You are a researcher interested in studying Schwann cell development. It is known from prior work that Schwann cells express the protein Sox10. You decide to create a transgenic fish line to label the Schwann cells. Explain how you would create the transgenic embryos. Be as detailed as possible.
Solutions
Expert Solution
* Transgenic embryos are created by genetic manipulation of host species that carry exogenous genetic material or genes from other species in their genome.
* This technique is used to introduce new genes or genes of interest into strains of laboratory to study function and pathology regarding specific gene.
* Fish is the first genetically modified animal to be used for consumption in humans.
* The fish is essentially an Atlantic salmon with single gene complex inserted, a growth hormone regulating gene from chinook salmon with a promoter sequence.
* The aim is to introduce new trait to fish that before does not occur in nature as a species. This process is called trans genesis.
* Genetically modified fish are developed as environmental pollutant sentinels and also used in aquaculture for production of food.
Transgenic fish are used in research centers
* Indicators of aquatic pollutants.
* used in functional genomic studies.
* Development in biomedical use as reactors for important proteins, used in cardiovascular diseases etc.

A researcher was interested in studying the phenomenon known as
social distance, the reluctance of people to associate with members
of different ethnic and racial groups. She designed an experiment
in which students enrolled in a lecture course were asked to choose
a discussion group (all meeting at the same time in the same
building) based only on the ethnic–racial stereotype associated
with the names of the teaching assistant:

You are interested in studying the effects of a drug
that is known to inhibit learning and memory functioning. You have
decided that you will use rats, rather than humans, in your
study.
a. Which neurotransmitter is the drug likely affecting and
why?
b. Which research method would you use to study this and why
would you choose that particular method over another? If this
method were unavailable, describe another method you could use and
why you would choose this...

1. The researcher from the Annenberg School of Communications is
interested in studying the factors that influence how much time
people spend talking on their smartphones. She believes that gender
might be one factor that influences phone conversation time. She
specifically hypothesizes that women and men spend different
amounts of time talking on their phones. The researcher conducts a
new study and obtains data from a random sample of adults from two
groups identified as women and men. She finds...

A researcher is interested in studying the effect that the
amount of fat in the diet and amount of exercise has on the mental
acuity of middle-aged women. The researcher used three different
treatment levels for the diet and two levels for the exercise. The
results of the acuity test for the subjects in the different
treatment levels are shown below.

Scenario: Imagine you are a researcher who is interested in
studying whether sleep deprivation leads to increased reaction
times (i.e., being slower) when driving. You randomly select a
sample of 30 licensed drivers. Fifteen participants are randomly
assigned to get 5 hours of sleep for three consecutive nights. The
other 15 participants are randomly assigned to get 8 hours of sleep
for three consecutive nights. For the purposes of this Assignment,
assume that all participants sleep exactly the required amounts....

A researcher at the Annenberg School of Communication is
interested in studying the use of smartphones among young adults.
She wants to know the average amount of time that college students
in the United States hold a smartphone in their hand each day. The
researcher obtains data for one day from a random sample of 25
college students (who own smartphones). She installs an app that
registers whenever the smartphone is being held and the screen is
on. The sample...

A researcher was interested in the anxiety present in students
just prior to the midterm exam. The research used an anxiety
self-quiz to gage the student's anxiety. The score for 30 students
are: 69,61,84,99.66.86.91.94,54,66,77,48,
70,70,86,98.56,43,70,88,78,53,85, 40,86,79,58,40,89,70. 1.
Construct a frequency table with class, frequency, relative percent
and cumulative percent that has 6 classes to describe the
distribution of the data. 2. Use the frequency table to construct a
histogram. 3. Calculate the numerical descriptive statistics mean,
median, standard deviation, and...
