Answer:
IPCC determines the state of knowledge on climate change. It identifies where there is agreement in the scientific community on topics related to climate change. I hope that was helpful.
Explanation:
Its role as defined in the “Principles Governing IPCC Work” is “to assess on a comprehensive, objective, open and transparent basis the scientific, technical and sociology-economic information relevant to understanding the scientific basis of risk of human-induced climate change.
A.
Sound absorption depends more on the thickness of a material than its color.
Apurinic sites in an intact double helix DNA molecule result from the loss of a nucleotide base.
<h3>What is an apurinic site? </h3>
An apurinic/apyrimidinic/abasic site is a position in a molecule of DNA which lacks any purine or pyrimidine base. These sites are also found in RNA molecules but their frequency is more in DNA molecules.
DNA damage caused by a spontaneous depurination can result in the formation of an abasic site.
In the presence of an abasic site, DNA polymerases cannot function. Thus to maintain the integrity of the genome, these sites need to be repaired.
Two methods to repair are base excision repair and nucleotide excision repair.

When the spring is compressed its potential energy will increase.
<u>Explanation:
</u>
- When you a compress or stretch a spring that you work against the restoring work of the spring the potential energy of the spring increases.
- This work is stored as the elastic potential energy of the spring. The potential energy increases with displacement from the equilibrium position of the spring
- So, when the compression is doubled its potential energy increases double the time along with displacement.
