early study of everlution
How do species help scientists group organisms
providing a standardized, fundamental unit for classifying biodiversity based on shared evolutionary history, physical traits, and genetic makeup.
what is natural selcetion
a process by which individuals that are adated to their envorionment
what is fitness
staying healthy and being strong
What does it mean to go extinct
species, family, or group of organisms has completely died out, leaving no living members anywhere on the planet
What is a protein
Large, complex molecules essential for the structure, function, and regulation of the body's tissues and organs.
What might be hypothesized
predicting that lower temperatures reduce bacterial growth or that a specific medication modulates inflammatio
What is DNA
heredity material inside of all organsisms
what is a gene flow
the transfer of genetic material such as alleles or genes from one population to another
Why is a sudden change in the environment more likely to cause species to go extinct rather than to cause new species to develope
evolutionary adaptation is a slow process that cannot keep pace with rapid shifts
What is the endsymboisi
a biological relationship where one organism lives entirely inside another organism.
what is a fossil
the preserved remains, imprint, or trace of any once-living organism from a past geological age.
How many chromosomes does the human have
46
What is a Genetic drift
the random change in the frequency of gene variants (alleles) within a population over time
what are fossli fuels
natural, carbon-rich energy sources formed in the Earth's crust from the ancient, fossilized remains of prehistoric plants and animals
What is trasfer
the trasfer of genes can happen when one cell engulfs another or when baterica share there DNA with other cells
adaption
an inhearitence behavior or physical chareicteristics
what i a Phenotype
the observable physical characteristics or traits of an organism
What is male competition
The struggle between males for mating access to females is a key driver of evolution, sexual selection, and the development of specialized traits.
how many chromosons does the femal have
42 chromosos
How do fossils form
When a deceased organism is rapidly buried by sediment.
What is a scientific theory
a well-tested explanation for a wide range of observatories and experimental results
What is a genotype
The complete set of genetic material carried by an individual organism.
is sexual selection a form of natural seletction
Yes,
how many chromoseons does the male have
46 chomosons
what is an organ system
a group of anatomical structures and organs that work together to perform one or more vital bodily functions
