Exam (elaborations) Honors Biology

Biology️️the scientific study of life What is the fundamental property of ecosystems?️️interactions between the (living and nonliving)things in them Life's hierarchy of organization️️Biosphere > Ecosystem > Community > Population > Organism > Organ System > Organ > Tissue > Cell > Organelle > Molecule Ecosystem️️all the organisms living in a particular area, as well as all the nonliving, physical components of the environment that affect the organisms (air, soil, water, sunlight, etc). Community️️a group of all the organisms living together and potentially interacting in a particular area Population️️a group of organisms of the same species living in the same area at the same time, and which are capable of interbreeding. Organism️️one individual living thing Organ System️️a group of organs working together to perform vital body functions Organ️️a collection of tissues that carry out a specialized function of the body Tissue️️a group of similar cells that perform the same function. Cell️️basic unit of life Organelle️️a tiny cell structure that carries out a specific function within the cell Cell Membrane️️an organelle that separates a cell from its environment Molecule️️the simplest structural unit of an element or compound DNA️️(a molecule) deoxyribonucleic acid Science️️Derived from a Latin verb meaning "to know". An organized way of gathering and analyzing evidence about the natural world. Two main scientific approaches️️1. Discovery Science 2. Hypothesis-Driven Science Discovery science️️The study of structures and processes that we can observe and measure directly/indirectly with the help of tools. Hypothesis-Driven Science️️Observations of discovery science = ask questions/seek explanations Hypothesis️️usually an educated guess, a tentative answer t
