Which of these explain how ice cores can be used to correlate atmospheric makeup and climate changes over time?

A) As ice melts into water, the thermal expansion traps gases from the atmosphere that can later be analyzed

B)As ice forms, a latent heat is released from the ice. This causes carbon dioxide levels to increase in the atmosphere.

C) As snow packs freeze and build up gradually over time, gases from the atmosphere are trapped within the ice and can be analyzed.

D) As snow falls onto an existing glacier, methane is released and carbon dioxide is trapped, indicating the makeup of the atmosphere at a particular time period.

Answer is C according to Usatestpep

The right answer is b hydrogen bonds!

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein

We are not able to see the stars. light prevents our seeing the stars. i hope it kinda : )
