<span>Performance = 70.443 + 4.885 * (time)
P = </span><span>70.443 + 4.885 * 2.6
P = 70.443 + 12.701
P = 83.144

P - 16 = 83.144 - 16 = 67.144

Answer:

67

Explanation:

Step 1: Insert 2.6 hours for the variable of time and solve.70.443 + 4.885(2.6)70.443+ 12.701= 83.144This is Ann's EXPECTED exam score.  Because of the concert, Ann scored 16 points lower than this number.Step 2: Subtract 16 from Ann's expected score.83.144 - 16= 67.144

What is the electrical pathway of the heart, in order? NOTE- this includes pacemaker and conduction components.
s2008m [1.1K]

Answer:

The correct answer will be option A.

Explanation:

The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.  

This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.

Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.

Thus, option-A is the correct answer.

The solutions in the two arms of a U-tube are separated by a membrane that is
IgorC [24]

Answer:

See the answer below

Explanation:

Recall that: <em>Water potential = pressure potential + solute potential</em>

Since the system is an open one;

<em>Water potential = solute potential = -iCRT</em>

i = number of particles the molecle will make in water (1)

C = molar concentration

R = Pressure constant = 0.0831 liter bar/mole K

T = temperature in kelvin = 22 + 273 = 295 K

To calculate water potential on side A:

C = 1 M

Water potential = - (1 x 1 x 0.0831 x 295) = -24.51 bars

For side B:

C = 2 M

Water potential = - (1 x 2 x 0.0831 x 295) = -49.03 bars

b.

<em>Since side A has higher water potential than side B, water will flow from side A to side B until equilibrium is established between the two sides. Water always flows from the region of higher water potential to the region of lower water potential.</em>
