When the fish is put into fresh water, suddenly the concentration around them is very low and the water potential is extremely high. Water will now move from the relatively high water potential in the water to the relatively low water potential in the cells, the cells start to burst and the fish dies.

Enkephalins and endorphins are peptides that act like morphine. True or False
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.

Enkephalins and endorphins act on the  mu, kappa , delta receptors and morphine also acts on the same receptors. All of them has same effects on the body.

Hence, Enkephalins and endorphins are peptides that act like morphine.

pentagon [3]

Answer:

Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length

Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length

The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).  

The inference procedure uses the information collected from the sample in order to obtain one conclusion.  Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
