A defining characteristic of sympatric speciation is Group of answer choices a. The appearance of new species in the midst of old ones b. Asexually reproducing populations c. Geographic isolation. d. Artificial selection e. Large populations

a. The appearance of new species in the midst of old ones

Explanation:

The process or mechanism by which the formation of the new species takes place is called speciation. On the basis of factors and conditions, there are many ways in which the speciation takes place. Such type of speciation in which the new species are formed in the presence of the old species and both can easily survive in the same geographical condition or environment is known as sympatric speciation. The main cause of this speciation is the polyploidy condition.

Humid continental climate is found in the interior of continents between the 30 and 60 degrees latitude, but usually above the 40 degree line.   40 degrees north of the equator means less direct sunlight and therefore less warmth.   this climate is mainly found in the northern hemisphere since there are no major landmasses in the southern hemisphere.  if you live in northern indiana, you know all about humid continental because that is the climate type you have!

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
