Answer:
a. Recall and master the procedure in using a salinometer
Explanation:
Salinometer, which is also known as salimeter is a laboratory equipment used to measure the salinity of a solution. Salinity refers to the concentration/amount of salt in a solution.
According to this question, a student was instructed by his/her teacher to measure the salinity of brine used in curing fish. This means that to do this, the student will have to make use of a SALINOMETER. In order to use the salinometer, the student has to recall and master the procedure in using a salinometer.
Answer:
- Yeast - Fungi
- Penicillium - Fungi
- Rhizobium - Monera
- mushroom - Fungi
- Amoeba - Protozoan
- fish - Animalia
Explanation:
The Fungi Kingdom is a kingdom composed, as the name says, of fungi, which are organisms represented by many species, among them: yeasts, mushrooms, molds, Penicillium and others. As you already know, fungi are eukaryotic and multicellular organisms (with the exception of yeasts).
The monera kingdom is the kingdom formed by bacteria and also has several species as members. Among these species we can mention the Lactobacilli, Escherichia coli, Rhizobium (nitrogen-nodulating bacteria, very important for the natural fixation of nitrogen in legumes), among others.
The kingdom of protozoa is very diverse and even has an organism that does not have any type of genetic, structural and morphological similarity, but in most cases, the members of this kingdom are heterotrophs, eukaryotic and unicellular organisms. An example of this is amoebas.
The animal kingdom is made up of all animals, the most diverse and populous kingdom. All animals belong to that kingdom, including fish.
<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>
C. The sum of all forces on an object in equilibrium is zero. Equilibrium means in a stationary position. Therefore there is no acceleration. And using Newton's second law, we can say that the net or resultant force is 0.
F = ma
=>F = m(0)
=>F= 0
The two ultimate sources of energy for all living things on earth is sun light and certain rich compounds like chemotropes.
