Acid Rain is the problem threatening many of Europe's (most specifically Germany's) forests, lakes, and rivers. Acid rain travels via the wind and the acid pollutants can travel through this said wind to multiple countries. It was a large problem in the 1970's and 80's.
Answer:
Myrmecophytes, otherwise known as ant-plants, share a mutualistic relationship with a colony of ants. This is when two organisms of different species each benefit from the activity of the other. There are over 100 different genera of myrmecophytes that can be found across the world's tropical regions

Answer:
D-DNA molecule
Explanation:
The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.
The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.
The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>
A
Explanation:
The genome of prokaryotes has no introns hence their mRNA does not need splicing like in eukaryotic cells. Also, because the genome of prokaryotes is not delimited from the cytoplasm by a nuclear membrane, ribosomes can attach to the elongating mRNA during transcription and begin translation. Therefore translation of mRNA occurs concurrently with transcription which cannot happen with eukaryotic cells.
In the nucleus of eukaryotic cells, transcription results to a nascent mRNA which is spliced into a mature mRNA.The mature mRNA has to travel outside the nucleus to the cytoplasm to be translated by ribosomes.
