The difference between the fertility rate and the death rate corresponds with the birth rate. When you take the number of children that have been born (alive) in a given year, and then minus the number of the people that have died in the same year, you get the birthrate. It can be positive, when there's more born children than people that died, or negative, when there's more people that died than born children.
Deflation is the process of erosion of dirt, rock, sand, or other sedimentary materials by the force of wind. When the wind blows through an area it creates deflation of the earths surface by moving particulate matter from one area to another.
Answer:
The answer is C. Sympatric Speciation via polyploidy
Explanation:
Among all various forms of speciation that exist, the most rapid is sympatric speciation which occurs when a population becomes separated in terms of reproductivity. The process of offsprings developing with more than the common number of chromosomes is referred to as sympatric speciation via polyploidy and it is this process that makes this speciation rapid.
Answer:
True, members of the Wampanoag tribe helped the colonists survive.
Explanation:
When the colonists first arrived in what is now Massachusets, they didn't really know what they're facing and were simply not aware of the conditions in the area and how to survive long term. This was a big problem because the reason why they moved there was because of searching for new opportunities and by not surviving this wouldn't have happened, while the government had its goal on long term settlements through which it will increase its influence in the region.
The reason why the colonists, referred to as Pilgrims, survived were the members of the native Americans, namely the Wampanoag. The Wampanoag were friendly and they explained to the colonists what they can expect climate-wise, thought them about the characteristics of the land, introduced them to local crops and how to grow them so that they can feed themselves. This led to good and friendly relations between the two groups and the colonists survived and managed to remain in the area.
