  • structure of DNA (1950s) - Rosalind Franklin
35
Q

What is the Inductive Method (described by Francis Bacon)?

A
  • make numerous observations until confident in making generalizations & predictions
  • knowledge of anatomy obtained this way
36
Q

What is the Hypothetico-Deductive Method?

A
  • ask question based on observations
  • formulate ______________— educated speculation or possible answer to question; “if–then” prediction
  • knowledge of physiology gained this way
37
Q

What are important components of a sound experimental design?

A
  • Sample size
  • Controls
  • Double-blind method with placebo
  • Peer review
38
Q

What were Darwin’s observations?

1) Individuals ____________ (w/in a population)
2) Offspring resemble _____________________
3) All species produce ________ _______________ offspring
4) Resources are __________________
5) Populations do not expand ______________________

A

1) Individuals VARY (w/in a population)
2) Offspring resemble PARENTS
3) All species produce TOO MANY offspring
4) Resources are LIMITED
5) Populations do not expand INDEFINITELY

39
Q

Evolution occurs in ___________________, not individuals

A

Evolution occurs in POPULATIONS, not individuals

40
Q

What is Natural selection?

A

some individuals w/in species have hereditary advantage over their competitors

41
Q

What is adaptions?

A

physical feature that gives advantage

42
Q

What are primates?

A

Order of mammals to which humans, monkeys, and apes belong

43
Q

What is vestigial?

A

anything we have that’s either not functional or that we can live without (wisdom teeth, tail bone, appendix)

44
Q

What is bipedalism?

A

standing and walking on two legs

45
Q

How did Bipedalism emerge and what were it’s effects?

A

in Africa - became hotter and drier, much of forest replaced by savanna (grasslands) = more predators and less protection - started standing on their hind legs to look around for danger, in turn, helped them stay alert and free up forelimbs for purposes other than walking (holding things for example)

46
Q

What is the hierarchy of complexity?

A

things are built on top of each other

47
Q

What is the order of the hierarchy of complexity/the human structure?

A
  • Organism is composed of organ systems
  • Organ systems composed of organs
  • Organs composed of tissues
  • Tissues composed of cells
  • Cells composed of organelles
  • Organelles composed of molecules
  • Molecules composed of atoms
48
Q

Reductionism—theory that a large, complex system (e.g. human body) can be understood by studying its ___________ components

A

Reductionism—theory that a large, complex system (e.g. human body) can be understood by studying its SIMPLER components

49
Q

Holism—there are “emergent properties” of whole organism that cannot be predicted from properties of separate parts

Humans are more than the _______________________.

A

Holism—there are “emergent properties” of whole organism that cannot be predicted from properties of separate parts

Humans are more than the SUM OF THEIR PARTS

50
Q

What is atomical variation?

A
  • No two humans are exactly alike
  • variation in organ locations / formations
51
Q

What are the 3 types of anatomical variations?

A

situs solitus, situs inversus, situs perversus

52
Q

What is situs solitus?

A

“normal state” ex) always 1 heart

53
Q

What is situs inversus?

A

that in some people, everything is switched

54
Q

What is situs situs perversus?

A

things in wrong spot - functional, just not “normal”

55
Q

What are the characteristics of life?

A

DRE RHOCUM

D - development - living things can change

R- reproduction - living things capable of producing living things

E- evolution - group of living things

R-responsiveness and movement - react to environment (move when ball thrown at you)

H- homeostasis - maintenance of stable internal condition

O- organization -things are in a certain place (heart, lungs)

C- cellular composition - all living things made up of cells

M-metabolism- bring in food to break down and release into energy used to power cellular movement

56
Q
A
57
Q

Homeostasis is the maintenance of _________________ through detection of change & activation of mechanism to oppose it

A
  • Homeostasis is the maintenance of RELATIVELY STABLE CONDITIONS through detection of change & activation of mechanism to oppose it
  • state of body fluctuates (dynamic equilibrium) w/in limited range around set point
  • self-restoration
  • loss of homeostatic control = illness or death
58
Q

Homeostasis is maintained by….

A

negative feedback

variance invokes mechanism to return

59
Q

What are 2 types of negative feedback?

A
  1. vasoconstrictor - blood vessels get smaller in order to preserve heat (first mechanism employed to maintain body temp)
  2. vasodilation- enlarging diameter of blood vessels to let heat out
60
Q

What are the 3 processes of negative feedback?

A
  1. receptor - detects change (ex, low blood pressure)
  2. integration center - figures out what needs to be done (ex, tells brains)
  3. effector - carries out what needs to be done (ex, tells heart to increase heart rate to bring blood pressure up)
61
Q

What doesn’t bring you back to homeostasis and does it cause a rapid or slow change?

A

positive feedback - causes rapid change

62
Q

What is the self-amplifying cycle?

A
  • leads to greater change in SAME direction
  • change produces more change
63
Q

What are some normal ways of producing rapid changes?

A

childbirth, blood clotting, fever

64
Q

What happens when you have a fever > 104°F?

A
  • metabolic rate increases
  • body produces heat even faster
  • body temperature continues to rise
  • further increasing metabolic rate
  • cycle continues to reinforce itself
  • becomes fatal at 113°F
65
