Answer:
e. All of the above are considered species under at least one species concept.
Explanation:
All of the abovementioned conditions satisfy at least one condition of species definition. Further arguments are given below to support each statement,
a. A species is the <u>monophyletic group</u> of individuals who has a <u>common ancestor</u> which could be <u>distinguished from the closest phylogenetic relative</u> based on <u>conserved genes</u> (16S in bacteria and 18S in eukaryotes). In the statement above, beetles satisfy this condition.
b. A species is the group of individuals that are capable of <u>exchanging genes or can interbreed</u>. In the above statement, birds who are interbreeding with each other must be a single species.
c. A metapopulation is generically defined as the group of populations who are <u>separated by space</u> but are the <u>same species according to phylogenetic analysis</u>. Thus, the metapopulation of salamanders who are linked by gene flow (gene migration) should be treated as one species.
d. The word "<u>lineage</u>" already conveys the message that these bacteria belong share <u>sample place in the phylogenetic tree</u> and they are capable to adapt the same environmental niche. Therefore, they should be considered as one species. This can be easily tested via 16S rRNA sequencing.
Answer:
Myocardium
The Heart itself. The nearest organ is the blood supplied to the Myocardium (Heart muscle) by the Heart pumping oxygenated blood through the Coronary Arteries.
Answer:
The skull is from a fossil skull of Styracosaurus - a horned dinosaur.
Explanation:
This skull image is the skull of a Styracosaurus dinosaur who was a huge dinosaur almost 5 meters or more with the horned present on the skull. This is a fossil skull representation from the fossils.
Styracosaurus was present 75 million years ago during the Cretaceous period who was a completely herbivorous ceratopsian dinosaur.
Thus, the skull is from a fossil skull of Styracosaurus - a horned dinosaur.
