Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptations. this phenomenon is known as natural selection. in order for natural selection to occur, a. one population must become extinct so another can be created. b. there must be more male organisms than female organisms. c. all of the organisms within a population must be exactly the same. d. organisms within a population must have some genetic variation.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
