Earth History
the variety of species on Earth
biodiversity
Shows what organisms were once living on earth. Shows how organisms evolved.
What does the fossil record tell us about how life has changed over time?
is found in chromosomes.
DNA
known as ‘father of Genetics’
Gregor Mendel
A change in the nucleotide sequence of the DNA
Mutation
data, or information, that either supports or counters a scientific theory or idea
scientific evidence
Mass extinctions, organisms slightly changing over time, appearance of new organisms
What major changes have occurred in the fossil record over time?
is the science of heredity.
Genetics
is the process by which characters are passed on from parent to progeny. It is the basis of heredity.
Inheritance
Chromosomal mutations
Inversion, translocation, duplication, deletion
a well-tested explanation of scientific observations and experiments that is supported by a large amount of evidence
scientific theory
It tells us that the land used to be underwater- uplift moved the land up.
What does finding Marine Fossils on the summit of a mountain tell us?
are expressed if 2 copies are present.
Recessive are expressed if 2 copies are present.
arise due to Reshuffling of gene/chromosomes, crossing over or recombination, mutation and effect of environment.
Variation
The most common genetic disorder
Cystic Fibrosis
a description of a natural phenomenon that has been repeatedly tested and appears to be without exception
scientific law
the process of determining the approximate age of a rock, fossil, or event
absolute dating-
is the observable traits determined by the genotype.
Phenotype
Conducted Hybridization experiments on garden pea plants
Mendel's law of inheritance
Red blood cells have an abnormal sickle shape
Sickle Cell Anemia
a representation of an object or process that makes important aspects easier to observe
model
the process of determining whether one rock, fossil, or event is older or younger than another
relative dating
are found in the nucleus of a cell and come in pairs.
Chromosomes
It is the basis of heredity.
Inhertance
Also known as trisomy 21
Down Syndrome
