When constructing an argumentative essay, incorporate sources that are or are close to irrefutable and have relevance to what you are discussing. For example, if your topic is about why sanitary napkins for women should be free at school then present facts about how not everyone has access to them at home or how the expense would not cost a lot. However, no matter what you say it can not be opinion driven and you must have valir reasons and statistics to support your point. So using the previous topic, I would mention the actual estimated price free sanitary napkins would cost or talk about the struggles of teenage girls or teachers who cannot afford tampons. Additionally in your argumentative essay, you will need a counterclaim which is you rebuting a popular misconception or a common opposing viewpoint. For example, one may mention how female students and faculty would abuse the privilege and would not use it for only emergencies. They would then combat the statement by highlighting how many schools that do offer free sanitary napkins obtained a specific system that allows them to monitor who is borrowing what and the quantity of how much they borrow by making the pads accessible at the nurse or the administration office. You will know if something supports your claim if the evidence has the same topic and main idea as your objective and if it does not disprove your belief.
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be: 9:3:3:1.
<h3>What is a phenotype ratio?</h3>
- The phenotypic ratio refers to the proportion of offspring that exhibit a specific trait or set of traits. A test cross can be used to ascertain the frequency of a trait or trait combinations that will manifest themselves based on the genotypes of the progeny.
- The ratio of various phenotypes found in a cross's progeny is known as the phenotypic ratio. Comparisons using numbers are ratios. For instance, the proportion of apples to oranges would be 3:2 if someone had three apples and two oranges.
- We examine the alleles of the parent organisms and predict how frequently the offspring will exhibit those genes to determine a phenotypic ratio. Most of the time, we are aware of the expression and appearance of the alleles.
- Phenotypes include things like height, wing length, and hair color. In addition to measurable traits that may be observed and tested in a lab, phenotypes also include blood cell or hormone levels.

Answer:
The answers are:
a. dependent
b. independent
c. test
d. control
Explanation:
In scientific research, investigations are done to study whether certain factors change while changing others, and the following terms are associated with scientific research:
a. dependent variable: These are factors or outcomes that are being investigated in a research experiment, and they are not under the direct control of the researcher. They are factors that vary as a result of other changes made in the process. In our example, the heart rate and blood pressure are proposed to vary with the type of film watched hence these factors are dependent variables.
b. independent variable: Independent variables are variables that are under the direct manipulation of the researcher, and the predetermined variation of these variables cause certain effects on the dependent variables. In our example, the type of film is the independent variable, because the researcher has complete control over the type of film watched.
c. Test group: These are the group of participants/individuals in research, who will potentially be affected by the change in the dependent variable to cause an effect that deviates from the normal. In our example, the group that views the violent film is the test group, because there is a tendency that they might have altered heart rate and blood pressure as a result of the type of film viewed.
d. control group: The control group is the group of individuals whose effects at the end of the experiments will serve as baseline effects, to serve as a means of measuring the magnitude of variation in the test group. These groups serve to eliminate any other effects that might cause similar changes as the factor being investigated in all test participants.
