Thinking And Doing Ethics

PLEASE make sure this writing assignment is original and has excellent grammar skills.

For this module, you are required to complete a Written Case Analysis (200 words) Times New Roman, 12point font, and MLA. Please read Thinking Critically About Ethical Issues, Case 11, p. 120.Please make sure you Identify the moral issue(s) and the parties involved; identify what virtues are at stake or which relationships of care are at stake.

Case 11.   In studying the subculture of a particular group, a sociologist  must be accepted by the people and gain their trust.  One such researcher is studying the people in an urban slum.  She learns through their confidence that certain members of the community are involved in a car-theft ring.  She does not report them to the police

OSMOSIS And DIALYSIS Lab Essay

The format is based on the format used in scientific journal articles where papers have an

introduction, materials and methods, results and discussion. It should be written in 12-point

font (Arial, Helvetica or Calibri), double-spaced and formatted using the APA style for in text

citations and references cited.

• Scientific papers are written in the third person.

o Avoid the use of first person: I, us, we, etc.

• Avoid direct quotes; rather paraphrase

o Inclusion of direct quotes will result in a point deduction.

• Include page numbers on all pages except the title page. The Introduction begins

with page 2. The References Cited page has a page number on it by is on its

own page.

• Include a running head (described below).

Cell Structure And Function ANSWER KEY

This contains 100% correct material for UMUC Biology 103 LAB03. However, this is an Answer Key, which means, you should put it in your own words. Here is a sample for the Pre lab questions answered:

 

 

Pre-Lab Questions

1. Identify the major similarities and differences between prokaryotic and eukaryotic cells. (2 pts)

Prokaryotes tend to be less complex than eukaryotic cells, with fewer organelles and (generally) fewer requirements for survival. Eukaryotes have a nucleus, while prokaryotes do not. Both eukaryotes and prokaryotes have DNA, a cell membrane, and cytoplasm.

 

2. Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic cell? (2 pts)

DNA is housed in the nucleus in eukaryotic cells. Prokaryotic cells do not have a nucleus, and thus DNA exists freely in the cytoplasm.

 

3. Identify….

Microbiology Lab Report- Gram Staining, Simple Staining, Negative Staining

1. Do a search online 1-2 antibiotics that affect Gram-positive bacteria and list them. On what part of the cell do the antibiotics usually work? List one or two antibiotics that affect Gram-negative bacteria? On what part of the cell do the antibiotics usually work? (Be sure to cite your sources in your answer.) (5 points)

2. Why do you think it is important to identify a bacterial disease in a patient before prescribing any antibiotic treatments? (Be specific.) (5 points)

3.   What are some of the limitations of simple staining? (5 points)

4.   Give an example of a situation in a lab or medical setting in which simple staining would be utilized. (5 points)

5.   So far in this lab, you have used one type of simple….

Mendelian Genetics Lab

Background

The laws of segregation, independent assortment, and dominance, discovered in the mid 19th century by Gregor Mendel, form the basis of all genetics. The ability to predict the results of crossing experiments and explain any variance between expected and observed results is still a vital part of our understanding of heredity. The relationship between the genotype and the phenotype of an organism is now understood with better clarity than it was in the early part of the 20th century. Today our ability to determine gene sequences in individual organisms and populations of organisms has allowed us to deepen our understanding of heredity. In this lab assignment you will experiment with monohybrid crosses and explore the role of chance in genetics.

 

Taxonomy ANSWER KEY

This contains 100% correct material for UMUC Biology 103 LAB06. However, this is an Answer Key, which means, you should put it in your own words. Here is a sample for the Pre lab questions answered:

 

 

Pre-Lab Questions

 

1. Use the following classifications to determine which organism is least related out of the three. Explain your rationale. (1 pts)

 

 

The Eastern Newt is the least related organism out of the three. While all three are classified into the same domain, kingdom, phylum and class the Eastern Newt is in a different order than the American Green Tree Frog and the European Fire-Bellied Toad.

 

2. How has DNA sequencing affected the science of classifying organisms? (1 pts)

DNA sequencing has allowed for….

Introduction To Science Answer Key

This contains 100% correct material for UMUC Biology 103 LAB01. However, this is an Answer Key, which means, you should put it in your own words. Here is a sample for the questions answered:

 

 

Exercise 1: Data Interpretation  (2 pts each)

1. What patterns do you observe based on the information in Table 4?

No fish are present when the dissolved oxygen is zero. When there is more dissolved oxygen in the water, more fish are present. However, the number of fish tends to drop or level off when the dissolved oxygen is higher than 12 ppm.

 

2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.

Possible Hypotheses:

….
