Why are shellfish population often a good indicator of water quality

Biology

Pachacha [2.7K]4 years ago

"Water quality" may include the amounts of dissolved oxygen and the levels of algal growth, pollutants which may be present and the pH level. Water quality effects also which types of organisms can survive in a body of water.
 Shellfish require a high level of dissolved oxygen and their abundance is an indication of good water quality. Shellfish are sensitive to changes in the ecosystem and they cannot easily escape changes in the water quality. These are one of the reasons why shellfish are good indicators of water quality.

True or​ false? A histogram and a relative frequency​ histogram, constructed from the same​ data, always have the same basic sha
kramer

Answer:

True.

Explanation:

Histogram may be defined as the representation of the numerical data in the form of diagram or pictures. The result of any experiment or research data can be easily explained in the histogram.

The X axis and Y axis represent the factors that need to be study with the help of histogram. The same histogram data always represent the same basic shape because they might have different scales but their representation and conclusion represent the same shape.

Thus, the answer is true.

Label the drawing to the right
larisa86 [58]

Answer:

The three processes from left to right are:

<u>Replication</u>   DNA  <u>Trancription</u>  RNA  <u>Translation</u> Protein

Explanation:

The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:

  1. DNA Replication
  2. Transcription
  3. Translation

DNA Replication:

DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.

Transcription:

Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.

Translation:

Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.
