One explanation could be the differences in climate (environmental factors). The climate in northern Mexico could support the reproduction of the mosquito species, which is a vector of the dengue virus. Other environmental conditions that influence its endemicity could include living conditions and sanitation. The other possiblity could be that the people in the US have developed immunity for the disease, therefore, are unaffected even when infected by the virus.
Diffusion is a spontaneous process in which molecules move with their concentration gradient. For example, if you place food coloring in water, the food coloring will slowly diffuse through the water until the entire solution has been balanced.
Osmosis is specifically the movement of <em>water</em> through a semipermeable membrane - meaning a membrane that can let some substances in but keep others out - and, similar to diffusion, it moves with its concentration gradient. For example, if you place a glucose solution sealed in plastic in water, water will move into the plastic to even out the concentration of glucose in the entire solution because glucose is too large to diffuse freely.

Answer: Homologous structures
Explanation: They are structures which have similarities in various organisms but carry out opposite functions. This is the opposite of analogous structures
Creating a genetic duplicate of an organism using biotechnological methods is known as reproductive cloning.
<h3>Reproductive cloning</h3>
Cloning generally refers to the production of clones.
Clones are exact copies of an organism or something.
When it comes to living organisms, clones are both genetically and physically the same.
Thus, creating a genetic duplicate of an organism is a form of cloning known as reproductive cloning.

Coral does not have a radial symmetry.
radial symmetry - symmetry about a central axis, as in a starfish or a tulip flower.
So, C is the answer.
