Biology 1610

The process of change that has transformed life on Earth from its earliest beginnings to the diversity of organisms living today.

The scientific study of life.

Are due to the arrangement and interactions of parts as complexity increases. Ex- although photosynthesis occurs in an intact chloroplast, it will not take place in a disorganized test-tube mixture of chlorophyll and other chloroplast molecules.

Is an approach that attempts to model the dynamic behavior of whole biological systems based on a study of the interactions among the system's parts.

Has already had dire effects on life-forms and their habitats all over planet Earth. Ex- Polar bears, Ice.

Is subdivided by internal membranes into various membrane-enclosed organelles.

The DNA is not separated from the rest of the cell by eclosure in a membrance-bounded nucleus.

Deoxyribonucleic acid, DNA is the substance of genes.

The units of inheritance that transmit information form parents to offspring.

Information in a gene directs the production of a cellular product.

Entire "Library" of genetic instructions that an organism inherits.

Researchers who study whole sets of genes of a species as well as comparing genomes between species.

Use of computational tools to store, organanize, and analyze the huge volume of data that result from high-throughput methods.

In which accumulation of an end product of a process slows that process.

In which an end product speeds up its own production.

Are the most diverse and widespread prokaryotes and are now classified into multiple kingdoms.

Live in extreme enviroments, such as salty lakes and boiling hot springs.

All of the Eukaryotes, like Plantae, Fungi, and Animalia.

Because the natural environment "selects" for the propagation of certain traits among naturally occurring variant traits in the population.

Meaning "to know", is a way of knowing an approach to understanding the natural world.

A search for information and explananation, often focusing on specific questions.

Recorded Observations.

Collecting and analyzing observatins can lead to importand conclusions based on a type of logic.

Is a tentative answer to a wellfframed question-and explanation on trail.

Is generally used after the hypothesis has been develped and involves logic that flows in the opposite direction, from the general to the specific.

One that is designed to compare an experimental group with a control group.

Much broader in scope than a hypothesis. They are usually supported by great deal of evidence.

A species that is easy to grow in the lab and lends itself particularly well to the questions being investigated.

Generally applies scientific knowledge for some specific purpose.
