I'll try to explain, because I've had tubes before.  In fact, I still have them.

For me, tubes were put in because of too many ear infections, and excessive water in my ear.  The tube helped drain the water out.  You can see A picture I have in a file.  The tubes can be put I believe in the ear drum.  They're put there to help drain water that has trouble getting out on its own.

Why can the same trna and rrna molecules be used to synthesize a wide variety of polypeptides
Drupady [299]

Answer: The transcription and translation process allows trna and rrna molecules to be used to synthesize wide variety of polypeptides.

Explanation:

DNA molecule is made up of information for coding proteins. This information is passed on the mRNA during a process known as transcription. Transcription is the first of many steps of DNA based gene expression in which a part of the segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.

Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During the process of transcription, a DNA sequence is read by an RNA polymerase, which gives a complementary, antiparallel RNA strand referred to as a primary transcript.

A large diversity among genes is followed by a large amount of various mRNA molecules. However, the ribosomes consist of rRNA, which is included in the process of translation. Translation is the process whereby ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The overall process is called gene expression.

The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. It can be concluded that mRNA contribute to the diversity of polypeptide molecules due to the fact that it carries an information about their synthesis.

The concept of endosymbiosis (chloroplast & mitochondria) is widely accepted. What kind of relationship is it?
melamori03 [73]

Answer:

mutualistic

Explanation:

The interaction between two organisms in which both the organism gets benefitted from each other is called a mutualistic relationship. This mutualistic relationship is seen in the concept of endosymbiosis.

According to the endosymbiotic theory chloroplast and mitochondria are evolved by engulfment of different bacteria by ancestral cells. Then these bacterial remained in a mutualistic relationship with each other and the ancestral cell evolved into a eukaryotic cell.

So as mitochondria and chloroplast live with a symbiotic relationship with eukaryotic cells, therefore, it is considered as mutualistic relationship.
