What is the difference between Abiotic and Biotic?
What is abiotic is a non-living factor (like the Earth's atmosphere), while biotic is a living factor (like plants growing)
100
What is Natural Selection?
What is the theory that species with the best variations over time will be better adapted to their environment
100
What is a fossil?
What is the remains or traces of organisms that once lived on Earth
100
Do individuals in a species evolve?
What is no, populations as a whole do
200
Extinct
What is the process of a population dying over time and no longer existing
200
In what order is a timeline of abiotic and biotic factors written?
What is from most recent down to oldest
200
Who came up with the theory of Natural Selection?
What is Darwin
200
Would the oldest rock layer be on the bottom or the top?
What is the bottom
200
What is the difference between inherited characteristics and acquired characteristics?
What is inherited characteristics are traits that an organisms gets from its parents, while acquired characteristics are traits that an organisms gets over time
300
Isotopes
What is atoms of an element that vary in the number of neutrons they have
300
True or False: There are more abiotic events than biotic ones
What is false
300
What are the 4 main parts to Natural Selection?
What is variation, adaptation, selection, and genetic change over time
300
What do scientists use to help them date the fossils?
What is radiometric dating and geologic records
300
Why do some species become extinct?
What is some species with the better variations to survive continue to grow and reproduce, while the ones without those variations can't survive and eventually die off
400
Half-Life
What is a measurement of how long it takes for radioactive decay to occur
400
What was the first biotic event in Earth's history?
What is the beginning of life on Earth (bacteria and prokaryotes)
400
How do characteristics of a species affect the population size?
What is the ones with the best characteristics suited to their environment live, while the ones who don't slowly die off and adapt
400
This provides evidence that fossils and rock layers have different ages
What is radiometric dating
400
Why are humans so similar to chimpanzees?
What is humans adapted from chimpanzees over time to become a whole different species which is why we both have some of the same traits such as opposable thumbs
500
Radioactive Decay
What is the process of unstable atoms (like radioactive isotopes) breaking down to form more stable isotopes
500
How do abiotic events affect biotic events?
What is with more abiotic things (atmosphere, land, oxygen), more biotic events (first known plants, adaptation of plants to land, multicellular life) can happen over time
500
What will happen to a population of birds with small beaks living in a desert with food deep in the ground?
What is the birds will have to adapt to growing longer beaks so they will survive and be able to get the food that's buried deep in the ground
500
How are fossils made?
What is the organisms that once lived get stuck in the new rock layers and their shapes get imprinted into the rocks
500
What are the 5 types of evidence for evolutionary relationships?
What is anatomical evidence, vestigial structures, embryological likeness, fossil records, biochemical likeness, and DNA analysis
