Answer: Option B. core samples
Explanation: this is the only option that is not used for locating minerals
No generations or hybrid would form before meselson and stahl would have observed evidence of a band in the cscl gradient.
The conservative model predicts that, following a single replication, half of the newly formed DNA double helices will be made entirely of the original, or old, DNA, and the other half will be entirely new. Then, each double helix would be completely replicated during the second round of replication. After that, 25% of the double helices would be all new, and 25% would be entirely old. Thus, the fraction of entirely new DNA double helices would increase with each succeeding round of replication, but the total number of completely unique DNA double helices would remain constant. Therefore, no hybrid DNA molecule containing 14N and 15N is replicated in the conservative model.

The chemical processes being done in the body is known as Metabolism. Metabolic processes are constantly taking place in the body.Metabolism is the sum of all of the chemical reactions that are involved in catabolism and anabolism.
The reactions governing the breakdown of food to obtain energy are called catabolic reactions.
That organism might rely on the diffusion of oxygen and carbon dioxide through their outer body covering if it's : B. small and lives in water
Organisms that live in water cannot get their oxygen with the same process like we did on the land. They need the process of diffusion in order to do it
Hope this helps
