Parents should not be informed that their teen is requesting abortion essays

Parents should not be informed that their teen is requesting abortion essays I feel that parents should not be informed that their teen is requesting an abortion because it will lead to more teenagers giving birth to unwanted children, unsafe and illegal abortions, infant abandonment, and even worse, infant murder. Within the past few years, infant killing by teenagers is on the rise. In one case, a teen hid her pregnancy and nine months later gave birth to the baby boy in the family basement. Afterward she placed the infant in a garbage bag, leaving him for dead. Admittingly, most teens will not resort to such drastic measures. However, the teen admitted that she was afraid to tell her mother because she claimed her mother told her after her first abortion the year prior, "This better not happen again." I feel the teen was placed in a desperate situation, not wishing to disappoint her family, particularily her mother after being warned, yet not fully understanding the devastating impact er actions would place on her and her family for the rest of their lives. Only when a teen stops denying the pregnancy can she confide in her parents. Even if a pregnant teen feels she has one supportive parent, many will still deny the pregnancy for a while. In an abortion procedure, timing is crucial, as most states have laws that ban abortioon after 22 weeks gestation, unless the mother's life is in danger. At least in a supportive environment, that is uncondidtional, non-threatening, the teen and parent/s can decide which is the better choice, given the circumstances. On the contrary, if the teen knows the news of her pregnancy will only bring verbal ridicule and harassment, and knows if she tries to obtain a legal abortion, her parents will be notified, this additional stress will only prolong the denial. This denial could go on throughtout the pregnancy, even throughout the birth process. The message this law sends is: A teenager can become a mother without parental notification, but she ca...

The Definition of Bivalve

The Definition of Bivalve A bivalve is an animal that has two hinged shells, which are called valves. All bivalves are mollusks.  Examples of bivalves are clams, mussels, oysters, and scallops. Bivalves are found in both freshwater and marine environments.   Characteristics of Bivalves There are about 10,000 species of bivalves.Bivalves range in size from less than a millimeter to close to 5 feet (e.g., the giant clam). A bivalves shell is formed of calcium carbonate that is secreted from the bivalves  mantle, which is the soft wall of the animals body. The shell grows as the organism inside gets bigger. Not all bivalves have externally visible shells - some are small, some are not even visible. Shipworms are a bivalve that doesnt have a very visible shell - their shell is made up of two valves at the worms anterior (back) end. Bivalves have a foot, but not an obvious head. They also dont have a radula or jaws. Some bivalves move around (e.g., scallops), some burrow  into the sediment (e.g., clams)  or even rocks, and some attach to hard substrates (e.g, mussels). Smallest and Largest Bivalves The smallest bivalve is thought to be the saltwater clam  Condylonucula maya. This species has a shell that is less than a millimeter in size. The largest bivalve is the giant clam. The valves of the clam may be over 4 feet long, and the clam itself may weigh over 500 pounds.    Bivalve Classification Bivalves are found in the  Phylum Mollusca, Class Bivalvia. Where Are Bivalves Found? Marine bivalves are found around the world, from polar regions to tropical waters and from shallow tide pools to deep-sea hydrothermal vents.   Feeding - Them and You Many bivalves feed by filter feeding, in which they draw water over their gills, and tiny organisms collect in the organisms gill mucus. The also breathe by drawing fresh oxygen from the water as it passes over their gills. When you eat a shelled bivalve, youre eating the body or a muscle inside.  When youre eating a scallop, for example, youre eating the adductor muscle. The adductor muscle is a round, meaty muscle that the scallop uses to open and close its shell. Reproduction Some bivalves have separate sexes, some are hermaphroditic (have male and female sex organs). In most cases, reproduction is sexual with external fertilization. The embryos develop in the water column and go through a larval stage before eventually developing their shell.   Human Uses Bivalves are some of the most important seafood species. Oysters, scallops, mussels, and clams are popular selections at just about every seafood restaurant. According to NOAA, the commercial value of bivalve harvests in 2011 was over $1 billion, just in the U.S.   This harvest weighed over 153 million pounds.   Bivalves are organisms particularly vulnerable to climate change and ocean acidification. Increasing acidity in the ocean is affecting the ability for bivalves to effectively build their calcium carbonate shells.   Bivalve Used in a Sentence The blue mussel is a bivalve - it has two equally-sized, hinged shells that fit together and enclose the animals soft body.
