A. After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
C. Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
D. The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
E. Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice
Answer:
Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?
The correct answear is B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
Explanation:
Naltrexone is a non-selective opioid antagonist, it competes with these at the level of the receptors and thus reduces their effects.
The responses A, C, D and E does not weaken the support for the
researches ´ predictions, and are not relevant to the argument.

When the northern part of the earth is farthest away from the sun it gets cold and the other side of the earth gets warm / summer
Explanation;
The Earth's orbit is not a perfect circle, but a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away.
When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, because the Earth is tilted on its axis.

Correct answer: A) Procedural error
Procedural error is the error in which while conducting the experiment the scientist follow a wrong procedure which result in the negative result of the scientific experiment.
Example: While performing a experiment in which heating is required, procedural error occurs when a something is being heated a lid is not put on it, or missing a step, or heating it to a wrong temperature are the procedural error in the experiment which result in the negative result of the experiment.
