what is an adaptation?
a change or the process of change by which an organism or species becomes better suited to its environment.
what is artificial selection?
the selective breeding of a plant or animal to produce an offspring with traits valuable to humans. Or when human choose the traits and breed organisms for those traits.
what is absolute age?
absolute age is the most accurate age of dating and is also called radiometric dating.It uses the decay of radioactive elements to find the absolute age of rock or fossil.
what is a chromosome?
thread-like structure formed from DNA and proteins.
How are dominant traits represented?
DD
what is natural selection?
the process through which populations of living organisms adapt and change.
what is cloning?
the process of producing individuals with identical or virtually identical DNA either naturally or or artificially.
what is relative dating?
relative dating tells scientist if a rock layer is older or younger than another.
what is the difference between mitosis and meiosis?
mitosis is the division of cells and meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes.
What is it called when a parent carries two same forms of a trait aa or AA.
Homozygous.
what is genetic drift?
the process through which populations of living organisms adapt and change.
what is natural selection?
nature selects and favors traits more suitable for their particular environment.
what is the law of superposition?
geologist assume that the newest rock layers are on top of the older ones unless some type of disturbance has occurred.
how many cells do mitosis and meiosis produce?
Mitosis produces two identical diploid daughter cells, while meiosis produces four genetically unique haploid cells.
