Answer:

Heyoooo!

The reservoirs are the atmosphere, the terrestrial biosphere (which usually includes freshwater systems and non-living organic material, such as soil carbon), the oceans (which includes dissolved inorganic carbon and living and non-living marine biota), and the sediments (which includes fossil fuels).

Explain how the data from the river samples showed that there was a problem with the water treatment plant.
Agata [3.3K]

Answer:

The water treatment plant does not work properly.

Explanation:

The data from the river samples showed that there was a problem with the water treatment plant because there is high amount of pollutants are present in the river sample. The presence of pollutants in the samples shows that the water treatment plant did not work properly, if they did no pollutants are present in the river water so this presence of pollutants indicates inefficiency of water treatment plant.

Explain why DNA requires structural robust and efficient storage and organization mechanisms/structures.
wel

Answer:

DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.

Explanation:

DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.

How are archaea and bacteria alike?
Ostrovityanka [42]

Answer:

The correct answer would be b. Their cells are small and lack a nucleus.

Both archaea and bacteria are prokaryotic organisms that is, they both are devoid of a nucleus and other membrane-bound organelles such as mitochondria, chloroplast et cetera.

They also share a similarity in terms of shape and size of the cells. Both of them are unicellular in nature and can not be seen by naked eyes.

They show variations in their genetic and biochemical ways. For example, archae contains three RNA polymerases whereas bacteria contain a single RNA polymerase.

Their cell wall also show variation in composition. For example, a bacterial cell wall contains peptidoglycans, whereas archae cell wall does not.

Thus, we can say that archae and bacteria are similar in a manner that their cells are small and lack a nucleus.
