Answer:

The elbow is considered a third class lever because the effort is applied closer to the fulcrum than the load.

Explanation:

On a third class lever the power exercised is between the point of support and the resistance.

The elbow is the joint between the arm and forearm, similar to a clamp, performing predominantly flexion and extension movements.

The elbow joint is considered a lever of this type as:

  • It has its point of support in the joint itself,
  • Resistance is given by the weight of the objects that are lifted by the hand and,
  • Between both is the potency generated by the arm and forearm muscles.

In this case, the elbow is characterized because the effort is closer to the fulcrum - the elbow or point of support - than to the load.

<em>- The effort is applied further from the fulcrum than the load and the fulcrum is in the center of the lever correspond to other types of leverage.</em>

<em>- The elbow is used to lift objects, is a general function of the upper limb.</em>

How many milliliters o a nonmedicated, lavored syrup base must be added to 1 pint o ranitidine (ZANTAC) syrup, 15 mg/mL, to chan
stira [4]

Answer:

946.35mL (to 2 decimal places)

Explanation:

Use the formula

C1V1 = C2V2

where C1 is the concentration of the undiluted medication = 15mg/mL

           V1 is the volume of the undiluted medication = 1 pint = 473.176mL (convert pint to mL)

           C2 is the concentration that the diluted medication should have = 5mg/mL

           V2 is the volume of the diluted medication with syrup = ??

C1V1  = C2V2

15mg/mL x 473.176mL = 5mg/mL x V2

<u>15mg/mL x 473.176mL = V2</u>

        5mg/mL

1419.528mL = V2

V2 = 1419.528mL (expected volume of medication + syrup)

Therefore, amount of non-medicated flavored syrup base to be added = 1419.528mL - 473.176mL

             = 946.352mL (2 pints)

Vision is especially acute in the fovea and surrounding macula because of a high density of cone cells and because __________. V
SCORPION-xisa [38]

Answer:

Answer:

Anatomically  this is because  there are no neurons or blood vessels covering the cones.

Explanation:

Fovea centralis  and its containing  cones cell  is   surrounded by the  macula lutea  to form  a depression or pit in the retina. The  abundant cones cells provide high visual acuity characteristic of the fovea.

In addition  an area in the fovea of no  blood cells called fovea avascular zone   allows light rays to  be focused on the fovea, with less scattering,this minimises the losses of incident lights on the fovea, and therefore  reception of  maximum light rays from objects for acute vision.

Therefore the presence of abundant cones cells in the fovea  together with the presence  of fovea avascular (area with no blood cells)which reduces dispersion of light rays for maximum receptions are responsible for high visual acuity  of the fovea.

This explains the reasons why fovea is refereed to as the  center  for primary vision  or fovea vision  where  high degree of visual activity is  needed   such as focusing with microscope, reading,knitting and driving
