Answer:
It is composed of protein
Explanation:
DNA is the stored form of the genetic material in living organisms. DNA is a long chain polynucleotide made up of nucleotide subunits. The nucleotides are monomers that comprises of a five carbon sugar (Deoxyribose), a phosphate group and nitrogenous bases (Adenine, Guanine, Cytosine and Thymine). A DNA molecule has segments that holds the information to build an organism and pass genetic traits to offsprings. This segment is called GENE.
However, before this genetic material can be passed on to an offspring or be used in an organism's growth and development, it needs to divide into the cells that require it. Before it can divide into the cells, it needs to be replicated in order for each cell it is dividing into, to have an equal and correct number.
The DNA is also capable of change in its nucleotide sequence so as to achieve genetic variation.

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.

Answer:
Thanks to its high specific heat, water plays a very important role as a temperature regulator
Explanation:
The specific heat is the amount of heat needed per unit mass to raise the temperature one degree Celsius. The specific heat of the water is 1 calorie / gram. Water is one of the substances with higher specific heat and this is why water plays a very important role as a good temperature regulator.
Water changes its temperature, absorbs or loses a large amount of heat but only changes, either by increasing or decreasing its temperature very little. This property is essential for living beings as it reduces drastic changes in temperature. It also helps that our body does not overheat or over cool since this property helps us maintain thermal balance.
