Topic

Vaccines. Your friend is worried about the many vaccines that his newborn son is scheduled to receive and asks you for advice since you are taking a biology course. Start with an explanation of how vaccines work. Briefly contrast the traditional methods used to create vaccines with more recently used biotechnology techniques. Then list some of the diseases that babies and children in the US are routinely vaccinated against. How have vaccinations impacted the frequency of these diseases over the past 100 years? Why are some people worried about giving their children vaccines? Is there scientific evidence to support these concerns? Conclude with advice to your friend in regard to getting the recommended vaccines based on what you learned from reliable information sources.

You must  find a news article on your chosen microbe published in the last 12 months in a main stream, media-outlet based, mass-distributed news source where the general public (even Grandma or Aunt Sally) gets their daily news. This news article will be your main reference.  You must read for understanding, then tell us about the news report in your discussion.  You must write a review of the news article contents, discuss what type of microorganism it is, and if the organism is in nature or is used in industry or research or causes disease. If it causes disease you must discuss transmission, increasing incidence, factors contributing to the spread of the organism, lab culturing, etc

E.  You may use government-based or other scholarly references only as secondary information, to explain details missing from your news article above, such as, what kind of organism it is, the gram reaction, how the organism affects us, or follow -up information not known at the time of the news release but has been provided since that time .

F.  Your  discussion should be well-written, in your own words, paraphrasing from only credible academic sources. You may not directly quote from your sources; minimum elaboration on the topic of a minimum of 300 words and maximum of 400 words.

G.  You must also cite your credible academic reference sources with parenthetical in text citations (in parentheses), and provide full end ref information in APA 7th Edition format.

Cultural Geography

February 15, 2021 Leave a comment Natural science, Not applicable

This time I want you to do follow up post regarding #190616965.

Your follow-up should consist of two parts, and be about 150-250 words total for both parts (or more, if you’d like). You may choose to respond to the same classmate or to two different classmates (one for each part).
1. First, comment on a classmate’s meme/macro/gif. The comment can take any form; you can draw connections to something from your daily life or another meme, highlight certain elements and explain why you think they’re notable, comment on its cultural specificity, etc. However, it should be substantive, i.e., do not simply state that it is “funny”, “interesting”, or things of the like.
2. Second, answer/respond to a classmate’s question. Again, this should be substantive; do not simply state it is “an interesting question”, etc.

I attached the screenshot of post which I want you to reply to. I thought this classmate’s post is relevant to your post #190616965.

Also I have uploaded the last week discussion pdf which was about different readings, but you can see how classmate respond to other classmate’s posts. As you can see, it can start with “Hi, classmate’s name”.

Restoration Phamplet

February 14, 2021 Leave a comment APA (edition "APA 6"), Natural science

Select a scenario from the list below:
1. There is a species of fish (with low numbers) that is having trouble traveling up and down the river because of a dam.
2. Chose an area that is economically depressed but has a lot of species diversity, you need to protect the species while providing jobs for locals.
3. An animal is being poached for its horn which is believed in some cultures to cure many diseases, it is not critically endangered.
4. The demand for farming is increasing, which is destroying native forests and affecting their biodiversity.
5. An animal is starting to become isolated because it is afraid to cross roads created by deforestation.
6. Local birds typically migrate over the winter, but people are feeding them and thermal pollution at a local stream is keeping the water warmer the birds are not migrating, resulting in water pollution.
7. A drought has been going on for a period of time; the water needed for homes, businesses, and farms has decreased lake and river levels impacting the amount available for local flora and fauna.
8. Species are being found dead on local beaches due to plastic.

Create a pamphlet addressing the following:
1. What is the issue and why it would work
2. Describe the restoration method you selected and why it would be best (with at least 2 examples of how it has worked in similar situations from peer reviewed sources)
3. Time frame to complete the plan (include short and long term objectives)
4. What is the end goal of the restoration project

Responses

My assignment is to respond to at least two classmates by defending which device made the largest difference in the history of science and technology. So respond to their discussions in 4 to 5 sentences.

This was the discussion post:
Initial prompt: Choose an electrical or magnetic device (resistor, capacitor, diode, fuse, transformer, motor, generator, ammeter, voltmeter, etc). In your 300-400 word initial post, explain the purpose of the device and how its invention changed circuitry, power transmission, or power generation.

These were my classmates responses:
1.
A diode is an electric component that is specialized to act as a one-way switch (Braza, n.d.). A diode is responsible for conducting electric current in only one direction, while blocking current from the opposite direction. In simple words, a diode acts as a one-way switch for current in a built-in electric field. A diode has two sides, a positive side and a negative side. The polarity in a diode is determined by an anode (positive lead) and a cathode (negative lead) (Fluke Association, 2021). While most diodes only allow current to flow when positive voltage is applied to an anode, there are very few that only allow current to flow when a cathode is charged.

A diode may play two different types of roles in a circuit. A diode is forward-biased when it allows current flow. On the other hand, a diode is reverse-biased when it acts as an insulator and does not permit any current to flow. Diodes are also known as rectifiers due to the changes they cause in alternating current (ac) into pulsating direct current (dc) (Fluke Association, 2021). There are different types of ratings diodes go by, it is all based on their type, current capacity, and voltage.

Each diode is assigned a different rating. If the rating is exceeded the diode may fail and will either allow current to flow in both directions, or prevent the current from flowing in either direction (Fluke Association, 2021).

Diodes are used in LEDs. LEDs only glow when there is positive voltage present (James & Granath, 2020). The diodes are used to only allow positive voltage through.

A generator is a dynamo or similar machine for converting mechanical energy used for backup emergency power.  It is essentially an electric motor working in reverse conversion with many similarities to engines (i.e., automobiles, aircraft, ships, and trains) and provide nearly all of the power for electric power grids.

In 1831, Michael Faraday, a British scientist, discovered electromagnetic induction, which is when a conductor moves in a magnetic field, electrical changes could be created and directed to create a flow of current. By 1832, Faraday was able to apply electricity to a functioning electrical motor which paved the way for other inventors to hone and perfect it as well. The invention of a generator changed circuitry by powering the electrical motor and the importance of the technology.

An electric generator is a device that changes kinetic and electrical energy through electromagnetic induction. 

In electricity generation, a generator doesn’t create electricity, however, it is a device that converts mechanical energy into electrical power for use in an external circuit.

The mechanical power for an electric generator is usually obtained from a rotating shaft which is equal to the shaft torque multiplied by the rotational, or angular, velocity.  Generators are available in many different fueling options such as, diesel, natural gas, and portable/ mobile types. (Worldwide power products, 2021) 

They also provide electrical power and electrical generators housed in power plants making power rapidly available. A generators output of electrical power is measured by kilowatts and in a circuit analysis, you often use it to stand as an idealized version of another component, such as a battery, transistor, etc.

A portable generator is a diesel or gas fueled device that engine turns an alternator that creates usable electricity up to a certain level of wattage that can plug electrical appliances or tools directly into the generator outlets. All of these machines convert mechanical energy to electricity for transmission and distribution over power lines to domestic, industry, and commercial consumers.
