Answer: This was an EXPERIMENT.

Explanation: An experiment can be defined as an examination under inhibited conditions made to examine the validity of a hypothesis, demonstrate a known truth, or determine the efficacy of something that has not been tried before.

In this question, the researchers applied the fertilizer to some parts while they didn't apply to some other parts. This act, is a quality of an experiment in the sense that the test was done under inhibited conditions. If the fertilizer was applied everywhere, it can be an observational study.

Answer: It's an EXPERIMENT

Explanation: Experiment is done when we apply anything to a samples or conditions in other to study another sample or conditions.

Observation is done when, we study samples or conditions in it's natural way, without application of anything that may alter it's result.

Because the researcher has applied fertilizer to one side and did not apply to the other side, that means he has performed an experiment. Since he wasn't observing the two sample in it's natural way without any external application.

Fever in infants and young children is not an uncommon event. Many trips to the pediatrician’s office occur because of fever in
mrs_skeptik [129]

Answer:

Every symptom is not a fever symptom in infants.

Explanation:

Fever occurs when the internal "thermostat" of the body increases the temperature of the body above its normal range.

A child's normal temperature varies with his or her age, activity, and even time of day.

Infants usually have greater levels of temperatures than children of more than 1-2 years. They may have higher temperature during late afternoon and early evening. Temperatures might be low between midnight and early hours of the  morning. Checking temperature with palm on the forehead should not be the way to decide if the child has fever. Always use a thermometer to check body's temperature and conclude whether it is fever or not.
