Compare and contrast correlational and experimental research by designing two types of studies that aim to answer the same quest

ion:
“How does sugar affect the attention of small children?”

1. Identify the Independent Variable for the question above (2pts):
2. Identify the Dependent Variable for the question above (2pts):
3. Using the question above, how would you design a correlational study (there are different types - refer to observational research in your notes) to obtain data that helps respond to the given question? Give specific detail regarding how you organize the study and collect the data. Keep in mind the characteristics of a correlational study and how it differs from experimental research. (5pts)

Answer:

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between variables. The correlation coefficient is usually represented by the letter r.

alisha [4.7K]

Answer: D- Parasitism

Explanation: Parasitism is an intimate and long-term impact or interaction that a couple of organisms living in the same habitat have on themselves between two distinct living beings, where one organism lives on another living being which gives it food, eater and shelter at the expense of the other organism.

The organism that lives in the host organism causes it some damage and gives no benefits at all. Also, the parasites are usually insignificant in size when compared to the organisms they live and feed on so they are able to survive in a large category of environmental situations. In this case, the dwarf mistletoes are the parasites while the trees are the hosts.

Three facts about DNA structure replication
statuscvo [17]
Hey friend!
Let's figure this out!

DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule. DNA replication is self-complementary, and it does not need a third party. The two strands of a DNA act as parents and work as a template to synthesize the two daughters of DNA. According to an estimate, there are nearly 3 billion DNA bases in our genome, and during DNA replication they all replicate. Mutation can cause changes in DNA bases only, but it can be one or even more than one basis.<span>

During high-intensity exercise, from where do muscles primarily get their energy?
ad-work [718]
During high-intensity exercise, muscles primarily get their energy from the  carbohydrates we intake. These biomolecules are what the body uses to store and produce energy for each activity we do. These substances are very important to be part of our diet.

What is the mRNA sequence for the template strand DNA sequence?3' TACAAACTAGAA 5' *
True [87]

Answer:

5' AUGUUUGAUCUU 3'

Explanation:

The nucleotide bases for mRNA are Adenine, Guanine, Cytosine, and Uracil. Uracil replaces Thymine (it's DNA counterpart). From this, you can eliminate options C and D.

Then it is just matching pairs: Adenine = Uracil , Cytosine = Guanine.
