mariarad [96]

Answer:

True.

Explanation:

Enkephalins and endorphins are endogenous peptides while morphine is an exogenous peptide.

Enkephalins and endorphins are powerful analgesics 18 to 500 times more than morphine. Hence, morphine is less analgesic than enkephalins and endorphins.

Taya2010 [7]
Use binomial distribution with p=0.25, n=5, x=2
P(X=x)=C(n,x)p^x (1-p)^(n-x)

P(X=2)=C(5,2) 0.25^2 0.75^(5-2)
=10*0.0625*0.421875
=0.26367

So the probability of 2 of 5 children having type-O blood from these parents is 0.26367.
