Answer:

How can we explain why there is so much diversity of life on Earth today?

There are several key reasons for high biodiversity in tropical ecosystems. High NPP directly contributes to α-diversity by supporting more species with minimum viable populations, whereas enlarged populations of each organism increase overall mutation frequency and hence intraspecific genetic variation.

Which of the following is a radical?<br><br><br> O<br><br><br> OH<br><br><br> H 2 O<br><br><br> H
Olegator [25]

The radical in this question is OH.


The reason this will be a radical, is that the definition of a radical is the presence of an unpaired electron. This causes the radical to be unstable, desperately wanting to do something with the free electron that it has.


Oxygen has a charge of 2-, and Hydrogen has a charge of +1. When you pair them, you end up with a net charge of 1-, which is the presence of that unpaired electron. It will usually be written as: OH^{-}

Translation
sertanlavr [38]

A- growing polypeptide       B- Lone amino acid

C-  tRNA                                      D- Anticodon

E- mRNA                                F- Small ribosomal subunit

G- codon                             H- Large ribosomal subunit

Explanation:

Methionine (start codon) , leucine, methionine, arginine, aspartic acid, glycine, glycine, leucine, histidine, stop codon

Three types of RNA that takes part in the translation are:

mRNA: It is formed by the process of transcription. The DNA strand is copied as mRNA with help of RNA Polymerase. The mRNA strand is single- stranded and consists of codons which code for amino acids for the protein synthesis. Not full sequence of mRNA codes for amino acid chain there are non-coding regions called introns which are removed during splicing and only exons code for the amino acid sequences.

tRNA: It brings the correct amino acid to the growing polypeptide chain by reading the codons from the mRNA. It has anticodon which helps in bringing the correct amino acid coding to mRNA sequence.

rRNA: rRna plus protein and ribosome makes up rRNA. The ribosomes are called protein factory,  because growing polypeptide chain is formed here. They are responsible for reading the correct amino acid bonding to form polypeptide. They are having two subunits smaller and bigger depending on their sedimentation rate by centrifugation.

In eukaryote,s protein synthesis occurs in the ribosomes which are present in the cytoplasm of the cell.

B. All the three nucleotides that code for amino acid are important because any base difference in amino acid will change the protein formed due to amino acid difference.

oksano4ka [1.4K]

Answer:

When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body.
