Answer:

A) allopatric speciation

Explanation:

  • Allopatric speciation is a type of speciation that is caused due to geographical isolation that results in the separation of the population of the same species that once inhabited the same geographical area.
  • Due to this geographic separation, the species become so isolated that no more gene flow occurs between the two species and therefore, with time new species get formed.
  • The various geographic changes that can contribute to the separation of the two species can be - formation of mountains, islands, water bodies, glaciers, etc.
  • The populations that get separated due to the geographic barriers are subjected to different selective pressures and hence, speciation occurs.

Kisachek [45]

The given blank can be filled with dinosaur footprints.  

In the Precambrian, the sedimentary rocks deposition took place in the Blue Ridge Province of Virginia, however, no fossils have been positively determined from these deposits. The Paleozoic rocks are well documented in Virginia. The occurrences of shallow area deposition were obstructed by subsequent periods of erosion and mountain-building incidents.  

The withdrawal of the widespread shallow regions of the Paleozoic left much of the state exposed at the time of Mesozoic and Permian. In central Virginia, fossils of freshwater fish, dinosaur footprints, and insects are found in the rift basin deposits of the Triassic.

Spica casts or body casts are used to treat children who have hip, pelvis, or leg problems, such as developmental dysplasia of the hips.  When elevating the head of an infant in a spica cast the nurse should use pillows to elevate the head and shoulders of the infant. Spica cast is not a surgical procedure but normally used after a surgical procedure for hip dysplasia.

Question 15 of 25
Lady_Fox [76]

Answer:

D. The organelles are enclosed in membranes

Explanation:

One defining characteristic of eukaryotes is that they have membrane-bound organelles. If a cell lacks a water-storing vacuole, that could mean it is a prokaryote too. If a cell lacks a Golgi apparatus, it can never be a eukaryote. RIbosomes are characteristics of both prokaryotes and eukaryotes. D. is the best evidence that the cell is a eukaryote.
