Answer:
Hypothesis to validate: elephant shrew is more closely related to anteaters than to shrews.
I would obtain DNA from all three organisms and sequence the DNA to compare the similarities in sequences, the larger the percentage of sequence similarity, the closer the relationship and the more recent they share a common ancestor. I would also compare the sequence of conserved genes specifically as a proxy to determine how genetically related the species are.
Answer:
Order
Organisms are highly organized, coordinated structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex: inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions. In multicellular organisms, similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems.

The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
