Because we wanted to focus specifically on “speed” rather than general measures of quality, we custom-designed a scale to rank schools based on this highly desirable “fast factor.” Specifically, we researched each online college and asked ourselves the following questions: Does the school offer bachelor’s degrees that one could complete in less than four years? What about associate’s degrees in less than two years? Are there many short certificate options for students who want to quickly augment their skills in an established field? Are there “accelerated” degree paths and options for students who want to earn a combined bachelor’s/master’s degree? Does the school offer credit for life/work experience and past academic coursework in order to help students move ahead on their degree path? Does the school offer multiple course formats so that students have the option to start several times a year and/or to choose between classes of varying lengths? But don’t worry – we still considered graduation rate and tuition costs as well! We hope this has been helpful in providing information about fast online degrees from accredited colleges. There are many fast online degree programs available, and we encourage you to do a broad search to find the program that’s best for you.

Jadi, Protozoa yaitu hewan pertama. Protozoa adalah grup lain protista eukariotik. Terkadang pada algae serta protozoa kurang terang ketidaksamaannya. Umumnya Protozoa cuma bisa diliat dibawah mikroskop.

Sebagian organisme memiliki karakter pada algae serta protozoa. Sebagai contoh algae hijau Euglenophyta, selnya berflagela serta adalah sel tunggal yang berklorofil, namun bisa alami kehilangan klorofil serta kekuatan untuk berfotosintesa. Seluruh spesies Euglenophyta yang dapat hidup pada nutrien komplek tanpa ada sinar, sebagian ilmuwan memasukkannya kedalam filum protozoa.

Malignant peritoneal mesothelioma is a rare type of mesothelioma which attacks the lining of abdomen also known as peritoneum. Malignant peritoneal mesothelioma (MPM) is a universally fatal disease affecting 20% to 30% of the mesothelioma cases. It's was first described by Miller and Wynn in the year 1908. According to the statistics, in the past two decades, the incidence of malignant peritoneal mesothelioma cancer has increased. Peritoneal mesothelioma affects the lining of the abdomen also known as peritoneum. The location of malignant cell is human's abdominal lining and because of that, MPM can sometimes known as abdominal mesothelioma. However, most common term used to describe this type of cancer is peritoneal mesothelioma. The main cause of MPM in humans is asbestos. Asbestos typically is the one of most commonly roofing materials since it is not only cheaper but is easy to fix on a roof. Asbestos exposure contributed to almost 70 to 80 percent of mesothelioma lung cancer. Humans come into contact with asbestos when they swallow or inhale the fibers. Asbestos inhalation may increase risk to develop asbestos related diseases, most importantly mesothelioma. Asbestos was completely banned in UK since it was recognized to be a serious health hazard, and it is now responsible for about 4000 deaths each year and many cases of serious disease. The people at increase risk of developing health asbestos related disease are those whose work brings them into direct contact with asbestos such as builders, heating engineers, roofers and demolition workers. In addition to mesothelioma, asbestos exposure will increase the risk of other health problems such as lung cancer, asbestosis (chronic lung ailment) and other type of cancer such as larynx and kidney cancer. Symptoms of Malignant Peritoneal Mesothelioma It can takes such a long time for cancer to develop the symptoms and sometimes may take up to 30 years, between exposure to asbestos and the start of the disease. Most common symptoms of the disease are abdominal pain, abdominal swelling, abnormal weight loss, anemia, easy fatigue, nausea and vomiting. Abdominal pain and swelling result from fluid accumulation in the abdominal cavity. Other than that, people can easily get fever when the disease starts to shows its symptoms. Among the symptoms stated above, abdominal pain is the most common reported initial symptoms of MPM. Unexplained night sweats and blood coagulation problems are less frequent symptoms occurring when the cancer develops. If the cancer cells spread to the other part of the body, the symptoms may lead to trouble swallowing or swelling of the neck and face. Diagnosis of Abdominal Mesothelioma It is very difficult to diagnose peritoneal mesothelioma since there is no defined system so far that can differentiate the stages of the development of cancerous tumor cells. If required, TNM staging system normally used to detect the cancer in stages. Other than that, Serum mesothelin-related protein (SMRP) may be a potentially useful serum marker used to diagnose and to follow-up the cancer progression. Computer tomography (CT) findings may be a useful tool in detection and characterization of peritoneal mass. Malignant Peritoneal Mesothelioma is a deadly neoplasm. MPM's diagnosis is difficult to perform since the symptoms will take a long time to show up. Early detection is the key in peritoneal mesothelioma treatment since the cancer cell normally spread very fast. Peritoneal Mesothelioma can be regarded as a very dangerous cancer among other cancer.However we can prevent this problems from occur to you and your family.

