<span>a. they did not co-evolve with the natural species and lack natural controls, like predators</span>

The correct answer is option A

Invasive species can be defined the species that are introduced intentionally or unintentionally in an environment.

These species might adopt the environment in which they are placed or might not get involved in the environment.

Invasive species often unbalance in the ecosystem because they did not co-evolve and fit into the ecosystem as they are not controlled by the natural control like predators.

This creates ecological imbalance.

In prokaryotes, how does the length of a typical monocistronic mRNA compare to the length of the protein generated from this mRN
Nastasia [14]

1. The correct answer is: a. There are more mRNA bases than amino acids.

The transcription of monocistronic mRNA in prokaryotes is a rare process (it is more characteristic for the eukaryotes). Monocistronic mRNA is RNA, which encodes for only one or specific protein. Three bases of mRNA encode one amino acid of protein, thus it has more bases than amino acids of the final product, protein.  

2. The correct statements are:  

The mRNA contains 5' and 3' untranslated regions.

The stop codon does not code for an amino acid.

The start site of transcription is upstream of the start codon.

Each codon contains 3 RNA bases.

All of these approve that more bases are in mRNA since not all of them are translated into amin oacids.

Other statements are hallmarks of eukaryotic RNA processing, and therefore not relevant to prokaryotes.

The genetic code is said to be "degenerate" becauseA. A single tRNA may couple a single mRNA codon to multiple amino acids. B. A
Grace [21]

Answer:

The correct answer is option C. "A single tRNA specific for a particular amino acid may respond to multiple codons in an mRNA".

Explanation:

Genetic code is said to be "degenerate" because there are more codons than amino acids, which is possible because a single tRNA specific for a particular amino acid may respond to multiple codons in an mRNA. tRNA recognize the codons of the mRNA by a specific nucleotide sequence called anticodon, however the nucleotide sequence of the anticodon can recognize more than one codon sequence. This phenomenon takes place at the third position of the codon and is known as "wobble".
