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.
Answer: yes

it is located at the bottom of the right ventricle
Answer:
A river basin or drainage basin is an area of land drained by a river and its tributaries. The edge of the drainage basin is known as the watershed. This can be compared to a sink or basin, which catches the water falling into it. The water travels towards the centre and leaves the sink through a plug hole.
Answer:
Water has several very unique properties, like surface tension, cohesion, and adhesion because water is polar and every water molecule electrically attracts the neighboring water molecules.
Explanation:
Water is a universal solvent and has several unique properties like surface tension, adhesion, cohesion, high specific heat, etc.
In a water molecule, the oxygen atom's nucleus attracts electrons more strongly than the nuclei of hydrogen atoms. The negatively charged electrons are pulled toward the oxygen atom's nucleus and away from the hydrogen atom nuclei. As a result, a negative electrical charge occurs in the middle part of the water molecule near the oxygen atom and a positive charge near the other parts of the molecule (hydrogen atoms). This unequal distribution of electrical charge between different parts of the water molecule (polarity) makes it a polar molecule.
The positive part of one water molecule (hydrogen atoms) is attracted to the negative parts of neighboring water molecules and as a result, hydrogen bonds are formed between hydrogen and oxygen atoms of adjacent water molecules. These hydrogen bonds between molecules help hold water molecules together.
