The area present in between south pole and north pole has been said that it has been extremely cold and the area present near the equator has extremely hot.
The area of north pole has not the part of any country or the north pole does not lie in any country. The main reason of the coldness of the north pole and south pole has that they do not receive any direct sunlight. The best time to visit the north pole has the time of June and July because in this month the ice of the north pole is thinner as compared to other months.
Therefore, Wegener is not qualified to propose theories in the fields of geology and the history of the Earth because there was no mechanism available to endorse his proposals and offer a convincing and truthful explanation, hence the rejection of the Continental Drift, the theory that made him famous.

What is DNA?DNA stands for deoxyribonucleic acid.
DNA is defined as a collection of molecules that are in charge of transporting and passing genetic information from parents to children.
It can also be defined as a sophisticated molecule that carries all the data required to create and maintain a creature.
There are basically two types of DNA.
Autosomal DNAMitochondrial DNAToday, DNA serves three unique purposes: genetic, immunological, and structural, all of which depend in different ways on the sugar phosphate backbone and the bases.
Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.
Thus, DNA is created by the DNA polymerase and unzipped by the DNA helicase.

Based on the MSW streams that you researched above (Salem, Wake County, and USA), what would be the most meaningful strategy to implement in an effort to reduce the waste streams. This is purposely left ambiguous to allow for you to creatively answer the question.
Answer:
Remove organic waste, Reduce packaging, eliminate bottled water, give food waste to animals.
Explanation:
Organic waste, Reduce packaging, eliminate bottled water, give food waste to animals are the some strategies to reduce the waste streams. The Organic waste in the water streams can be used as a fertilizer to the plants. The portion of Organic waste is large in the waste stream so its removal is good for the reduction in waste stream as well as for the crops. Avoid throwing packages and bottles in the waste water and reuse these packages and bottles through recycling process. Food waste that are thrown in the waste water can be used as feed to animals because there is a lot of nutrients present in it.
