Answer: Cell is the smallest structural unit of life. All living things in the world are made of small self-contained units called cells. Each cell is a collection of living matter enclosed by a cell membrane which function as a barrier that separate the cell from its surroundings. Most cells can perform all the functions associated with life.

Explanation: Living things have a level of complexity and organization not found in lifeless objects. These units generally too small to be seen with the naked eye, are organised into tissues. The organisms consisting of only a single cell are called "unicellular". Most of the organisms you are familiar with, however are multicellular, meaning they are made of many cells.

Answer:

The smallest structural unit that exhibits the characteristics of living things is CELL.

Explanation:

Cell has been defined as the smallest unit of life. It can be found in all living things although the number may differ. Unicellular organisms have only one cells while multi cellular organisms have many cells. In unicellular organisms, a single cell perform all the necessary metabolic activities; in multi cellular organisms, cells are differentiated into different types that perform specific functions. When group of cells work together to perform a specific function they are called tissue. Aggregation of tissues is called organ while aggregation of organs is called systems.

A star is not considered born until the process of nuclear fusion

jonny [76]

Star is a brilliantly glowing sphere of hot gas whose energyis produced by an internalnuclear fusion process. Stars are contained in galaxies. A galaxy contains not only stars, but clouds of gas and dust. These clouds are callednebulae, and it is in a nebula where stars are born. In the nebula is hydrogen gas which is pulled together by gravityand starts to spin faster. Over millions of years, more hydrogen gas is pulled into the spinning cloud. The collisions which occur between the hydrogen atoms starts to heat the gas in the cloud. Once the temperature reaches 15,000,000 degrees Celsius, nuclear fusion takes place in the center, or core, of the cloud. The tremendous heat given off by the nuclear fusion process causes the gas to glow creating a protostar. This is the first step in the evolution of a star. The glowing protostar continues to accumulate mass. The amount of mass it can accumulate is determined by the amount ofmatter available in the nebula. Once its mass is stabilized, the star is known as a main sequence star. The new star will continue to glow for millions or even billions of years. As it glows, hydrogen is converted into helium in the core by nuclear fusion. The core starts to become unstable and it starts to contract. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and starts to glow red. The star has now reached the red giant phase. It is red because it is cooler than the protostar phase and it is a giant because the outer shell has expanded outward. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths the star will take.
