How does the sahara desert act like a barrier between North Africa and sub-saharan Africa.

Geography
1 answer:
GuDViN [60]4 years ago
8 0

Answer:

It is difficult to cross.

Explanation:

The Sahara desert is a vast region about the size of the continental United States that is extremely dry and barren. The lack of water resources in the desert make the land unsuitable for agriculture and human population.

As a result, the Sahara acts as a giant natural wall both economically, culturally, and socially since relations between states to the north and south of the desert are difficult.

  • <u>The northern parts are closer to the baltic plains and the mainland of the Greenlands as the entire region climate is mostly impacted by the gulf stream and that brings the cool and cold subarctic and arctic type of climate.  And the presence of the boreal forests that are also found in the tundra region. </u>
  • While that of the eastern coasts of the U.S have a temperate type of climate and the warm summer, cold and snowy winters and mild winters in the southern parts.

Between New Year's and Memorial Day, at middle latitudes in the Northern Hemisphere, the length of the day
otez555 [7]

Between New Year's and Memorial Day, at middle latitudes in the Northern Hemisphere, the length of the day increases.

The northern hemisphere is the part of the planet that lies north of the equator. It accounts for about 90% of the world's population and most of the world's land. All of North America and Europe are in the Northern Hemisphere. Most of Asia, her two-thirds of his in Africa, and her ten percent in South America are also in this hemisphere.

This is because the hypothetical axis of the Earth does not move straight up and down, it is tilted 23.5 degrees. The movement of the Earth around this axis causes changes between day and night. During the Northern Hemisphere summer, daylight hours increase as you travel north.

In a study of genetic variation of the Graceland gene, a researcher finds that there are two alleles in a population. In a large
alekssr [168]

Answer:

No, <u>Hardy Weinberg Equilibrium is a theory that states the allele and genotype frequencies in a population will remain constant irrespective of the sexs.</u>

Explanation:

  • Derivations from the HWE Hardy Weinberg Equilibrium assume that organisms are diploid, population size is infinite, and mating is random.
  • In all the equilibrium the four fundamental factors like the selection, mutation, random mating including interbreeding and small population size. So, if the number of heterozygotes is 34 then the significant level is 0.067.
  • So higher the significance level higher is the heterozygotes. In the absence of selection and genetic drift, all the frequencies within variables are constant. This principle was named by G, H Hardy.
