Based on morphological and molecular data, researchers hypothesize that the split between dugongs and proboscideans likely occur

Answer:

Molecular and morphological analyses of dugongs and proboscideans should be performed.

Explanation:

From a molecular perspective, comparing the genetic sequences of dugongs and proboscideans can reveal the degree of homology between relevant genes, thereby helping to define evolutionary connections between species. Additionally, techniques like mass spectrometry (MS) allow for comparisons of proteins in fossils over one million years old, potentially providing insights into the evolutionary lineage of one group.

The cheek smear slide is made by taking a q-tip or toothpick, rubbing it on the inside of your mouth (to remove cells) and then
Tresset [2298]

Answer:

The count of cells observed will rely on the dimensions of both the cells and the size of the red circle on the slide.

Explanation:

Cells come in varying sizes and this variation affects how many cells can be seen through a microscope. The way the smear is prepared also plays a role, as does the amount and type of dye used on the slide.

In conclusion, the number of cells visible is somewhat subjective and can only be definitively calculated through experience.
