In this activity, you'll grow bacteria in four prepared petri dishes. The first petri dish will have a sample swabbed from your unwashed hands. The second petri dish will have a sample swabbed from your hands after washing them with regular soap. The third petri dish will contain another sample from your unwashed hands. The fourth petri dish will contain a sample taken after cleaning your hands with hand sanitizer. What do you think the results will be? Write down your predictions for which samples will show the greatest and least bacteria growth. bacteria: unicellular organisms that sometimes have cell walls but do not have organelles and an organized nucleus

Answers

Answer 1

Answer:

Explanation:

In this study, the swabs taken should represent different amounts of bacteria growth. The samples that were swabbed from unwashed hands should show the greatest bacteria growth. This is because there already existing bacteria have not been killed and have been allowed to reproduce, and since bacteria reproduce at an alarming rate (roughly doubling every 4 minutes) it would pick up momentum easily. Next, would be the swabs of hands washed with soap since soap cleans your hands killing off most of the harmful bacteria thus lowering its rate of reproduction drastically. Lastly, would be the swabs of hands cleaned with hand sanitizer since hand sanitizer is designed to kill 99.9% of germs it comes in contact with therefore eliminating nearly every germ in your hands. This also makes it very unlikely that the swabs managed to pick up any germs.

What is ancient Egyptian advancements in Architecture?

The Egyptian pyramids are the most well-known examples of ancient Egyptian architecture, although other structures like temples, palaces, tombs, and fortifications have also been researched and unearthed. Levied labourers constructed the majority of the buildings using limestone and locally accessible mud brick.

Egyptian architecture, which has been around since 3000 BC, is known for its huge walls covered in carvings of hieroglyphs and pictures, flat roofs, and buildings like the mastaba, obelisk, pylon, and the Pyramids. Homes were constructed using baked bricks or clay.

Aside from the grandeur of their buildings, ancient Egyptian architects were among the first to use materials like stone; this fact had a significant impact on subsequent Greek architecture and is evidently still in use today.

Thus, option A is correct.

After what event did the Anglican Church in America stop communicating with its English counterpart?
a. The Spanish–American War
b. The Revolutionary War
c. The American Civil War
d. Establishment of the settlement of "New Amsterdam"

Answers

Answer:

The correct answer is B. The Revolutionary War.

Explanation:

The Revolutionary War was the war developed between 1775 and 1783 that faced Great Britain with its colonies in America, and that ended with the independence of the latter and the formation of a new nation, the United States of America. The main reasons why this conflict was generated were the lack of civil, political and economic liberties of the settlers, as well as the feeling of national unity in America on the part of the settlers against the British metropolis.

With the end of the war, relations between nations were resumed, which had been cut in 1775 with the start of the war. But, especially, commercial relations were restored, not so cultural, social and religious connections, which had suffered an abrupt cutoff with the start of the war and would not be reestablished until well into the 1800s.

Four Traits of Empowering People:

1. Love – These are people who look at others in a positive light, seeing the inner and outer beauty in all. More than that, they help others see and honor their own beauty and strength. They see problems as opportunities. For example, if they see someone is lacking nutrition, exercise, or sleep in their daily routine, they provide encouragement – in a loving way – to alter things in their lifestyle to make those changes happen.

2. Attitude – They have a driving passion to bring out the best in people, even if it means some sleepless nights. They want to lift and empower others to thrive through finding and exploring their own passion and interests. They help others trust in themselves and their intuition by encouraging mind, body, and soul connections.

3. Action – They realize it’s not always about themselves and don’t just think about how to make things better, they take action. They also model how to infuse passion, values and goals into daily routines. They live through and with purpose.

4. Perception – Others love, respect, and appreciate their work. Do people believe in you, bring out the best of what you have to offer, and make sure you are fulfilling your dreams? Impactful and empowering people cross check their own agenda with the agendas of others, making sure that everyone around them is connected with their own purpose and passion – if not they stop and make a change to improve it. They don’t dwell on it but cycle back to love, attitude, and action.

Intellectual property rights are important to a free enterprise system because they:
A. ensure that all companies benefit equally from new ideas.
B. help governments set prices for essential products.
C. prevent the courts from interfering with private businesses.
D. prevent companies from stealing ideas from innovators.

Answers

Answer:

D.  prevent companies from stealing ideas from innovators.

Explanation:

Ideas/inventions alone are not enough to be successful in business. People also need to have the capital and connections necessary to be able to sell the products that they invented to the market.

Without Intellectual property rights, massive corporations could just take away  game changing ideas/inventions from the smaller innovators and beat their sales in the market simply because they have larger capital. (These massive corporations could spent a lot more money for things such as advertising and mass productions .)

This is why intellectual property rights are important. So new businesses are not discouraged to invent a new/better product and join the existing competition in the market.

Answer:

Prevent companies from stealing ideas from innovators.It allows entrepreneurs to profit from their ideas.

Explanation:

Intellectual property is as vital. It protects the same type of work and the same esteem as property. IP rights are worth securing, both home-wise and overseas. Most free-market advocates will continue to recognize these points rather than falling for myths and misunderstandings.

Unregulated free enterprise refers to business activities by the government but is defined by a set of legal rules such as property rights, contracts, and competitive bidding.The argument for free enterprise is based on the belief that government interference in business and the economy hampers growth.A free enterprise legal system tends to result in capitalism.

Intellectual property (IP) contributes enormously to our national and state economies. Dozens of industries across our economy rely on the adequate enforcement of their patents, trademarks, and copyrights, while consumers use IP to ensure they are purchasing safe, guaranteed products. It thus guards the life and freedom of its owners and provides uniquely important support to free expression and free inquiry.

Which economic power given to the government in the Constitution do antitrust laws best exemplify?

Answers

Answer:

Hope it helps,9please let me be the brianlist :):(

Explanation:

Antitrust and competition law training is one of the proactive measures organizations can take to ensure employees have a basic understanding of the major federal antitrust laws, how they affect business activities, and how to avoid behaviors that can result in costly violations and harm to the organization’s reputation.

Antitrust laws in the US, which include the Sherman Act, the Federal Trade Commission Act and the Clayton Act, are designed to protect competition in the marketplace. Fair competition in business can benefit consumers with lower prices, higher quality, more selection and better customer service. The Federal Trade Commission (FTC) and Department of Justice (DOJ) enforce these antitrust laws and set penalties and fines. In addition to complying with federal antitrust laws, businesses must also comply with state antitrust statutes that are enforced by the states’ attorney general.

As part of an effective compliance program, providing antitrust and competition law training helps organizations manage and minimize the risk of violations, and ensure employees, at all levels, understand their responsibility to recognize antitrust red flags and report their concerns.

Amongst the other English colonies, Penn was the first leader of his colony that established peace with the natives. Then Penn made a peace treaty with the Leni Lenape Indians and bought land from them. He hadn't needed to but did anyway, and it was this act, as well as other kind acts towards the natives that formed peace between them. This also ensured a prosperous beginning for the new settlers of Pennsylvania, as the natives helped them with their crops, learning the way of the land and many other useful things.
