Hooked On a Myth Re “Hooked on a Myth,” Commentary, October 8: Victoria Braithwaite argues that fish have feelings. I agree. Just because fish don’t show any emotion in a way we can see doesn’t mean that they don’t feel pain. People think that because they don’t how emotion we can treat them any way we want Studies show that fish have the same two types of nociceptors that we do, allowing them to detect pain. For example, Braithwaite stimulated the nociceptors by injecting dilute vinegar or bee venom under the skin of the trout.
However, Lionfish can have negative effects on the overall reef habitat as they can eliminate organisms which serve important ecological roles such as herbivorous fish which keep algae in-check on the reefs. Lionfish usually prefer living in still waters protected from any current, in quieter and darker parts of the reef; they are also known to exist in bays, estuaries and harbors. A female lionfish will release between 4,000 and 30,000 eggs during mating to be fertilized by the male’s sperm. This invasive species is growing and spreading rapidly through the Americas. It is uncertain how the lionfish arrived.
The Megladon fish has disruptive coloration, with its spots and stripes it is able to confuse their predators. The Megladon is usually all different colors. The coloration also gives off the warning of being poisonous or that they taste bad. The colored pigments in the fish are found in cells in the skin called chromatophores. The chromatophores allow the fish to rapidly change color by contracting and expanding the pigment in the chromatophores.
Royte’s excerpt makes many views of the effects of tap water and the different types of problems associated with drinking it. In many areas, they say it is okay to drink the tap water but there are a few instances where the water needs to be filtered. She explains the different types of bacteria’s in tap water around the United States but she does tell how the bottled water companies do not answer to the public and how they are being untruthful about their purification of water. Although she believes they are untruthful, she provides little evidence of that. She is being quite vague about her conclusion that water bottles are not the best source of water.
Milk also goes through a process called pasteurization, its intentions are to kill the bad bacteria, but it also strips away enzymes and nutrients that help digest the milk. Thus, the product is considered as empty calories and has no nutritional value (Cleary; DelAmor). Furthermore, milk contains lactose, a type of sugar. Our bodies are not able to digest this kind of sugar, as a result, we produce mucous as a reaction towards the milk. Producing too much mucous causes clogging in your digestive and respiratory tract as well as inflammation (Cleary; DelAmor).
Background Information: * Goldfish are exothermic, meaning their body temperature depends on the water surrounding them. As the water cools/heats the first things to be affected are their digestion, respiration, and immune response. When a gold fish is exposed to extreme cold water, their body starts to shut down their non-vital organs first. They slow down their breathing because they don’t as much oxygen to bring to their working organs. As the water gets heated up, goldfish tend to become more active, and this is the time breeding is most correlated with.
Farm raised fish versus wild caught Cul 110 exam #3 Alexis Halstead There have been many different long standing arguments about the differences between farms raised fish and wild caught fish. There are good arguments against which is better than the other. Although these farming practices have their difference, eating fish has great health benefits and that should also be taken into consideration when deciding which product you will be purchasing. Fish are widely advertised for there health benefits, but there are many different controversies surrounding how they caught and able to be produced in mass quantities. Eating about two servings of fish per week provides healthy amounts omega-3 fatty acids that can help to lower cardiovascular disease.
Drinking water from the tap tastes different, and its not a very safe thing to do I believe. The chemicals that are used to filter the tap water, such as, chlorine, lead and giardia, are toxic and it’s very dangerous for humans. The process of filtering the water strips out all the natural minerals that are found in the water, and our body needs it. While the bottled water is all natural resources, which means the natural minerals are still there. Also it feels like drinking water that its fresh and tasty.
Tomatoes, carrots, and red bell peppers are also good to stay hydrated. The most important thing you can do is to drink plenty of water, especially on really hot days or days when you are exerting yourself. The common complaint about drinking water is that it doesn’t taste good, if you find yourself with this issue there are plenty of ways to flavor water so it is more appealing. On average a person should drink two to three liters of water a day. An amazing statistic I found is “breathing, going to the bathroom and sweating results in about 2.5 liters of water loss a day.” (Squiddo 2010) Squiddo also states that “around 20 percent of water intake comes from food consumption, so drinking at least two liters of water each day, along with a healthy diet, should replenish your
• Water flushes toxins out of vital organs, carries nutrients to cells and provides a moist environment for ear, nose and throat tissues. • Every day you lose water through your breath, perspiration, and elimination of waste products. • Even mild dehydration can drain your energy and make you tired. • For proper body function, you must replenish its water supply by consuming beverages and foods that contain water. 3 Water: How Much Should You Drink on a Daily Basis?
