Meselson and Stahl were trying to determine if DNA replication was semiconservative, conservative, or dispersive by labeling E.

coliDNA with a regimen of heavy nitrogen (H) for one round of replication and then transferring these cells to light nitrogen (L) for two more rounds of replication. Which of the following statements wouldnotbe true within the context of this experiment?a. If DNA replication were conservative, no DNA molecules of intermediate density (H-L) would have been seen.b. If DNA replication were dispersive, only DNA molecules that were of intermediate density (H-L) would have been seen.c. If DNA replication were semiconservative, the DNA molecules that were made would all continue to be heavy density (H-H).d. If DNA replication were semiconservative, the DNA molecules would consist of one parental strand basepaired to one newly replicated strand.e. If DNA replication were semiconserative, a higher proportion of DNA molecules from future divisions would have been low density (L-L)

Answer:

Option C

Explanation:

All of the following options are correct except option C. in the Meselson Stahl experiment, after the first round of replication, the DNA molecules made consisted mainly of one parental strand and one new strand each which is the DNA molecules of intermediate density (H-L). Then future replications will produce more of the low density L-L density. This form of replication is thus termed to be the semi conservative form of replication

Choose all of the following that are examples of SECONDARY SUCCESSION? a. wild fire b. volcanic eruption c. glacier melting d. f
inn [45]

Answer:

i think it would be A for wild fire, D for flood and E for Tsunami

Explanation: wild fire are one of the most common ways for a secondary succession that can bring change when the environment is disturbed or damaged. For instance, by allowing fast-growing plants to grow and provide a source of food and shelter for many animals to use and eventually draw them back into the ecosystem. Both flooding and tsunamis help push older organisms and other stuff from the environment to create for room for other plants and animals to come and keep the ecosystem healthy and ongoing.

i hope this can help you with your work mate!

The correct answer is letter A, the increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.

This is one of the many chain reactions that agricultural farming brings to the environment, and it will be very common through the years as people have not figured out a safer way to protect crops.

Water is a limited natural resource, vital for the expansion and development of, not only our specie, but each individual living organism in the planet. Hence, in a community proper water management is a must in order to make sure that water be maintained and cared for -used wisely. In one research, it is estimated that by 2025 more places will feel water scarcity than decades ago.
