6 Characteristics of living things
Made of cells, organisms need to metabolize energy, respond to stimuli, reproduce, grow and develop, and evolve over time
The genetic code used by all living things on Earth and some nonliving things such as viruses. It is made up of nitrogenous base pairs attached to a sugar and a phosphate group. The sugar and the phosphate group make up the backbone. The four nitrogenous bases are Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Adenine always pairs with Thymine while Guanine always pairs with Cytosine. It is usually in the shape of a double helix. A gene is a single trait of an organism
Response to stimuli
One of the six characteristics of life, stimuli are physical or chemical changes in the internal or external environment.
The variety of life, there are over 1.5 million identified species of organisms on the Earth
The chemical compounds that provide physical structure and that bring about movement, energy use, and other cellular functions.
The sum of all the chemical reactions that take and transform energy and materials from the environment.
Growth and Development
The growth of living things as a result of the enlargement and division of existing cells. Development is the process by which an organism becomes an adult.
The production of new organisms similar to the parent that created them. It is not immediately necessary to the survival of the individual organism but it is necessary to the continuation of the species.
A statement that forecasts what would happen in a test situation if the hypothesis is true
A set of related hypotheses that is confirmed to be true many times, that can explain a great amount of data.
A normal standard against which the experimenter can compare against the experimental group
A group that is only different from the control group by one factor, this factor is the independent or manipulated variable.
