Natural Selection
What are the two types of reproduction?
Sexual & asexual
The remains or impressions of a plant or animal embedded in rock or preserved.
Fossils
The Earth is estimated to be how many years old?
4.6 Billion
The process of all materials from a dead organism going back to nature to be used again.
Decomposition
A random error in the genetic code.
The process where more helpful (help them survive or reproduce more) traits become more and more common in a species, aka the most 'fit' survive.
Natural Selection
Looking at the layers of the rocks/soil is a method in what type of dating?
Relative
Order the 4 measurements on the Geological Time Scale from longest to shortest: Eras, Eons, Epochs, & Periods
Eons, Eras, Periods, & Epochs
What is the process called where a species changes over time?
Evolution
What is the proper name for the four bases; adenine, thymine, cytosine, and guanine?
Nucleotides
A trait that becomes more common because it helps the species survive and/or reproduce.
Adaptation
Name at least 3 different types of fossils.
Trace, Mold/cast, replacement, petrified, amber, & original material
True or False: The mass extinction that killed off the dinosaurs (Cretaceous-Paleogene, killed 76% of life on Earth) was the largest and the most recent mass extinction.
False, the Permian-Triassic Extinction was the largest (96% of all marine life, 75% of land life)
The layers of rocks are called...
Strata
During sexual reproduction, two gametes combine to form a...
Zygote
The biggest advantage to sexual reproduction, when there is a range of traits in a population.
Genetic variety/diversity
Fossils are formed when an organism dies and is trapped underneath layers of (sand, mud, etc.)....
Sediment
The record of Earth's history & development of life in chronological order.
What is the methods that determines the exact age of a rock by examining the amount of Carbon, a radioactive isotope, in it?
Absolute Dating
What is the sugar that works with phosphate to create the sides of the 'ladder' of DNA?
Deoxyribose
The first step in natural selection where way more offspring are produced than can survive.
Overproduction
A fossil of species who lived all over the world, but only for a short period of time.
Index Fossils
The _______ explosion represented the mass diversification of species on Earth due to the increase of Oxygen on the planet.
Cambrian
Relative Dating relies on this method of looking at the order of geological events in rock layers based on their relationship to other rock layers, aka older rock layers are found deeper in the ground.
Law of Superposition
This process uses enzymes like DNA helicase and DNA polymerase to copy DNA.
DNA Replication
