Many reasons to be honest but the main one is because of erosion and the water levels (rising and falling)
Answer:
Through mRNA
Explanation:
DNA is the genetic material of most living cells and it holds the information needed for the synthesis of functional products (proteins). This information is embedded in the nuceleotide sequence of the DNA and it needs to be expressed through the processes of transcription and translation. The process of transcription occurs in the nucleus of eukaryotes where the genetic material (DNA) is located.
Transcription involves the copying of the information contained in the DNA into a carrier molecule known as messenger RNA. The messenger RNA (mRNA) is not used for long term storage unlike the DNA, it helps convey the information in the sequence out of the nucleus into the cytoplasm, where it attaches to Ribosomes (site of protein synthesis) for translation to occur. The mRNA contains complementary nucleotide sequence of the DNA.
Answer:
Filtration
Explanation:
Filtration is the process that reduces the microbes from a solution which consists of heat-sensitive substances. It is also used to produce sterilized solutions. Filtration is a process that physically removes the microbial population from the sample with the help of filters.
For example, the depth filters remove the microbes from the solution by trapping them to the filter material. Likewise, membrane filters are the porous membranes that are used to remove the vegetative cells of most of the microbes.
