Answer:
naturalistic observation
Explanation:
In naturalistic observation, researchers will gather data by directly observing the subjects in their natural habitat without making any intervention.
This is what Professor Ober is doing.
Professor Ober wants to collect a data about development of their physical skills among children. This means that the <u>children are his research subjects.</u>
To collect his data, professor Ober observed the children in the playground (which is the children's natural habitat). He also did not told the children to do anything , he just quietly observe and let the children do what they usually do. (not making any intervention)

Answer:
Explanation:
1. Short reflexes are stimulated by stretching or chemical stimulation of the myenteric plexus, which can result in peristaltic contractions.
2. Long reflexes utilize the parasympathetic nervous system, specifically the Vagus nerve.
3. Hormonal secretions like gastrin and secretin are released into the blood and stimulate relatively distant parts of the digestive tract.
4. Paracrine secretions like histamine and prostaglandins diffuse through the tissue fluids and stimulate nearby target cells.
We can conclude the passage is from a medieval period because it includes a monarch that rules or has power over other social classes (third option).
One of the characteristics that made Medieval society to be different from other societies was its social structure. In this social structure, the monarchy represented by the king, queen, or prince was the most powerful social class.
This means this class had power over others including knights, noblemen, and peasants. This characteristic is shown in the passage because Prine John is announced with trumpets and seems to be protected and respected by others including "horsemen, horsewomen, and foot-passengers."
Note: This question is incomplete because the passage it refers to is missing; here is the passage:
About the hour of ten o’clock, the whole plain was crowded with horsemen, horsewomen, and foot-passengers, hastening to the tournament; and shortly after, a grand flourish of trumpets announced Prince John and his retinue, attended by many of those knights who meant to take share in the game, as well as others who had no such intention.
