A problem with nonprobability samples is a. None of these are correct. b. one cannot assess the amount of sampling error likely to occur. c. there is no problem with using nonprobability samples d. All of these are correct. e. they are always more representative than probability samples.

The correct answer is A) Protista, Fungi, Plantae, and Animalia

Explanation:

In biology, there are six main kingdoms: Plantae, Animalia, Fungi, Protista, Archaebacteria, and Eubacteria. Each of these kingdoms includes unique organisms; however, there are also common features between different kingdoms.

In terms of cells, the Protista, Fungi, Plantae, and Animalia kingdom include Eukaryotic organisms (organism composed of cells with a nucleus), besides this, these Kidngoms include mainly multicellular organisms although there are also unicellular ones. On the other hand, Eubacteria and Archaebacteria kingdoms include only prokaryotic organisms which are unicellular organisms without a defined nucleus.

This implies, if a scientist finds a new life form and this is multicellular it can belong to Protista, Fungi, Plantae, and Animalia that include multicellular organisms, and it cannot belong to Archaebacteria or Eubacteria kingdom because these include only unicellular organisms.
