Proper environmental sanitation and the use of insecticides will prevent the spread of dengue fever virus.
<h3>What is a disease vector?</h3>
A disease vector is an organism which transmits pathogens to other organism.
Aedes aegypti mosquito is the vector for dengue fever. It transmits mosquito through its bite, thus introducing the virus into the blood.
The use of insecticides and the proper sanitation will help prevent the transmission of diseases.
At home, use of insecticide-treated nets will help prevent the spread of dengue fever.
Therefore, proper environmental sanitation and the use of insecticides will prevent the spread of dengue fever virus.

#SPJ1
Plants use energy from sunlight to turn water and carbon dioxide into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”
Answer:
The chemical reaction is: AB + CD ---> AC + BD (ΔH= - )
Explanation:
After the reaction between two reactants, two products are generated.
As the products have less energy than the reactants, this energy is released and ΔH is negative
Absolute Brightness
Absolute brightness represents
the total amount of energy emitted from a celestial object. It is the measure
of the true brightness of a star or other celestial object as it would be as
seen from a standard distance<span> of
exactly 10 parsecs (32.6 light-yea</span>rs). The more luminous an object, the smaller the
numerical value of its absolute magnitude or brightness.
