lana [24]

Answer:

The IgE antibodies bind to mast cells. The allergen cross-links them. This triggers the mast cells to release powerful chemicals like histamines.

Oxana [17]

Answer:

  147 to 161 bpm

Explanation:

The appropriate formulas are ...

  220 - age = maximum heart rate

  ⇒   220-32 = 188

  Maximum heart rate - resting heart rate = heart rate reserve

  ⇒  188 -52 = 136

  (Heart rate reserve X training%) + resting heart rate

  ⇒   136 × {0.7, 0.8} +52 = {147.2, 160.8}

John's target heart rate range is 147 to 161.