Jika keadaan lingkungan rumah mendadak jadi buruk, Protozoa membuat kista. Serta jadi aktif lagi. Organel yang ada didalam sel diantaranya nucleus, tubuh golgi, mikrokondria, plastida, serta vakluola. Nutrisi protozoa berbagai macam. Ada yang holozoik (heterotrof), yakni makanannya berbentuk organisme yang lain,.

Ada juga yang holofilik (autotrof), yakni bisa mensintesis makanannya sendiri dari zat organic dengan pertolongan klorofit serta sinar. Tidak hanya itu ada yang berbentuk saprofitik, yakni memakai bekas bahan organic dari organisme yang sudah mati adapula yang berbentuk parasitik. Jika protozoa dibanding dengan tumbuhan unisel, ada banyak ketidaksamaan namun ada persamaannya.

Protozoa yaitu mikroorganisme mirip hewan yang disebut satu diantara filum dari Kingdom Protista. Semua aktivitas hidupnya dikerjakan oleh sel tersebut dengan memakai organel-organel diantaranya membran plasma, sitoplasma, serta mitokondria. Ciri umum :

  • Organisme uniseluler (bersel tunggal)
  • Eukariotik (mempunyai membran nukleus)
  • Hidup soliter (sendiri) atau berkoloni (grup)
  • Biasanya tidak bisa bikin makanan sendiri (heterotrof)

Perkembangbiakan bakteri serta amuba Perkembangbiakan amuba serta bakteri yang umum dikerjakan yaitu dengan membela diri. Dalam keadaan yang sesuai sama mereka mengadakan pemisahan secara tiap 15 menit. Momen ini diawali dengan pemisahan inti sel atau bahan inti jadi dua. Lalu diikuti dengan pemisahan sitoplasmanya, jadi dua yang masing=masing menyelubungi inti selnya.

Berikutnya sisi tengah sitoplasma menggenting diikuti dengan pembelahan sitoplasma. Pada akhirnya sesudah sitoplasma sudah betul-betul terpisah, terbentuknya dua sel baru yang masing=masing memiliki inti baru serta sitoplasma yang baru juga. Pada amuba apabila keadan kurang baik, umpamanya hawa sangat dingin atau panas atau kurang makan, amuba bakal membuat kista.

Didalam kista amuba bisa membelah jadi amuba-amuba baru yang lebih kecil. Apabila kondisi lingkungan sudah baik kembali, dinding kista bakal pecah serta amuba-amuba baru tadi bisa keluar. Berikutnya amuba ini bakal tumbuh setelah tiba pada ukuran spesifik dia bakal membelah diri seperti awal mulanya.

Morfologi Protozoa

jenis protosoa


Seluruh protozoa memiliki vakuola kontraktil. Vakuola bisa bertindak sebagai pompa untuk keluarkan keunggulan air dari sel, atau untuk mengatur tekanan osmosis. Jumlah serta letak vakuola kontraktil tidak sama pada tiap spesies. Protozoa bisa ada berbentuk vegetatif (trophozoite), atau bentuk istirahat yang dimaksud kista.

Protozoa pada kondisi yg tidak untungkan bisa membuat kista untuk menjaga hidupnya. Waktu kista ada pada kondisi yang untungkan, bakal berkecambah jadi sel vegetatifnya. Protozoa tak memiliki dinding sel, serta tak memiliki kandungan selulosa atau khitin seperti pada jamur serta algae.
