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.

Makhluk Hidup dalam Ekosistem Alami Selamat datang di Lahiya, situs (blog) sederhana yang berbagi ilmu dan pengetahuan dengan penuh keikhlasan. Dan, pada kesempatan kali ini, kami bakal sharing pengetahuan mengenai Makhluk Hidup dalam Ekosistem Alami, pembahasannya meliputi Populasi dan Komunitas Makhluk Hidup, Faktor-faktor yang Mempengaruhi Populasi dan Bentuk-bentuk Ekosistem Alami.

Populasi dan Komunitas Makhluk Hidup

Populasi dalam kumpulan individu sejenis yang umumnya menghuni daerah spesifik. Populasi memiliki peluang untuk berinteraksi yang tampak berbentuk persaingan untuk mempertahankan diri atau kerja sama untuk mempertahankan jenisnya. Satu lokasi umumnya tidak ditempati oleh satu jenis populasi saja namun ditempati oleh beragam jenis populasi makhluk, umpamanya di populasi air tawar tidak cuma ditempati oleh kumpulan ikan saja, namun ada juga tumbuhan air, kura-kura, serta kumpulan hewan yang lain.

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. As i said before, early detection is the key of peritoneal mesothelioma treatment [] success since the cancer cell spread very fast.

Populasi di darat

Ukuran populasi banyak variasi dari waktu ke waktu. Beberapa populasi mempertahankan ukuran populasinya secara konstan, sedangkan populasi lain alami ledakan penambahan jumlah yang amat besar. Satu diantara contohnya yaitu populasi burung red grouse (lagopus scaticus) satu jenis burung di Skotlandia barat laut. Populasi burung ini ada di dua tempat yang terpisah. Tempat pertama memiliki luas 49 ha, sedangkan yang satunya lagi memiliki ukuran 47 ha. Di satu tempat pertumbuhan burung ini relatif konstan, namun di tempat satunya lagi alami pelonjakan populasi tetapi beberapa th. lantas terjadi penurunan kembali.

Hal semacam ini dapat terjadi lantaran, makanan pokok jenis burung ini yaitu tanaman heather (colluna vulgaris). Tanaman muda dan sedang tumbuh amat disenangi oleh jenis burung ini. Hingga pembakaran tempat di salah satu tempat mengakibatkan ketersediaan tanaman muda melimpah. Populasi burung ini pun bertambah dengan cepat. Tetapi, perkembangan ini kembali lagi seperti aslinya setelah tempat dikembalikan seperti semula beberapa th. kemudian, populasi jadi konstan kembali.

Faktor-faktor yang Memengaruhi Populasi

Migrasi, aspek ini dibagi jadi dua aspek lagi, salah satunya yaitu masuknya jenis populasi yang sama hingga mengakibatkan keseimbangan antara jumlah populasi serta jumlah makanan jadi terpengaruh. Keluarnya beberapa populasi untuk mencari tempat yang lebih baik juga memengaruhi perkembangan populasi.

  • Kompetisi, komponen dalam populasi juga memungkinkan munculnya persaingan hingga mengakibatkan dampak pertumbuhan pada populasi.
  • Penyakit, hal semacam ini susah untuk dijauhi oleh populasi hingga ini salah satu penyebab paling utama musnahnya populasi.
  • Mortalitas, aspek ini sebagai penentu akhir yang dikarenakan oleh berbagai aspek lain, seperti kekurangan sumber makanan, penyakit, stres, dan lain-lain.
  • Komunitas yaitu kumpulan populasi beragam jenis makhluk hidup yang saling berhubungan. Hubungan itu bisa berbagai macam:
  1. Netral, di antara populasi tidak ada saling memengaruhi, umpamanya populasi semut dan lebah.
  2. Persaingan, terjadi persaingan antar populasi, umpamanya populasi zebra dan rusa
  3. Mutualisme, bila hubungan antar populasi saling menguntungkan, umpamanya antara populasi semut serta kutu pohon.
  4. Predasi, bila anggota populasi bakal dikonsumsi oleh anggota populasi yang lain, yang makan disebut dengan predator, yang dikonsumsi disebut dengan mangsa, umpamanya antara populasi singa serta rusa.
  5. Parasitisme, bila salah satu populasi jadi parasit dari populasi yang lain. Umpamanya antara pohon dengan benalu
  6. Komensalisme, hubungan antar populasi, di mana yang satu untung yang lain tidak rugi, umpamanya antara pohon dengan anggrek.
  7. Ekosistem yaitu kesatuan dari komunitas dengan lingkungan hidupnya. Ekologi yaitu pengetahuan yang mempelajari hubungan timbal balik antara makhluk hidup dengan lingkungan hidupnya

