<span>Empirical studies are results of analysis of data based on actual observation or experiences in the field. When conducting an empirical study, quantitative and qualitative approaches are employed, including:</span>
<span>1. </span><span>Providing data</span>
<span>2. </span>Emphasizes features of a new condition
<span>3. </span>Describes the current status of existing condition
<span>4. </span>Highlight associations between variables, but cannot establish causality, and
<span>5. </span>Suggest hypotheses which can be tested in analytical studies
<span>Qualitative empirical studies provide deep contextual data to help us understand a situation, but it cannot be used to establish its prevalence or incidence. It cannot be generalized also to highlight the statistical relationship between variables. If the aim is to measure the relationship, the quantitative methods should be used. A cross-sectional survey with large sample size is needed to describe the who, what, and where of a situation. Still, it cannot answer the why question. In order to answer the question of "why", an analytical or experimental study is needed. Experimental error is an important consideration here considering lapses or inaccuracies in the qualitative and quantitative data. </span>

.Answer:
Option A, fix nitrogen inside nodules on the roots of legumes
Explanation:
Rizhobium bacteria live in symbiotic relationship with roots of leguminous plants such as pulses including alfalfa, soybean etc.
Rhizobium or Bradyrhizobium is a gram negative bacteria that satisfies the nitrogen starvation of host plant.
These bacteria get habitation and nutrition from these leguminous plants and in return they fix the nitrogen into the nodules of the roots. This is a kind of facultative association between soil bacteria rizhobium and legume plants.
Hence, option A is correct
Thus, option A is correct
Answer:
<em>The child with the blood type O will be adopted. </em>
Explanation:
A punnet square can be described as a diagram which is made to depict the outcomes of a cross.
To determine the possible blood groups of the children with parents having AB and O blood group, lets make a punnet square:
O O
A AO AO
B BO BO
The punnet square shows that the children produced will have 50 percent chance of having A blood group and a 50 percent chance of having a B blood group. Hence, we can tell that the child with O blood group is adopted.
