“The Cell, Lokiarcharum, and the Chemicals of Life”

This week is all about the some of the smallest parts of life: atoms, molecules, and cells. For your primary post, please respond to one of the following two topics and address all questions. Also, reply to at least one fellow student on any topic.

Topic 1

: Introduction to the Cell. Watch the Khan Academy video “Introduction to the cell” (1)* and then address the following issues.

  • (a) In the video, the narrator says that we might think that since cells are so small, that they must be simple, but “nothing could be further from the truth.” What did he mean by that?
  • (b) Describe features that are only found in eukaryotic (but not prokaryotic) cells.
  • (c) Did anything in this video surprise you, or was it mainly a recap of material you already knew?

Topic 2 [article]: Lokiarchaeum. Read about Lokiarcheum in the article by Yong (2)* and/or the article by Zimmer (3)*. Both articles describe recently discovered evidence about a previously unknown organism. Then, address the following questions:

  • (a) Lokiarchaeum may be a “transitional form” between archaea and eukarya. What evidence suggests this?
  • (b) Describe one way that this relates to this week’s lesson.

Topic 3

: Chemicals of Life Video. (added on 1/8/2018)  Watch Dr. Cox’s video on the “Chemicals of Life” (4)* in the “Instructor Insights” area of Week 2. Then, describe three things you learned from this video.

Note:  To get credit for this topic, your post must be based on the video. Answers based on other materials will receive a grade of zero.

Biology Assignment 1

Biology Assignment 

You are a doctor in a hospital, and a patient is experiencing trouble with her skin repairing itself from a cut. The patient is also expecting a child, but the cells in the reproduction development are experiencing malfunction in cell division.

  • Describe the stages of each type      of cell reproduction process from a normal patient whose body cells can      repair themselves and normal cell division during the reproductive      development of the unborn baby.
  • Explain the disadvantages and      advantages of each type of cell division.
  • Discuss how the patient      experiencing problems with the cells repairing from the cut and the      child’s reproduction development malfunctions can alter haploid and      diploid cell development.

Community Action Plan Outline

 

Opioid Crisis in Winston-Salem, NC

Professor Feedback:

 

Mara: There is no clear identification of option 2 in the title. Your outline gives a good idea of what you will need to cover in the final project and is detailed enough (more than the assigned 2 pages). It shows the logic of your analysis of opioid abuse in Winston-Salem. You cited several appropriate sources. It is clearly organized in Symptoms, Diagnosis, Cure, and Prevention sections, and is written correctly as an outline. APA is ok.

 

I. Introduction

A. Opioid crisis entails extensive opioid overuse from medical and non-medical prescriptions

B. This issue started in the late 1990s, following the increased prescription of opioids for the management of pain. It led to an increase in the usage of opioids, both prescription and non-prescription, throughout the U.S in subsequent years (Guy Jr, Zhang, Bohm, Losby, Lewis, Young & Dowell, 2017).

C. Winston-Salem, North Carolina, is not excluded from this opioid crisis.

a. Winston-Salem is a city in Forsyth County. According to Briker (2008), the town emerged following the merger of Winston and Salem towns in 1913.

D. Thesis: Opioid crisis is a significant public health issue in Winston-Salem, calling for action.

II. Body paragraphs

A. Symptoms

a. The issue affects mostly non-Hispanic whites aged 18 and above.

i. People aged 26 years and older are the most frequent users of prescription opioids, while the age group with the highest non-medical opioids use is young adults between the ages of 18 and 25 (Green, 2017).

b. The signs of symptoms of this crisis among individuals include dependence on opioids, prioritization of acquisition and use of opioids over other activities such as school and work, and weight loss. Other symptoms include lack of hygiene, drowsiness, isolation from family and friends, engaging in risky behaviors, being nervous, losing interest in activities previously enjoyed, and experiencing financial hardships (Green, 2017).

c. In the community, the symptoms indicate that opioid use has become a crisis include increased health care and criminal justice costs (Birnbaum, White, Schiller, Waldman, Cleveland & Roland, 2011).

B. Diagnosis

a. One of the primary roots of the opioid crisis is the initiation of opioids for pain management (Green, 2017).

i. Increased number of people affected by chronic pain pushed the use of painkilling opioids.

b. Continued use of opioids beyond doctor prescriptions to minimize pain or induce eutrophic feelings (Green, 2017).

c. Opioids are inexpensive to acquire.

i. When compared to alternative intervention for pain management such as physical therapy, opioids are relatively inexpensive (Green, 2017).

d. Other communities affected by this opioid crisis include Lockbourne in Pickaway County, Ohio, and Kermit in Mingo County in West Virginia.

e. Measures to address this issue by these communities:

i. Providing education and distributing naloxone (Palombi, Olivarez, Bennett & Hawthorne, 2019)

ii. Educating members of the community on safe usage, storing, and discarding of prescription medication

iii. Providing support for community members in the recovery process (Palombi et al., 2019)

C. Cure

a. Pharmacological treatment

i. Medications too address the issue includes opioid agonists such as methadone, acetate, and levomethadyl, opioid antagonists such as naloxone and naltrexone, and non-opioid medication including clonidine and lofexidine (Veilleux, Colvin, Anderson, York & Heinz, 2010).

b. Psychosocial treatment

i. Biofeedback, cognitive behavioral therapy, and psychodynamic therapies improve relapses and treatment retention (Veilleux et al., 2010).

c. Precision Addiction Management has been suggested as an approach to the effectively compact opioid crisis (Blum, Gondré-Lewis, Baron, Thanos, Braverman, Neary, … & Badgaiyan, 2018).

d. Increasing access to treatment and recovery sustenance would enable people with this problem to seek treatment.

D. Prevention

a. Prescription monitoring programs (Hahn, 2011)

b. Ending supply of unfitting prescriptions and illegal opioids

c. Enhancing maternal and prenatal care for females struggling with substance misuse (Hahn, 2011)

d. Supporting the youths through targeted initiatives to lessen youth misuses of opioids

e. Enhance awareness on the risks of opioids use and the costs of opioid misuse on individuals and the community (Hahn, 2011).

III. Conclusion

A. The opioid crisis is a huge public health issue, and thus, addressing this problem is a priority for communities.

Maths Question

  1. Nitrates are groundwater contaminants derived from fertilizer, septic tank seepage and other sewage, nitrate poisoning is particularly hazardous to infants under the age of 6 months. The Maximum Contaminant Level (MCL) is the highest level of a contaminant the government allows in drinking water. For nitrates, the MCL is 10 mg/L. The health department wants to know what proportion of wells in Madison County that have nitrate levels above the LCL. A worker has been assigned to take a simple random sample of wells in the county, measure the nitrate levels, and assess compliance. What size sample should the health department obtain if the estimate is desired to be within 2 percent with 95% confidence if :

A. There is no prior information available?

B. A study conducted two years ago showed that approximately 7% of the wells in Madison County had nitrate levels exceeding the MCL?
