As the human population spread out of Africa into new regions, genetic diversity Group of answer choices went up as an adaptatio
n to new environments. went down because each expansion had a chance of leaving behind one or more genetic variants. maintained an equilibrium because population density stayed the same while territory expanded. varies randomly, do some populations has greatly increased variation while some had greatly decreased variation.
Genetic diversity decreased as the human population migrated from Africa to other continents because each migration had a chance to obliterate one or more genetic variants.
<h3>What is genetic diversity?</h3>
The term "genetic diversity" refers to the entire gene pool that a population or species possesses in a specific habitat.
During migration, genetic diversity is essential for adjusting to new environmental situations.
The genetic diversity decreased when the human population migrated from Africa to other continents since each migration had a chance of bringing with it one or more genetic variants.

As the human population spread out of Africa into new regions, genetic diversity went down due each expansion had a chance of leaving behind one or more genetic variants.
<h3>What is genetic diversity?</h3>
Genetic diversity makes reference to all gene pool that a population and/or species exhibit in a given environment.
Genetic diversity is fundamental to adapt new environmental conditions during migration.
In conclusion, as the human population spread out of Africa into new regions, genetic diversity went down because each expansion had a chance of leaving behind one or more genetic variants.
Pollen tubes are produced by the male gametophytes of seed plants. Pollen tubes act as conduits to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.
After looking at the diagram of organism, the sequence that will best represent the food chain within this particular food web is sedges-ants-frogs-kookaburras. So the correct answer choice will be number 2.
Foresters are responsible for determining areas that can be harvested sustainably and helps monitor areas to be harvested. Foresters determine which areas have trees that can be removed without causing harm to the environment and ensures that areas are not overharvested.
