Answer:
c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.
Explanation:
Darwin's theory was based on the evidence of natural selection and survival of the fittest.
Evidence of Darwin's theory were observed from the variation in the population which is supported by the environmental factor (natural selection) and these population than produce offspring, resulting in competition for survival within the population (survival for fittest).
Hence, the correct option is "c".
Answer:
Scientists usually use the potassium-argon method to date rocks that are older than about 1 million years. Uranium-238 is also used for radiometric dating. It has a half-life of 4.5 billion years. It decays to produce lead-206.
It comes down to genes it can be passed down from family
RELATIVE DATING is a way to estimate the order of geologic events by using rock layers, index fossils or other methods.
Relative dating is used by geologists to arrange geological events in sequential order. Relative dating usually use six principles to determine the relative age of any rock or fossil. The principles are: principle of superposition, principle of original horizontality, principle of lateral continuity, principle of cross cutting, principle of inclusions and principle of fossils succession.
Answer: Two main processes can cause less water to be excreted.- Less water intake Greater need for water in the body. This could include increased food consumption, especially foods containing salts that have to be diluted in the digestion process. Dietary fiber retains more water in the digestive tract until it is finally excreted. ^W^
