Life Science Final Flashcards
(51 cards)
Know the definitions for the following types of fossils AND examples of each:
Carbonized- formed when a buried organism decays leaving behind only a thin film of carbon
Mineralized- if an organism is buried by wet sediment, chemicals in the water can lech into the small spaces within an organism’s tissues the chemicals eventually harden eventually the tissues are hardened and replaced with an exact copy made of stone
Original material- a fossil may consist of all or part of the original organism not in a mold, cats, or mineralized fossil (ex amber)
Trace fossil- evidence that an organism leaves behind that isn’t part of the organism itself
Why do evolutionists and creationists view the history of change in living things differently? They start off with different beliefs about the story of the world
They start off with different beliefs about the story of the world
Which method of rock dating can be used only for “young” fossils?
Carbon-14
Because a whale’s flipper and a bat’s wing have similar bone structure evolutionists refer to the body parts as
Homologous Structures
What are the problems with the methods of dating rocks?
It depends on certain things being true that we may not be able to prove true you have to assume that the way things happened a long time ago happened at the same rates today
What is the main problem for evolutionists attempting to use homologous structures to prove ancestry?
It proves that it is based on assumptions they assume that if some animals did have a common ancestor there is no way to confirm the assumption
How do creationists view mutations?
That they helped the organism survive and reproduce
What does the theory of natural selection state?
The process through which organisms with certain adaptations survive to pass on their traits to a greater number of offspring than other organism do
What is the difference between created “kinds” and different “species”? Do they refer to the same groups of organisms?
A kind is a distinct group of organisms that God created to reproduce species are different groups of a kind… For instance a horse and a donkey can breed because they are the same kind only a different species but a horse and a cow can’t breed because they are a different kind
How are humans different from other organisms?
They are made in the image of God and have a soul as well as intelligence
Which type of tissue lines the external and internal surfaces of your body?
Epithelial
The human skeleton would best be described as ________________. (organ, tissue, or organ system?)
Organ System
The thick layer of skin that contains many blood vessels nerves, and hair follicles is the
Dermis
The pigment that is responsible for much of the color of human skin is
Melanin
Do skeletal muscles work in pairs?
Yes
What are tissues?
A group of cells that work together
What are organs? A group of tissues that work together
A group of tissues that work together
Do voluntary muscles move the body by pushing on the bones
pulling them
What do muscles do when they lack oxygen?
Lactic acid fermentation
Different ethnic groups likely developed after
The tower of Babel
What is found in the central cavity of many bones?
spongy bones
The elbow is an example of a(n) ___________________ joint.
movable
The connective tissues that connect muscles to bones are called
tendons
Biceps and triceps are examples of ________________ muscle.
voluntary striated
