Marine life, sea life or ocean life, is represented by the plants, animals and other organisms that live in the saltwater of the sea or ocean, or the brackish water of coastal estuaries.
At a fundamental level, marine life affects the nature of the planet. Marine organisms produce oxygen and sequester carbon.
Currently, of the approximately 12,000 extant reptile species and subspecies, only about 100 are classed as marine reptiles: extant marine reptiles include marine iguanas, sea snakes, sea turtles and saltwater crocodiles.

Write down their characteristics as well as the importance of the reefs
Working frequency, measured in hertz,(which determines its operating speed)
Processing data, performing arithmetical-logical operations and controlling all the other devices.
THE MOST IMPORTANT PART OF THE COMPUTER
CHIP AND BATTERY FOR BIOS
Is an integrated circuit that stores the computer booting program.
EXTERNAL CONNECTIONS
Ports for connecting to the network and external devices(keyboard,headphones ,USB memory cards, etc.)
IDE AND SATA CONNNECTIONS
SATA connections are the more modern ones. The picture shows the SATA (red) and IDE (blue) cables that connect the motherboard to the storage units.
ATX CONNECTOR
Joins the power supply to the motherboard through cables
RAM MEMORY SLOTS
RAM memory modules are plugged into these. These differ from other slots in that they include clips to hold the module in place
CHIPSET
Is a set of chips on the motherboard that carries out communications between the microprocessor and the different components connected to the motherboard. It controls the operating mode of the board and determines its performance and characteristics.
MICROPROCESSOR SOCKET
A thermal paste is added under the sink to improve heat dispersal and, finally, the microprocessor is located above the socket.
