Answer:
This question lacks options, options are: a. Keystone species b. Dominant species c. Competitor species d. Omnivore species e. Mutualistic species. The correct answer is a.
Explanation:
The most connected species from a trophic point of view in an ecosystem are keystone species, since their elimination has great effects on the stability and persistence of the network. The Keystone species are those species that play a crucial role in the structure and dynamics of a certain ecosystem and that, in the event of their disappearance, would be seriously unbalanced. These species are responsible for the physical structure of the habitats of many other species, and they play an important role in the succession processes of ecosystems. Elephants play an important role in maintaining the structure and balance of ecosystems in these communities, therefore they are keystone species.

Answer:
Option A, the code is triplet
Explanation:
Complete question
When scientists were attempting to determine the structure of the genetic code, Crick and coworkers found that when three base additions or three base deletions occurred in a single gene, the wild-type phenotype was sometimes restored. These data supported the hypothesis that ________.
A) the code is triplet
B) the code contains internal punctuation
C) AUG is the initiating triplet
D) the code is overlapping
E) there are three amino acids per base
Solution
The team of Francis Crick was the first one to determine the length of the codon in 1961 by using a T4 bacteriophage. Through an assay, they devised the properties of genetic code and introduced frame shift mutation. So during the initial stage of experiment, only one single frame shift was introduced with in the viral protein of E. coli bacteria thereby making the protein nonfunctional. They then introduced an additional frame shift to restore the protein structure so that its function could be restored. This experiment was successful and concluded with a finding that genetic code is based on multiple of three bases
