Which of the following is true about geologic time? It is extremely easy to model
We have a complete understanding of all geologic time
periods
It is extremely difficult to model because it covers so much
time
HELPL

The geologic time scale is the calendar for events in Earth history. It subdivides all time into named units of abstract time called escending order of duration eons, eras, periods, epochs, and ages.

The correct option is A. If a dominant allele is present, the recessive allele won’t be seen.

The dominant allele is the one which appear, and the recessive one isn't shown.

For example - If a person has 2 alleles of eye colour as B ( black ) and b ( brown ), in which black is dominant and the brown one is recessive, then the person will have black eye colour because only dominant allele shows its characteristics.
