Quiz 4 Flashcards
Mitochondrial transfers
children with three parents
In Vitro Genetogenesis (IVG)
from skin cell to sex cell
solo IVG is possible in theory
ovarian transplants
removes ovaries and freezes them then implant for live birth
Chimeras
Creating human organs in animals
life span
defined only the time between birth and death
USED to be the best
worried about time, clocking into life and clocking out
health span
determines the quality of life
can be dependent upon education, access to health care, emotional connections, lifestyle choices and place of residence
BECOMING the best indicator of public health
not how many years but what you get out of those years
Education and health span
best educated Americans live 10-14 years longer than the least educated
the well educated have higher incomes, smoke less, follow doctors instructions, less likely to be overweight, college graduates are more likely to marry and stay married, married people suffer fewer heart attacks and strokes
catalyst
individuals, war, economic opportunities
catalysts are moving us toward “health span” mentality
palliative care
specialized medical care for people with serious illness
focus on providing relief from the symptoms and stress of a serious illness
the goal is to improve quality of life for both the patient and the family
foundations of global communication
triangulation, trilateration
triangulation
finding a position using triangles with known points (like a cell phone tower)
trilateration
finding a position from three distances.
it centers around finding your position on earth by knowing the location of orbiting GPS satellites and the distance from those satellites to your location on the planet
important program that led to space exploration
space shuttle program
newton’s first law
states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force
orbital velocity
the velocity given to the body to keep it in orbit. This velocity is usually given to the artificial satellite so that it revolves round any particular planet
orbit paths
orbits are not freeways (360 degrees, size and shape can be adjusted)
objects at different heights move at different speeds in orbit
space station is 200 miles above earth and moves about 17,500 mph
types of orbits
polar orbit, geostationary orbit, circular orbit, elliptical orbit
polar orbit
go up and over the poles
allows satellite to go around as the earth rotates looking for climate patterns
geostationary orbit
a circular orbit 22,236 miles above the Earth’s equator and follows the direction of the earth’s rotation
orbital period is equal to earth’s rotational period, stays fixed in the sky
key point is line of sight
line of sight
global communication doesn’t happen without the line of sight between satellites
circular orbit
the orbit with a fixed distance around the barycenter, that is, in the shape of a circle
elliptical orbit
gets really close to earth for short time and then goes far away
