Protein synthesis is the main function of which of the following structures? (A) Nucleus (B) Ribosome (C) Chromosome (D) Mitocho
Mars2501 [29]

Answer:

B. Ribosome

Explanation:

Ribosomes are the organelles that serve as a site for protein synthesis. Each ribosome has two subunits. The small subunit first joins with mRNA and the initiator tRNA to start the process of protein synthesis. The large subunit joins the complex and the proteins are synthesized according to the nucleotide sequence of the mRNA read in the form of genetic triplets. Ribosomes are present in cytosol as well as on the surface of the rough endoplasmic reticulum of a eukaryotic cell. In both locations, they are involved in the process of protein synthesis.

Describe the role of the ribosome in the cell

Ribosomes are what make up proteins (the protein builders). There are a lot of ribosomes in the cytoplasm.

Explanation: Ribosomes connect mRNA(messenger RNA) and tRNA (transfer RNA) to synthesize polypeptides and proteins. Proteins are made up of building blocks amino acids. Polypeptides are chains of amino acids and portions of proteins in cells.

(Also, ribosomes are usually the small dots that you see in a cell diagram)

During warmer parts of the day, fish will be found in deeper waters of a lake. Which statement best explains this phenomena with
Gennadij [26K]

Answer:

The statement that can best explain why during the warmer parts of the day, fish are found in deeper waters of a lake is that warmth lowers the oxygen concentration near the surface.

Explanation:

Organisms in any aquatic ecosystem require oxygen to perform their functions and survive. But the availability of dissolved oxygen in water, especially at the surface, can be affected by environmental temperature.

  • <em>Warm temperature decreases the dissolution of oxygen in the lake surface water, encouraging fish to move to deeper areas. </em>
  • <em>Lower temperatures increase the dissolution and availability of water at the surface, so fish can be found closer to the surface when the weather is cold. </em>

This behaviour of dissolution / availability of oxygen at the lake surface can be observed with seasonal changes or with temperature changes between day and night.
