Answer: CONSERVATIVE

Explanation:MESELSON-STAHL EXPERIMENT is an experiment carried out by Matthew Meselson and Franklin Stahl in the year 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative.

After the completion of the first replication cycle,it was discovered that the replication is not a complete conservative process but a semi-conservative in nature. It shows that when DNA replicates one of the Helical strand is from the

one strand from the original or old helix and one newly synthesized helix.

Answer: conservative model

Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.

The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.

What happens to energy as you move up food chain
geniusboy [140]
As you move up to the food chain, the energy will decrease. This explains  that the more the consumers, the lesser the energy that the last consumer will get from the sunlight. This is because each energy will decrease as it passes by the consumers because each consumers takes a portion of the full energy from the sun.
