IVF can result in Overian Hyperstimulation Syndrome. In ivf, ovaries of intended mother (or egg donor) are stimulated to produce more than 1 high quality eggs. The hormones and drugs used to stimulate ovaries, can have side effects leading to condition called overian hyperstimulation syndrome 3. Ectopic pregnancy : IVF can lead to Ectopic pregnancy in which the pregnancy occurs outside the uterus 4. IVF success rates are much lower than 100%.
The CVS is conducted within the first 11 to 13 weeks of pregnancy, in this procedure a sample of cells is taken from the placenta and tested for genetic defects. Amniocentesis is only performed in women over 35 and is done 15 to 20 weeks into pregnancy. It consists of 20 mL of amniotic fluid getting extracted from the womb because this fluid has cells shed from the baby and is tested for different conditions. In some cases, the mother uterus is larger because the presence of extra amniotic fluid and at birth the placenta is small. For some, Edwards syndrome is only detected after the infant is born.
Based upon differing water salinities, the experiment tests the most favorable salinity level of Littorina spp. by measuring the movement produced. The experiment used a separate exposure treatment with the four treatments being 10, 20, 30 and 40 parts per thousand (ppt) saltwater. In trial 1, a moderate and a lower salinity environment were set up to determine which salinity the snails would best adapt to; thus, producing the most movement. Two separate arenas were created in 20 cm glass container with 200mL of 10 ppt and 30 ppt salinity water in their respective arenas, with 14 replicates being used.
The built-in probe in the chamber measured the dissolved oxygen concentration in the chamber’s water (mg/L), which could reflect the oxygen consumption rate of goldfish. After the fish accommodated to the new environment, the oxygen concentration data were collected every 20 seconds for 10 minutes by the Logger Lite program. The data were then plotted into a scatter chart and analyzed with a linear trendline, to obtain
Over 100 million sharks are murdered by humans every year, and it’s a high number for any animal but it’s endangering to sharks because they don’t breed very quickly due to their biological composition (NewsCurrents Read to Know). Sharks reproduce very slowly and they can’t keep up with the rate that humans are killing them off at. With that inbalance, they’re getting closer and closer to extinction everyday, but with a ban on finning that would cut down over half of those casualties and keep the sharks from dying off. Consequently, because they’re being killed off in large unmoderated amounts there a species of sharks already extinct and in "Bad to the Bone", written by Michael A. Rivlin, he writes “Because of such biological profiles, most shark fisheries have experienced brief booms, followed by long busts. To take one notorious example, in 1961 Norwegian longliners began catching porbeagle sharks in the Northwest Atlantic.
They are strictly herbivores as they can eat up to 110 pounds of sea grass a day. The Dugong has a fascinating mouth. Their horseshoe shaped snout is located ventrally and faced down so that they can graze easier off the ocean floor. Their lips are extremely muscular and are covered in sensitive bristles. These bristles sense the presence of sea grass and the Dugong will grasp it and begin to rip it from the ground.
Kelp is one of the very bright, colorful plants found in the ocean. Kelp depends on sunlight and is found no deeper than 131 feet.Oar weeds is another common plant in the Pacific Ocean. Oar weed is a large seaweed that dark brown and can grow to three meters long. Oarweed was used as a fertilizer in the 18th century. A common animal of the pacific ocean is the reef triggerfish or the"Humuhumunukunukuapuaa.” This fish is the state fish of Hawaii.
Another thing that effects the blue crab 's ecosystem is its environmental threats. To begin, one of the environmental threats that blue crabs face is pollution. In the text, it states, “Approximately 6.4 million tons of plastic and other debris enter the oceans each year. And every year., more than 1 million marine animals die from eating or getting caught in this debris,” (Dignan 13). This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem.
B. Plastic pollution is detrimental to most forms of marine-centric life. 1. “Approximately 100,000 marine creatures of nearly 300 species die each year from plastic consumption
1. 90-100 million tons are killed and wiped off the planet each year. Consisting of some of the most beautiful creatures on the planet. Fish are a primary food source to 3.5 billion people worldwide and the depletion of the species is leaving millions of people hungry. Over fishing is a huge problem that needs to be stopped.
