Self-organization and self-replication are the hallmark of living systems. Non-living molecules sometimes show those features under proper conditions. For example, Martin and Russel showed that cell membranes separating contents from the environment and self-organization of self-contained redox reactions are the most conserved attributes of living things. They argue that inorganic matter like that would be life's most likely last common ancestor.
In this hypothesis, RNA is said to work both as an enzyme and as a container of genes. Later, DNA took over its genetic role.
The RNA world hypothesis proposes that life based on ribonucleic acid (RNA) pre-dates the current world of life based on deoxyribonucleic acid (DNA), RNA and proteins. RNA is able both to store genetic information, like DNA, and to catalyze chemical reactions, like an enzyme. It may have supported pre-cellular life and been a major step towards cellular life.
There are some pieces of evidence which support this idea:
This idea suggests that proteins worked as enzymes first, producing metabolism. After that DNA and RNA began to work as containers of genes.
This idea also has some evidences which supports this.
In this scheme membranes made of lipid bilayers occur early on. Once organic chemicals are enclosed, more complex biochemistry is then possible.
This is the idea suggested by Arrhenius, and developed by Fred Hoyle, that life developed elsewhere in the universe and arrived on Earth in the form of spores. This is not a theory of how life began, but a theory of how it might have spread. It may have spread, for example, by meteorites.
Some propose that early Mars was a better place to start life than was the early Earth. The molecules which combined to form genetic material are more complex than the "primordial soup" of organic (carbon-based) chemicals that existed on Earth four billion years ago. If RNA was the first genetic material, then minerals containing boron and molybdenum could assist in its formation. These minerals were much more common on Mars than on Earth.
In Christianity, some people reject the idea of evolution. They believe that the Earth is only a few thousand years old. This is known as Young Earth Creationism. However, the Bible does not explicitly state the age of the Earth, only that 'In the beginning, God created the heavens and the earth.' (Genesis 1:1)
God is portrayed as the creator of all things, and the originator of life on Earth (Genesis 1 & 2).
Timeline of the 2006 Atlantic hurricane season
Below is a timeline of the 2006 Atlantic hurricane season, listing all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation. The 2006 Atlantic hurricane season was a season in which an El Niño event stopped much tropical cyclone activity, especially later in the season. The season officially began on June 1, 2006, and lasted until November 30. For convenience and clarity, in the timeline below, all landfalls are bolded. The timeline also includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned on, have been included.
The graphical bar above gives a brief overview of storm activity during the season, and for convenience, the storm's maximum intensity is included as a color bar. Tropical Storm Zeta from 2005 persisted into 2006, therefore a January section has been included in the text timeline.
Atlantic Standard Time Zone
The Atlantic Standard Time Zone (AST) is a geographic region that keeps time by subtracting four hours from Greenwich Mean Time (GMT), resulting in GMT-4 (UTC-4). The clock time in this zone is based on the mean solar time of the 60th degree meridian west of the Greenwich Observatory.
The Canadian provinces of New Brunswick, Nova Scotia and Prince Edward Island keep time by subtracting four hours from UTC. So does Bermuda, an island territory in the North Atlantic. In the summer, both places use daylight saving time. They keep "Atlantic Daylight Time (ADT)" (UTC-3) in the summer.
Other parts of the world that keep time by subtracting four hours from UTC include: many Caribbean islands, including Puerto Rico, the U.S. Virgin Islands, and several South American countries, such as Paraguay, Chile, Bolivia, and parts of Brazil. Venezuela used AST until December 9, 2007, when it switched to , but switched back to AST on May 1, 2016, at 2:30 a.m. local time.
Figueirense FC
Figueirense Futebol Clube, also known as Figueirense, is a Brazilian football team in Florianópolis, Santa Catarina.
In 1921, the club was founded as Figueirense Football Club.
In 1932 the team won their first state championship.
From 1935 to 1937, Figueirense was three times in a row Catarinense champion.
In 1973, Figueirense was the first team of Santa Catarina state in Campeonato Brasileiro Série A.
In 1987, the club played at Campeonato Catarinense Second Division, and won the promotion to the First Division.
In 2001, the club was Campeonato Brasileiro Second Division runner-up, and was promoted to the following year's First Division.
From 2002 to 2004, Figueirense was three times in a row Campeonato Catarinense champion.
The stadium of Figueirense is Estádio Orlando Scarpelli. It was built in 1961. Its a maximum capacity is 19,908 people.
C Sharp (programming language)
C# (pronounced "see sharp") is a computer programming language. It is developed by Microsoft. It was created to use all capacities of .NET platform. The first version was released in 2001. The most recent version is C# 8.0, which was released in September 2019. C# is a modern language. C#'s development team is led by Anders Hejlsberg, the creator of Delphi.
Today, C# can be run on most platforms (Windows, Linux, etc.) without changing the source code. C# can be run on the Xbox 360 platform with a special framework.
C# code is similar to C++ and Java code. The CLR (Common Language Runtime) is needed in order to run a C# program.
/* This is a simple program in C#.
using System;
namespace HelloWorld
* This program asks for input from the user, i.e. a name. It then prints "Hello [name]", replacing [name] with whatever the person typed in.
using System;
namespace HelloWorld
C# can be edited in a number of IDEs (Integrated Development Environments), some of which are listed below:
Windows:
Mac OS X:
Unix/Linux:
Wilmington, North Carolina
Wilmington is a city in New Hanover County, North Carolina, United States.
The population was around at 96,000 during 2006;. It is the county seat of New Hanover County. It was named in honor of Spencer Compton, the Earl of Wilmington, who was Prime Minister at the same time as George II was King of England.
It was the site of the 1898 insurrection where many white people killed African-American politicians in the city. It is seen as the only coup d'état on American soil.
Plantation Key
Plantation Key is an island in Monroe County, Florida, United States. It is in the upper Florida Keys on U.S. Route 1 (or the "Overseas Highway"), between Key Largo and Windley Key.
Oak Island, North Carolina
Oak Island, North Carolina is a town mostly on Oak Island (which also contains the town of Caswell Beach and the North Carolina Baptist Assembly at Fort Caswell) in Brunswick County, North Carolina; a small part of the town extends onto the mainland north of the island's bridge. 6,571 people lived there at the 2000 census. It was founded in 1999 by the consolidation of the towns of Long Beach and Yaupon Beach. Its main industry is tourism; the town has about 30,000-40,000 people in the summer.
Avegno, Switzerland
Avegno was a municipality of the district of Vallemaggia in the canton of Ticino in Switzerland. On 20 April 2008, Avegno and Gordevio merged to form the new municipality of Avegno Gordevio.
