Industrial melanism<span> is the resultant effect of</span><span> </span>industrial pollution on arthropods<span>. The individuals that had a darker pigmentation were more fit to the new environment, more polluted that caused darkened buildings and trees, and were thus favoured by </span>natural selection to survive.
Insecticide resistance and antibiotic resistance is also a manifestation of the emergence of new groups of organisms that are resistant to a specific attack out of an existing population, and are therefore favoured by selection to survive over the others.

Dafna11 [192]

Ionic bonding involves electrostatic interactions between oppositely charged ions, and can significantly enhance the binding strength of biomolecules immobilized to materials.

A chemical link known as an ionic bond occurs when an electron is transferred from one atom to another. Ionic bonding requires the presence of an electron acceptor and an electron donor, which is frequently a metal (often a nonmetal). Electrovalence is the process of moving electrons. A positive ion, also known as a cation, is created when an atom loses one or more electrons. The other atom that picks up one or more electrons will change into a negative ion known as an anion. The elemental name is modified by adding a -ide at the end to designate the ion that accepts the electron. For instance, the name of the anion of chlorine is chloride while the anion of sulfur is sulfide.

You are excited because your lab is studying the first microorganisms retrieved from Mars! Interestingly, their genetic material
Oliga [24]

Answer: The maximum number of amino acids that could be coded is 2

Explanation:

  • A codon in this microorganism is 2 bases instead of 3 bases .
  • In order to encode a protein a sequence requires a start and stop codon
  • If you assume no start codon: then only 2 bases would make up the stop codon.
  • This leaves 4 bases which is 2 codons. This would encode 2 amino acids.

  • If you assume a start and stop codon, then each codon would be allocated 2 base pairs each =  4 base pairs
  • This only leaves 2 base pairs, a single codon which would only code for 1 amino acid
