The hobby of fish keeping is much more difficult than it seems. It is also directly dependant on science. The bacterial cycle is one aspect related to science. As is how different filters work. Water conditions such as temperature, ph, and salinity play a big role in successful fish keeping as well. Science and Fish keeping go hand in hand.
When a tank is first started fish waste and excess food begins to decompose at the bottom. One type of bacteria breaks it down to ammonia, which is highly poisonous to fish. Then a second type of bacteria breaks down the ammonia to nitrites, nitrites are also moderately poisonous to fish in small amounts. Lastly a third type of bacteria converts nitrites to nitrates which are not harmful to fish but build up to toxic amounts generally within a few months. That is why 20% water changes every two weeks is essential to healthy fish keeping. It generally takes a tank 21 days to cycle. During those 21 days there are 3 days where the ammonia spikes to a large amount and 2 days later on when nitrites spike generally.
There are 2 types of filtration for fish tanks biological and mechanical. Biological is what I spoke about in the previous paragraph. Those bacteria grow best on objects besides gravel. That is why having plastic plants and other décor in the tank doesn’t just make the tank look nice but also give the bacteria a better place to grow. Mechanical filtration aids in biological filtration in two ways, the water is filtered through a medium that helps dissolve the ammonia and nitrites into smaller pieces easier for the bacteria to convert, and filter out bigger objects from the water such as excess food. Generally the filter media is activated carbon within a floss cartridge.
The ph value in a tank doesn’t generally matter for basic to medium aquarium hobbyist. As long as it is between 6.5 and 7.2, ph ranges from acidic to base water. Some fish however like higher more acidic ph values, where as some fish are very stressed in acidic water and are more susceptible to disease and death. Temperature is very important to maintain to a certain extent. Most tropical and salt-water fish enjoy temperatures from 68°F-78°F. It is essential to have a heater in your tank to maintain the temperature. Salinity is important to monitor and control in salt water tanks.
Conclusively and strongly stressed to the naive freshwater fisherman, freshwater fishing can shockingly differ from saltwater fishing. Successful freshwater fishing is allowed by simpler and more practical means, including a wider range of lure selections, limp and simple line, and the lightest of gear. It has minimal demands on fishermen and equipment. Saltwater fishing, on the other hand, surely does not.
...ank you have to make sure that the right temperature stays in the tank because if the water gets to hot they wont really have a place to go too, so they could end up over heating and could die. It is also important to have the right type of food for them as well. They like to eat worms, squid, and sometimes other fish.
It has been said that Legalism takes after Daoism, borrowing some of its well-known ideas such as non-action or the usefulness of being empty. Though Legalism is typically grouped with the other early Chinese philosophers, it is actually quite a different system. Han Feizi’s Basic Writings, an exemplary text of Legalism, is aimed at how to successfully run an empire, and caters to one person in particular: the ruler. On the other hand, writings like the Dao de Jing are aimed more towards the individual and are personable. Still, it’s interesting to note that both texts talk about what it takes to be a good leader. In examining relations between Laozi’s Dao De Jing and Hand Feizi’s Basic Writings, one can extract both similarities and differences between Legalism and Daoism when it comes to how a leader should govern. Daoism and Legalism are similar in the fact that they both believe the leader should practice non-action and emptiness, believe that there should be a natural
Schools are meant to give our children a healthy and nurturing environment, and yet so much of the lunches in schools are fattening; does this stop schools from achieving the aforementioned goal? Childhood obesity in the United Sates continues to be a growing problem despite so any new programs to help combat it, and new research is showing how schools may be playing a large role in childhood obesity. School lunches are showing to be the problem, they encourage poor nutrition in our nation’s students, and simple reform is proving to not be enough to stop the rise in obesity rates.
• Understand the movement of fish. Since small water bodies have limited oxygen supply, fish tend to stay shallower. On the contrary, fish in larger lakes have adequate oxygen supply; hence, fish tend to stay where there is food. The fish may also stay deeper because the temperature of the deep water is slightly higher.
