Answer:
The two species concepts that are most likely to place dogs and wolves together into a single species are <u><em>biological and phylogenetic</em></u> concepts.
Explanation:
- The biological species concept establishes that a species is a group in a population whose individuals can mate and have viable, fertile descendence. These groups are also reproductively isolated from other groups or species. This is, the members of a species can not reproduce with the members of other species, or they can their progeny is unviable.
- The phylogenetic species concept refers to a species as the monophyletic group that is less inclusive for organisms. It is a group of organisms that share an ancestor in common and can distinguish from other similar groups. In this concept, a unique species can include a wide phenotypic variability.

Answer:
False. There are 20 amino acids, but 64 possible codons.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
• The end codons are UAA, UAG, UGA.
A chemical substance that an organism requires to live. a nutrient that is scarce or cycles slowly through an ecosystem. ensures that nutrients will be circulated throughout the biosphere.
Answer:
The Doctrine of Specific Nerve Energies has been and continues to be enormously influential in the physiology, psychology, and philosophy of perception. In simple terms, the Doctrine states that we directly perceive in the first instance the activity of our nerves, rather than properties in the external world.
