Bogdan [553]

Answer:

The correct answer is option b, that is, four-field approach.

Explanation:

Anthropology refers to the study of human beliefs, behavior, and adaptations. In order to completely comprehend any aspect of human behavior, the field of anthropology adopts a four-field approach. The four sub-disciplines of anthropology are archaeology, cultural anthropology, biological anthropology, and linguistic anthropology.  

In archaeology, materials are used generally from past cultures, in order to understand and illustrate human behavior and adaptive strategies via time. Biological anthropology refers to the study of humans as biological species, the research areas comprise diversity in modern human populations, human evolution, and medical anthropology.  

The cultural anthropology explores patterns of behavior and belief in historical and contemporary cultures all over the globe. The linguistic anthropology studies and documents languages in terms of acquisition, structure, and use in the transmission of culture. As can be seen that each of the sub-disciplines focuses on distinct characteristics of human adaptation, however, when taken together in a four-field approach it offers a powerful tool for gaining a complete understanding of any aspect of human behavior.

A postitivly charged atom has? A.Lost electrons B. Lost protons C.Gained electrons D.Gained protons
Kipish [7]

Not to be too picky, but the question ought to say a positively charge ion rather than atom.

I will assume that is what you mean. An ion, using ordinary means, will be positive if it loses electrons (which are negative).

An ion can never gain protons. Left alone, the nucleus will remain unchanged for the rest of eternity. D is wrong.

C is wrong. If electrons are gained, the ion will go negative.

B is wrong for the same reason D is. An ion can't gain protons and it can't lose them.

A is the answer.
