The scientists are interested in bubbles of atmosphere trapped in the ice cores. By the depth of the ice, they have some idea of the age of the atmospheric bubbles. By the composition of gasses in the trapped air, they can determine the proportions of atmosphere made from the composite gasses: nitrogen, oxygen and carbon dioxide and a few other gasses. This is how scientists have determined that the proportion of carbon dioxide has increased in our atmosphere since the Industrial Revolution.

Describe how plants play a role in the cycling of matter through photosynthesis.
tatuchka [14]
Photosynthesis has a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur hope this helps :)

What is the texture and consistency of the dna? 2. why did we use a salt in the extraction solution? 3. is the dna soluble in th
lions [1.4K]

Explanation:

These questions are related to the extraction of DNA using detergents and ethanol.

1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.

2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.

3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.

4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.

5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.

5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
