1. Organization is one characteristic of life. An example of this is the levels of biological organization. The complex organization of life begins with atoms, the basic unit of matter. The atoms then combine to form small molecules and then begin to form larger molecules within a cell. Eventually the organism grow to form new populations. Each level progresses into something bigger.
2. The second characteristic of life is, life requires materials and energy. All living organisms require a source of energy. For plants, they require sunlight or solar energy. Animals require food for nutrients and energy. example of this is plants requiring photosynthesis.
3. The third characteristic of life is, living organisms maintain homeostasis. In order for animals to live they must have the abilities to live in their environment; which means they have to have the ability to adjust to physiological factors in their environment. Factors like temperature, moisture level, acidity and much more. For example, an outside dog has to have the ability to adjust to a season change, like winter. They must adapt to the colder temperatures, the new moisture levels, and many other things. If the outside dog does not adapt to these changes and maintain homeostasis, they will not survive.
4. The Fourth characteristic of life is, all living organisms has to be able to reproduce and develop. All living things has to come from another living thing, and then they have to be able to reproduce another living organism such as themselves. Such as a human reproduces a baby. That baby came from a living organism, and that baby shares characteristics from its of...

...iffuse across across the membrane with zero energy. Molecules like, carbon dioxide, oxygen, alcohol, and glycerol; can freely move across the cell because they are none charged molecules that require no energy. The molecules are a Substances can cross the plasma membrane through passive transport or facilitated transport. If a substance enters the cell through passive transport, the plasma membrane is completely permeable to that substance, meaning that the substance is following its concentration gradient. This means it is moving from a high concentration to a low concentration. During facilitated transport, a substance requires an expenditure of energy and/or the help of a carrier protein to cross the membrane. This is generally because the substance is going against its concentration gradient; meaning it is moving from a low concentration to a high concentration.

- The importance of LMO Since human population has increased dramatically, the demand for food is increasing also to fulfil the myriad population. Moreover, climate changes caused the natural disasters like flood and drought to happen more often, resulting in uncontrollable disruption to crops and livestocks. Hence, to overcome these problems, scientists come out with a solution, Living Modified Organisms (LMOs) which is also known as Genetically Modified Organisms (GMOs). One of the intentions of LMOs is to overcome food crisis.... [tags: climate change, genetically modified organisms]

- Issac Leib Peretz once said, “Time is change, transformation, evolution. Time is eternal sprouting, blossoming, the eternal tomorrow.” In PBS’s Documentary Great Transformations, the transformation from the first living organism to what we are today was discussed and how most organisms have very similar genes and characteristics. How fish used to colonize land and land mammals evolved to sea creatures. For instance, the whale, the biggest mammal that lives in the water, was found to have had legs and used to dwell on land millions of years ago.... [tags: Gene, Organism, Evolution, Biology]

- The seven characteristics that are shared by all living things start with reproduction. This act is not necessarily required for individual organisms to survive, but is crucial for an entire species to thrive. For an organism to be able to reproduce it must be with its own kind; for example, humans with other humans or dogs with other dogs. Next is growth and development, cells enlarge and divide, the more cells there are, the larger the organism will become. Genetic information is passed down to them from their maternities; this will govern their growth as they mature and age.... [tags: Eukaryote, Bacteria, Organism, Plant]

- Introduction In nature there is a system, which operates, in such a way that there is no waste. Nutrients and metabolisms go through a cycle, going through different transformations. One simple cycle is the process of exhalation of carbon dioxide. Animals and human beings exhale carbon dioxide, which is taken in by plants, as it is an important component for its food making process called photosynthesis. Leaves that fall to the ground are naturally broken down into nutrients for the soil and fertilisers for trees.... [tags: Buildings as Living Organisms]

- The Role of Water in Living Organisms Water is one of the most abundant molecules on planet earth; it is found in vast amounts not only in earthly enviroments (oceans, lakes and rivers), but is also present in the atmosphere, and as solid ice in the two poles. Consequently it is rather logical that water plays an important role in biological life: the origins of life occurred in water and life itself wouldn't be able to continue in it's absence . I will now describe the structure of a water molecule.... [tags: Biology Essays]

- Water is one of the most abundant substances on the planet. It can be found naturally in all three states; solid (ice), liquid (water), and gas (steam). However, chemically it is very unusual. For example, water molecules are slightly polar i.e. they have a positive and negative end. Due to this difference in electro-negativity the slightly positive charge on the hydrogen atom is attracted to the slightly negative charge on the oxygen atom in another molecule. This bond is called a hydrogen bond and is what causes the water to have its unusual properties.... [tags: Biology Essays]

- Nutrition is the essential organic nutrients living organisms require for growth, maintenance, reproduction and repair. This is an essential process for the organism’s survival. Living organisms require energy to survive; this energy is derived from nutrients, or food. Ingestion, digestion, absorption and excretion are the stages of processing food. Heterotrophs are organisms which cannot synthesise their own food and are therefore totally reliant on organic substances for nutrition. Animals are heterotrophs and are divided into three categories; herbivores, carnivores and omnivores depending on how they obtain their food.... [tags: Biology ]

- The Importance Of Water To Living Organisms Water is normally the most abundant component of any living organism. As most human cells are approximately 80% water and 60% of the human body is made up of it, it is extremely important in many different ways to both the survival and the well being of living organisms. Evolutionists believe that life probably originated in water and even today thousands of organisms make their home in it. Water also provides the medium in which all biochemical reactions take place.... [tags: Biology Essays]

- Water has a great number of roles in living organisms, this is largely to do with the structure and covalent bonding in a single water molecule, and between water molecules. Around 75% of the earth is covered in water, and it is reffered to as the most important Biochemical. Its chemical symbol is: H2O In a water molecule there are two bonding pairs and two non-bonding pairs of electrons. These four pairs of electrons repel one another, forming a tetrahedral pattern. Because they repel they are as far from each other as possible.... [tags: Biology Essays]

- The Importance of Diffusion to Living Organisms Diffusion is basically the movement of chemical species (ions or molecules) under the influence of concentration difference. The species will move from the high concentration area to the low concentration area till the concentration is consistent in the whole system. Diffusion mostly occurs in gases and liquids as these can move freely. The main features of an efficient diffusion system would be that it has a large surface area, thin membrane and a continuous supply of substances.... [tags: Papers]