The lack of health standards for lunches and other foods in schools are a leading cause of obesity in children. According to studies, children who eat school lunches consume forty more calories each day compared to those who bring their own lunches (Schanzenbach 703). Elizabeth Jackson, a medical doctor at the University of Michigan Health System, reported that children who eat school lunches are over two times more likely to eat fattier foods and more sugary drinks (“Children”). In the past decades, the government has attempted to develop effective lunch programs that limit the intake of unhealthy foods that children eat. The 1995 policy, “School Meals Initiative for Healthy Children,” required school lunches to meet one-third of the recommended number of calories, protein, and certain vitamins and minerals (Schanzenbach 686). Although this policy has been put into place, the government has not enforced it well enough. According to a recent study, only six percent of U.S. schoo...
With the implementation of the “Healthy Kids Hunger-Free Act” schools are not serving as many lunches and participation is decreasing. According to the Government Accountability Office (GOA), “Nationwide, student participation declined by 1.2 million students(or 3.7 percent) from school year 2010-2011 through school year 2012-2013, after having increased steadily for many years”(sec. 1). The school lunches became more distasteful and bland; the combinations of foods did not make sense, and the portion sizes decreased significantly. In order to support the cafeteria
Turkle throughout her papers has a claim and reasons that support her claims, but her backing and warrants are non-existent, which leads to the emotional rants that make up the article. The audience in general isn’t moved to think her way when all they get from her paper is the rant with nothing to strengthen her points. She also doesn’t give the other side of the argument a chance and continues to bash it without letting it have its fair chance. One of the many examples of her rant structured arguments is “Texting and e-mail and posting let us present the self we want to be… not too little- just right.” (Turkle). This argument wants people to see how much we can change from who we really are in real life to how we perceive ourselves over the internet. It doesn’t have a backing or any other supporting methods just a claim and a lot of emotion that she hopes will convince you of her main argument. With this Turkle hopes that the audience will be swayed without any effort put into the argument. Instead of being moved to think the way Turkle does, the audience members question the validity of any of her claims due to the fact they are emotionally heavy and do not provide any substance to truly back up her main point in the
The definition of Interpersonal skills are the life skills, we use every day to communicate and interact with other people, both individually and in groups. People who have worked on developing strong interpersonal skills are usually more successful in both their professional and personal lives.
The biggest social institution that made an impact on my life was my education. For my whole

She believes that people’s communication skills have been deeply affected by the overuse of online resources. Turkle began by listing the growing importance of technology for lonely individuals who depend on devices to feel compassion by stating,“we expect more from technology and less from one another and seem increasingly drawn to technologies that provide the illusion of companionship without the demands of relationship” (Turkle). All humans are aware of the abundant amounts of time and effort that go into maintaining a healthy relationship. Turkle’s examples revealed that people have started to become more attached to cellular communication than personal contact, because of the easier access to talk to “anyone anywhere”, with the ability to “edit your words at any time” (Turkle). Turkle tackled her stance with the opinion that the more time a person spends on the internet to feel less lonely, the more lonely they actually

Freshwater fish and saltwater fish are very similar in a lot of ways, but also have differences between them so you can tell them apart. Marine water (saltwater) equals over 96 percent of the water on Earth and over 70 percent of Earth’s total surface. Freshwater is less than four percent of Earth’s total water and is about one percent of Earth’s surface (Freshwater Fish). Interestingly a few species of fish can live in either freshwater or saltwater, but for the majority, they must live in a specific environment. All species of fish used to live in a saltwater environment until certain geological events (earthquakes, volcanic activity, etc.) occurred, creating conditions that isolated groups of fish. The new habitats, included freshwater, and new food sources caused fish to either adapt, or to die (Lohrey).
The day has come in my household where poles are being taken for the next family member. After careful consideration, my family and I have narrowed down the new family member to be either a dog or a fish. At first glance, I thought these two animals to be on completely opposite ends of the spectrum of pets, and after careful consideration, dogs and fish have a good bit of similarities and differences. Both animals need to be fed daily and kept in a clean environment. However, these differences will be the determining factors as to which new family member wins. The differences in dogs and fish are found within their habitat, interaction, and levels of activity.
