What is the term for the people who are interviewed in a research study
4vir4ik [10]

Answer:

QUALITATIVE INTERVIEWING IS MOST USEFUL FOR:

* Evaluating programs that are aimed at individualized outcomes

* Capturing and describing program processes

* Exploring individual differences between participants' experiences and outcomes

* Evaluating programs that are seen as dynamic or evolving

* Understanding the meaning of a program to its participants

* Documenting variations in program implementation at different sites

QUALITATIVE INTERVIEWING IS NOT AS USEFUL FOR:

* Evaluating programs that emphasize common outcomes for all participants

* Measuring specific, predetermined effects of a program on participants

* In impact evaluations, deciding whether your intervention caused changes or effects in participants (since determining causality requires more controlled conditions)

Explanation:

An interview in qualitative research is a conversation where questions are asked to elicit information. The interviewer is usually a professional or paid researcher, sometimes trained, who poses questions to the interviewee, in an alternating series of usually brief questions and answers.

In assembling a nucleosome, normally the …(1) histone dimers first combine to form a tetramer, which then further combines with
Readme [11.4K]

Answer:

option 1

Explanation:

In assemblying the nucleosome, this reaction occurs in two main steps. the H3 and H4 are recruited first to the DNA in pairs forming the H3/H4 tetramer; meaning two of H3 and two of H4. This gives rise to the nucleosome precursor. Then after this, the dimers of both H2A/H2B are recruited to this precursor, to give rise to the octamer structure around which the DNA is wrapped.

1. If the frequency of two alleles in a gene pool is 90% A and 10% a, what is the frequency of individuals in the population wit
Illusion [34]

Answer: 0.18

Explanation:

For the alleles, the percentage distribution of each is 'A' (90% = 0.9)

While 'a' (10% = 0.1)

Hence, 0.9 and 0.1 are the respective frequencies of each allele

Now, apply Hardy-Weinberg Equilibrium equation, where heterozygotes are represented by the 2pq term.

Therefore, the number of heterozygous individuals (Aa) is equal to 2pq which equals

2 × 0.9 × 0.1 = 0.18

Thus, the frequency of heterozygote is 0.18, while the percentage distribution in the population is 18%
