Answer:
The correct answer is: Maggots do not arise spontaneously but from eggs laid by adult flies.
Explanation:
According to the experiment Redii, The maggots are present only in the open jar not in the sealed jar. The adult flies can not go in or out of the jar to the meat and can not lay the eggs on meat whereas in an open jar the adult flies can easily get in the jar and lay the eggs on meat.
On the basis of the above response and explanation, it can be concluded and hypothesize that maggots do not arise spontaneously but from eggs laid by adult flies.
Answer:
Serum potassium level of 2.6 mEq/L
Explanation:
Chemotherapy has many side effects like nausea, vomiting, diarrhea, fatigue, fever, etc. Vomiting and diarrhea can affect the fluid and electrolyte balance adversely in the body. This can lead to a reduction in the serum potassium level.
A low level of potassium in the body can lead to weakness, cramp, paralysis, twitch, abnormal heart rhythm, etc. The normal blood potassium level is 3.6 to 5.2 millimoles per liter so a serum potassium level of 2.6 mEq/L is the finding that indicates a chemotherapy-induced complication.
