The process of change that has transformed life on Earth form its earliest beginnings to the diversity of organisms living today.
The scientific study of life.
Refer to those properties that arise from the collaborative functioning of a system, but do not belong to any one part of that system.
Reductionism is the reduction of complex systems to simpler components that are more manageable to study
Is an approach that attempts to model the dynamic behavior of whole biological systems based on a study of the interaction among the system's parts.
Is a subdivided by internal membranes into various membrane-enclosed organelles. Most Eukaryotic cells, the largest organelle is the nucleus, which contains the cell's DNA.
Are much simpler and generally smaller than Eukaryotic cells. The DNA is not separated from the rest of the cell by enclosure in a membrane-bounded nucleus.
The process by which the information in a gene directs the production of a cellular product, is called gene expression
Is the entire library of genetic instructions that an organism inherits is called its genome.
An approach that researches use to studying whole sets of genes of a species as well a comparing genomes between species.
The most common form of regulation in living systems is Negative Feedback, in which accumulation of an end product of a process slows that process.
The end product speeds up its own production. The clotting of your blood in response to injury is an example.
Domain of Life
- a) Domain Bacteria
- b) Domain Archaea
- c) Domain Eukarya
The mechanism of evolutionary adaptation-because the natural environment "selects" for the propagation of certain traits among naturally occurring variant traits in the population.
From the Latin verb meaning "to know" Science is a way of knowing-an approach to understanding the natural world.
Is a tentative answer to a well framed question-an explanation on trail. It is usually a rational accounting for a set of observations, based on the available data and guided by inductive reasoning.
Is generally used after the hypothesis has been developed and involves logic that flows in the opposite direction from the general to the specific.
One that is designed to compare an experimental group.
- Is much broader in scope than hypothesis. A theory is general enough to spin off many new, specific hypotheses that can be tested.
- A theory is supported by a much greater body of evidence.
