Come up with five ethical guidelines for research. Write statements that reflect your own views of what is right and wrong. If you really love animals, an example of one guideline might be “No animals may be used in research of any kind.” However, when coming up with these guidelines, be thoughtful about what they really mean. Think of the information you read about earlier. Try to phrase your guidelines in a way that would allow research that you think would be beneficial to still be done. You may find that certain circumstances may cause you to rethink your own ethics!
Ethical Guidelines for the Use of Animals in Research
Respect for animals' dignity.
Responsibility for considering options (Replace)
The principle of proportionality: responsibility for considering and balancing suffering and benefit.
Responsibility for considering reducing the number of animals (Reduce)

PLEASE HELP. I REALLY NEED THIS!!!!
Answer:
In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!
To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."

What are some ways you can reduce the number of fishnets in the ocean?
Answer:
August 11, 2014 — Six years ago, the Norwegian coast guard filmed a Scottish fishing vessel riding gray swells, dumping 5 metric tons of dead fish back into the North Sea. Over the European Union catch quota, and so unable to keep all the fish they’d caught, the fishermen had to ditch some. To the Norwegians, who aren’t part of the EU and hold a strict discards ban, the waste was shocking.
When this news reached Dan Watson, a young British designer, it became the inspiration for SafetyNet, an ocean fishing net that allows certain fish to escape via lighted rings, offering more catch selectivity. The Scottish fishermen’s predicament, he believed, was driven by their lack of control. “There can be no villains, there can be no victims, there are just problems,” Watson says. “I started this project because I wanted to go some way towards solving that problem.”
Bycatch can result in overfishing, reduces the population of species that might already be endangered and, on the largest scale, interrupts food chains and damages whole ecosystems.
Watson joins a growing number of innovators designing more selective fishing gear to reduce bycatch — the unwanted fish, dolphins, whales and birds that get scooped up by longlines, gillnets and trawlers each year and then discarded. Globally, the amount of marine life that is wasted or unmanaged — which makes it potentially unsustainable — forms about 40 percent of the catch. “The way we catch now is to catch everything, decide what we want to keep, and discard the rest,” says Martin Hall, head of the bycatch program at the Inter-American Tropical Tuna Commission, which regulates tuna fishing in the eastern Pacific Ocean. Bycatch can result in overfishing, reduces the population of species that might already be endangered and, on the largest scale, interrupts food chains and damages whole ecosystems. It also amounts to an enormous waste of valuable fish protein.

To designers building better nets and lines, bycatch isn’t viewed as an inevitability, but as something we can phase out, piece by piece. It’s also seen as a battle that needs to be fought alongside fishermen, not against them.
Rethink the Game
Speaking from his trawler, the 45-foot Proud Mary, off the coast of Massachusetts, one such fisherman, Christopher Brown, says that over the years, fishermen have had to “rethink the game.” Brown operates a fishery that’s almost completely free of discards; is the board president of the Seafood Harvesters of America, an organization representing stewardship-minded fishermen; and has designed a squid net that reduces bycatch. The net contains an escape route at its base that exploits the bottom-dwelling behavior of unwanted flounder, encouraging them to flee the net through this gap. “We need to look at things entirely differently than we have in the last 30 years,” Brown says — and new gear is part of that equation. “It’s a matter of enlightened self-interest.”

How does air pollution deplete ozone layer?
The ozone depletion process begins when CFCs (chlorofluorocarbons) and other ozone-depleting substances (ODS) are emitted into the atmosphere. CFC molecules are extremely stable, and they do not dissolve in rain. After a period of several years, ODS molecules reach the stratosphere, about 10 kilometers above the Earth’s surface. CFCs were used by industry as refrigerants, degreasing solvents, and propellants.
Answer:
Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity
And object is 20 cm from the lens. The image from 6.66667 cm from the length. What is the focal length of the lens? Use the thin lens equation
Answer:
5
Explanation:
The object distance Is 20 I'm
The image distance is 6.666
Therefore the focal length can be calculated as follows
1/f = 1/20 + 1/6.66
= 6.66+20/133.2
= 26.66/133.2
1/f= 26.66/133.2
f = 133.2/26.66
= 4.99
= 5
Hence the focal length is 5

Compare the number of mitochondria in the different types of cells.
Answer:
High amounts of mitochondria are found in skeletal muscle cells, as well as liver cells. On the other hand, skin cells have a small amount of mitochondria.
How can you explain the difference in number of mitochondria in these types of cells?
Answer:
Organs which need alot of energy to function properly have a greater number of mitochondria
Explanation:
Mitochondria are sites for respiratory enzymes which yield energy for the cells thus skeletal muscles which need alot of energy have more mitochondria than liver and liver due to doing more activities than skin has more mitochondria than the skin.
Answer:
Skeletal muscle cells have a very high amount of mitochondria as well as liver cells because they need high amounts of energy to carry out their functions, whereas skin cells don't need high amounts of energy to function.

Rain washing oily runoff from a road into a river that runs alongside the road is an example of point source pollution or nonpoint source pollution?
Help pls.
Answer:
This would be an example of nonpoint source pollution.
Explanation:
The source of point source pollution is typically factories and powerplants, leading to more air and water transferred pollutants and becoming easier to track. Nonpoint source pollution is the opposite of point-source pollution, with pollutants being released in a wide area. Since the rainwater would be washing the oils and particles into the water, it would be considered runoff. Runoff is one of the leading causes of point source pollution. I hope this helps. ^_^

Why is it difficult to fossilize large animals?
Answer:
The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.
