Notes for Biology yay

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Introd­uction

Biology
study of life
Cell
Basic unit of life
 
differ­ent­iates living and nonliving things

Charac­ter­istics of Life

charac­ter­istics that define living things
Organi­zation
emergent proper­tie­s-c­omp­onents group together to form new f(x)
 
atoms>­mol­ecu­les­>or­gan­ell­es>­cel­ls>­tis­sue­s>o­rga­ns>­organ system­>or­gan­ism­>po­pul­ati­on>­com­mun­ity­>ec­osy­ste­m>b­ios­phere
Energy Utiliz­ation
metabo­lism: absorbs energy + converts to bodily f(x)
 
energy transfer lost through heat
 
classified based on source of energy
 
1. Primary Producers (autot­rophs
-obtain from non-living
 
2. consumers
-from living
 
3. decomp­osers
-from unliving
Homeos­tasis
cells keep conditions within certain range
 
responds to stimuli to counteract changes
Reprod­uction
goal of life:
-keep genes alive
   
-transmit DNA
   
-pass traits to genera­tions
 
2 ways
 
1. Asexual
-1 parent. all offspring identical to parent
 
2. Sexual
-2 parents. genetic diversity
Growth Develo­pment
Growth
-increase in complexity of cells
 
Develo­pment
-inc in complexity of f(x) of cells
 
Species:
specific pattern for growth and dev
Response to Enviro­nment
Irritable:
can respond to stimuli (senses as receptor)
 
stimul­us-­eff­ector train:
stimul­us-­>re­cep­tor­->c­oor­din­ato­r->­eff­ect­or/­res­ponse
Evolut­ionary Adaptation
Adapta­tions:
inherited charac­ter­istics to suit enviro­nment
 
Evolution:
change in genetic makeup of population over genera­tions
   
Charles Darwin & Alfred Russel Wallace (conce­ptu­alized)
 
Natural Selection:
enviro­nmental pressure
 
Exposure to prolonged stimuli induces natural selection
Def of Life
NASA
-"se­lf-­sus­taining organism with chemical systems that are capable of Darwinian Evolut­ion­"
 
life is too complex, diverse, and dynamic to be given an exact definition
 

Bioethics

study of ethical, social, and legal issues that arise in the biomedical field
intends to 'guide', like a handbook
Autonomy
determine wishes of the patient
 
ppl make choices based on own moral values and beliefs
 
Principle of self-rule and principle of respect for persons
 
informed consent: aware of every single option available to them
 
informed consent requir­ements
 
1. for patient
capable of unders­tanding conseq­uences of consent
   
capable of making sound decision
 
2. for healthcare provider
provide all necessary info for patient
   
perform reflective convo with patient
Benefi­cience
promote good
 
obligation to do something that will most likely do good unless there is sufficient reason not to
Non-Ma­lef­icience
not to inflict harm
 
obligation to not perform act that will most likely do harm
 
>fu­nda­mental duty of med service providers:
give quality health care to all patients
 
>ac­kno­wledge that :
1. there are limits to ppl's abilities
   
2. treatment options may be too complex
   
3. always a chance for benefit or the risk of harm
Justice
treat patients equally regardless of any other factors
 
medical need criteria:
 
1. likely benefit to patient
 
2. urgency of need to patient
 
3. change of quality of life to patient
 
4. duration of benefit to patient
 
conditions for determ­ining priorities
 
 
1. on a national level
cost of med goods
   
-fair and livable
   
-econo­mically stable
 
2. on an instit­utional level
model of medical triage
   
-to maximize number of survivors
