What does the pyramid of biological magnification

1 answer:

6 0

For the answer to the question above asking what does the pyramid of biological magnification. Biomagnification, also known as amplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain. DDT was a commonly-used pesticide before its dangers became known. In some aquatic ecosystems, organisms from each trophic level consumed many organisms of the lower level, which caused DDT to increase in birds (apex consumers) that ate fish.

You observe a tiny structure under a microscope.what question would ask and then investigate to determine whether the structure

anygoal [31]

Answer:

The question to be asked an investigated when observing a structure under the microscope to determine whether it is living is if it has a nucleus if eukaryote or nucleoid if prokaryote.

Explanation:

The major organelle that must be present in all living cells is the nucleus or nucleoid and the protoplasm. The observation of the cell under the microscope will show the subcellular entity, nucleus/nucleoid, more pronounced than other organelles in the cell. The nucleus house the necessary information for the maintenance and reproduction, which is mainly the genetic information that dictates the translational protein products that are needed to build another aspect of the cells. Therefore, when such a tiny structure is placed under the light microscope under the view of oil immersion, the nucleus of the cell should be visible if it is a living structure.

In a eukaryotic cell, the DNA is enclosed in the nucleus, whereas the ribosomes that make proteins are located in the cytoplasm.

Leya [2.2K]

Answer:

The genetic information in DNA is carried to the cytoplasmic protein-manufacturing centers in form of mRNA.

Explanation:

The process of transcription forms RNA using the DNA template strand thereby copying the genetic information of DNA into the nucleotide sequence of mRNA.

The mRNA leaves the nucleus and enters the cytoplasm to join ribosomes. The nucleotide sequence of mRNA is read in the form of triplet codons to specify the amino acid sequence of the proteins.

In this way, mRNA serves as a carrier of the genetic information in DNA.
