Answer:

Genetic drift

Explanation:

Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.  

In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.

thousands of years

Explanation:

A delta the size of the Mississippi River will take several thousand of years to form because the process of formation of a delta is geologically controlled.

A delta is a place where  river enters or drains into the sea with many mouth or outlets.

Deltas are depositional terrain full of dis-tributaries.

  • For a delta to form, a terrain must be close to the mouth of an ocean or a larger body of water.
  • The entering stream must be large enough and have large amount of sediment.
  • The river mouth must have been cut to the same level with that of the drainage basin.
  • Most rivers such terrain should be at their lower course where they flow with very low velocity.
  • Wave action should be minimal along such coasts.

These processes takes several thousands of years if not millions.

Identify the Hindu beliefs. Only a priest can speak directly to God. The world is not real. It is an illusion that simply feels
emmainna [20.7K]

Answer:

The world is an illusion is the only possible answer.

Explanation:

Hindu priests do not claim to be able to spek to god, and since they are polythiestic they do not believe in one god. They do believe in a specific set of gods however so they would not believe that god is formless. They also believe in Karma and reinecarnation so ``We only live once`` would not be a viable answer either. To my knowlage ``The world is an illusion`` is not a core hindu belief either so I would question your teacher about that.
