Answer:
Statement that is true about electromagnetic and mechanical waves is:
Option B: Mechanical waves must travel through a medium, but electromagnetic waves do not require a medium to travel.
Explanation:
'Electromagnetic' waves do not need any medium to travel whereas 'mechanical waves' need a medium or matter for transmission. Electromagnetic waves are produced by the 'vibrations' of the charged particles. They can even travel in vacuum.
On the contrary, mechanical waves are caused by the 'wave amplitude'. Mechanical wave can travel in solid, liquid and gas and are considered to be periodic disturbance.
Thus, Option B is the most statement apt explaining the difference between electromagnetic and mechanical waves.
Answer:
D). Diverse climates provided good conditions for growing a variety of crops.
Explanation:
The role that climate play in developing the ancient civilizations in East Asia would include the <u>'diversity of climates providing good and effective conditions for cultivation which eventually helped in gorwing a wide variety of plant groups</u>.' The elevation in latitudes led to the variation in air and wind blowing in different regions as well as the soil, rain, and temperature which proved to be a great source for growing distinct crops. Thus, <u>option D</u> is the correct answer.
Answer:
a. participant observation, diaries, and ethnographic interviews.
Explanation:
Participant observation: The term participant observation is defined as a method of qualitative research in which the experimenter observes the participants or subjects involved in the research as well as the experiment actively engages or involved in their activities.
Ethnographic interview: The term ethnographic interview is defined as a method of qualitative research that involves one-on-one interviews and immersive observation.
Diaries: The diary research is a form of qualitative research method that involves collecting qualitative data of the participants' activities, behaviors, and experiences over a period.
In the question above, since Super and Harkness are studying a developmental niche that can not be calculated or is an empirical variable, so it would be better for them to use qualitative methods to study. Therefore, it includes participant observation, diaries, and ethnographic interviews.
