Interactions with the environment- organisms are open system that exchange material and energy with their surroundings. 6. Energy and life: all organisms must perform work‚ which required energy.

Around 4.6 billion years ago‚ our universe was born by accretion from the solar nebula known as the Big Bang. As the sun heated up‚ this orbiting matter accumulated and unavoidable mass of larger bodies collide to successively create protoplanets with its own gravitational pull. During this period‚ Earth was nothing but molten rock from the collision with other bodies and volcanoes‚ temperature reaching over 2‚000 fahrenheit. Not only that‚ but Earth then‚ would’ve been toxic to humans and modern

and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining; it takes in nutrients

Eukaryotic & Prokaryotic Cells Introduction: The Cell: The cell is a functional unit of all living organisms. Cells have evolved into two fundamentally different types‚ eukaryotic and prokaryotic‚ which can be distinguished on the basis of their structure and the complexity of their organization. The simplest organisms which consist of one cell are called prokaryotes. More complex organisms are called eukaryotes and they consist of many cells. Objectives: * Define the terms: Eukaryotes

introduction of a new species from elsewhere can greatly affect the balance of nature. What is a virus? A virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms‚ from animals and plants to bacteria and archaea. All viruses have genes made from either DNA or RNA‚ long molecules that carry genetic information; all have a protein coat that protects these
