Answer:
b. They express the appropriate receptor.
Explanation:
The signal transductions are extraordinarily specific and sensitive. Specificity is achieved by a <u>precise molecular complementarity between the signal molecules and the recepto</u>r. For example, the thyrotropin-releasing hormone produces a response in cells of the adenohypophysis, but not in hepatocytes, which lack the receptors to this hormone.
The blood has low oxygen content
No flamingos dont normally migrate unless there are changes in their habitat conditions
C because it is thrown harder and has more thrust
If the student has mass 75 kg, and if the stairs are 3 m high, then
<span>work = mgh = 75kg * 9.8m/s² * 3m = 2200 J </span>
<span>so I'd say "one one-hundredth." </span>
<span>Except that I think 5000 cal ≈ 20.95 kJ (not J), and that would change my answer to </span>
<span>"ten times or so".