Lingkungan hidup organisme ada 2 yakni:

  • Lingkungan abiotik: tanah, air, udara, cuaca, iklim, suhu, cahaya dan lain-lain.
  • Lingkungan biotik: organisme yang lain (semua m. h. yang ada dalam sebuah ekosistem)

Aliran Daya dalam Komunitas Alami

Terpeliharanya satu komunitas bergantung pada aliran daya lewat pelaku rantai makanan dalam komunitas itu. Tiap komunitas mempunyai pelaku rantai makanan sebagai berikut ini:

  • Produsen, yakni satu jenis makhluk hidup berhijau daun yang merubah daya surya jadi daya kimia dalam jaringannya.
  • Konsumen pertama, herbivora, yakni satu organisme pemakan tumbuhan.
  • Konsumen kedua, karnivora, satu organisme pemakan herbivora.
  • Konsumen ketiga, karnivora pemakan karnivora yang lain. Tetapi ada organisme yang secara fungsional termasuk juga konsumen pertama, kedua serta ketiga yakni manusia.
  • Parasit, yakni organisme yang memperoleh makanan yang sudah diolah oleh organisme lain ditempat dia hidup
  • Pemakan bangkai, hewan yang hidup dari kotoran atau tumbuhan yang udah membusuk.
  • Pengurai, bakteri, mikroba yang menguraikan organisme atau sampah organik yang melepaskan zat kimia atau panas ke lingkungan untuk kemudian diserap kembali oleh tumbuhan hidup.

Aliran Daya dalam Ekosistem

Bentuk-bentuk Ekosistem Alami

Tiap komponen yang ada di alam saling memengaruhi serta berhubungan hingga terjadi aliran daya serta materi yang terjadi pada satu system serta hal semacam ini kerapkali disebut dengan satu ekosistem (dari kata ecologycal sistem). Ekosistem ini mencakup komponen biotik (organisme hidup yang lain) serta komponen biotik (tanah, air, udara).

Dalam satu ekosistem yang bisa berdiri dengan sendiri mesti memenuhi syarat berikut ini:

  • Sumber daya dan system kehidupan yang mampu memproses daya untuk keperluan komponen-komponen dalam kehidupan.
  • Terdapatnya beberapa zat kimia, zat diperlukan dan mekanisme yang mengatur keseimbangan beberapa zat antara komponen biotik serta biotik dalam ekosistem. Beberapa zat kimia yang diperlukan oleh satu ekosistem terutama yaitu H2O, CO2, serta O2 dan zat hara yang lain.

Bila kriteria diatas terpenuhi, secara alami bakal terbentuk beragam ekosistem alami, baik ekosistem darat ataupun ekosistem pesisir. Ekosistem darat terdiri dari ekosistem yang menetap langsung diatas tanah serta ekosistem perairan air tawar, seperti danau. Ekosistem pesisir terdiri dari ekosistem estuari, pesisir, serta laut.

Untuk memelihara kesetimbangan satu ekosistem, beberapa zat kimia serta unsur hara yang lain mesti seimbang diantara komponen biotik serta biotik. Peristiwa ini disebut dengan sebagai siklus bioglokimia.

Ekosistem alami ini bisa dipengaruhi oleh beberapa aspek alam juga. Umpamanya dampak geografis, angin, air laut, dan sebagainya. Satu ekosistem yang udah stabil bakal berubah oleh beberapa dampak diatas. Perubahan-perubahan ini umumnya akan diawali dari perubahan kecil dan akan terus bertambah sampai terwujud ekosistem baru yang amat berbeda dengan ekosistem sebelumnya.
