Which substance is a type of biomolecule that can be used for energy storage and insulation? O A. Nucleic acid O B. Carbon dioxide O C. Lipid D. Protein​

Protein

Explanation:

Protein is used to make insulation (like fat) and is used to store energy taken form food (please tell me if this works)

Lipid

Explanation:Daughter just took test and Lipid is correct!

28869.6J

Explanation:

Given parameters:

Mass of water in flask = 100g

Initial temperature   = 21°C

Final temperature  = 90°C

Specific heat capacity  = 4.184J/g°C

Unknown:

Amount of heat the water absorbed  = ?

Solution:

The amount f heat the water absorbed can be determined using the expression below:

 H  = m x C x Δt

m is the mass

C is the specific heat capacity of water

Δt is the change in temperature

Now insert the parameters and solve;

    H = 100 x 4.184 x (90 - 21)  = 28869.6J
