Introduction to Biology for Health Sciences Flashcards
biology came from what greek words?
bios; life and logus; to study
biology is also referred to as?
the science or the study of life
this deals with the origin, history, structure, function, classification, development, inheritance and significance of living things
biology
studied the human body and wrote a book about it called “the fabrica”; the father of modern anatomy
Andreas Vesalius
a physician who first recognized the full circulation of blood in our body
William Harvey
physician and biologist; studied the embryo of a chick
Marcello Malpighi
discovered the cell; piublished a book called micrographia
Robert Hooke
invented the microscope (over 500); father of microbiology
Anton van Leeuwenhoek
famous for their cell theory
Theodore Schwann, Matthias Schleiden & Rudolf Virchow (SSV)

cell theory (3)
- cells are the basic unit of life
- cells came from pre-existing cells
- all organisms are made up of cells
a counterhypothesis to spontaneous generation; this theory claims that life can only come from life.
biogenesis
it is the ability of an organism to maintain constant internal conditions; “steady state”
homeostasis
the process by which organisms change over time because of changes in heritable physical or behavioral traits.
evolution
It is considered the basic physical and functional unit of heredity. It is made up of DNA.
genes
refers to all the chemical and energy transformations that occur in cells as they carry out life’s processes.
metabolism
(building up the process)
anabolism
(breaking down the process).
catabolism
refers to an increase in size. It is accomplished through a complex series of chemical processes or intussusceptions.
growth
refers to the ability to react to any environmental change or stimulus that often results in movement.
irritability
living things must be able to produce other living things of their kind. it can be asexual or sexual.
reproduction and development
refers to modifications that promote the likelihood of survival. Living organisms that were not suited to new conditions either move to a better environment or change (evolution).
adaptation
parts of a living organism are arranged in a particular way
organization
what the are levels of biological organization?
biochemical, structural, physiological, and ecological organization.
the process in which living organisms integrate the nutrients from various external resources in their body and utilize them to satisfy the energy demands required to stay alive.
assimilation
All organisms belonging to the same species are alike with a certain degree of variations or differences, therefore we can say that living organisms have a what?
definite form and size
the driving forces for the development of science
curiosity and inquiry
One thing that is common to all forms of science
the goal “to know”
it is a suggested explanation for an event, which can be tested. It can also be called tentative explanations and can be generally produced within the context of a scientific theory.
hypothesis
is a generally accepted, thoroughly tested, and confirmed explanation for a set of observations or phenomena. It is also the foundation of scientific knowledge.
Scientific Theory
One of the most important aspects of the scientific method
testing the hypothesis/experiment
With this we can now accept or reject our hypotheses.
