I said Ho2 since it’s carbonated. It moves up the plant against the force of gravity and hence that water molecules are cohesive meaning (they stick together). So when some are pulled into the lead others follow

Against gravity, is called the transpiration stream

Water rises through xylem vessels due to two key properties of water – cohesion and adhesion

Cohesion:

Cohesion is the force of attraction between two particles of the same substance (e.g. between two water molecules)
Water molecules are polar and can form a type of intermolecular association called a hydrogen bond
This cohesive property causes water molecules to be dragged up the xylem towards the leaves in a continuous stream

Adhesion:

Adhesion is the force of attraction between two particles of different substances (e.g. water molecule and xylem wall)
The xylem wall is also polar and hence can form intermolecular associations with water molecules
As water molecules move up the xylem via capillary action, they pull inward on the xylem walls to generate further tension

Answer from: Quest

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
