x^{2}=-2+y+5cosy$ . Upon taking derivative of this equation with respect to x on both the sides, we get:

$2x=0+\frac{dy}{dx}+5(-siny)\frac{dy}{dx}\\2x=(1-5siny)\frac{dy}{dx}\Rightarrow \frac{dy}{dx}=\frac{2x}{1-5siny}$

(b)

In order to write the equation of tangent line, we need to find the slope of the line. We know that point (3,11) lies on the graph. Therefore, we write the slope of the tangent as:

$\text{Slope}=\frac{dy}{dx}=\frac{2(3)}{1-5sin(11)}=1$

Therefore, equation of tangent line is:

$y-y_{1}=m(x-x_{1})\Rightarrow y-11=1(x-3)\\y-11=x-3\\y=x+8$

(c)

We know that slope of tangent is given as $\frac{dy}{dx}=\frac{2x}{1-5siny}$ . The tangent will be vertical when denominator of slope is zero, that is:

$1-5siny=0\Rightarrow siny=\frac{1}{5}\Rightarrow y=arcsin(\frac{1}{5})\\y=1.732,1.525, 3.063 \text{ etc.}$

Rachel refuses to share a room with a heavy roommate, and she voted against inviting a heavy person to join a group to which she

ikadub [295]

1. Rachel’s prejudice violates the requirements of critical thinking because she didn’t even try to get to know his character and how he is as a person. She has stated that “heavy people tend to be lazy and dishonest.” 2.) her prejudice violates the requirements of critical thinking due to having an opinion about him from the get go. Her views wouldn’t have changed if he was a good or a bad person because of having assumptions like “she would not hire an overweight person or trust one.”
