Answer:
Structurally, the ribosome comprises of two major parts: The small ribosomal units and the large ribosomal units. Each unit contains ribosomal Ribonucleic acid molecules, which is usually one or more than one called rRNA. Each unit also contain ribosomal protein, rproteins. Each of these components are very important for the translation of messenger RNA into proteins encoded by the RNA.
Explanation:
The ribosome and its components are generally referred to as translational apparatus. The small subunit of the ribosome is effective in reading the codes encoded on the mRNA, which . The large subunit is needed to actually join the amino acids needed to form the right protein (or polypeptides). The proteins within the ribosome is used to act as a scaffold that only aid the ribosome ability to form polypeptides.
Since both prokaryotes and eukaryotes are constantly forming proteins using the amino acids they accumulated through nutrition, therefore, both groups possess ribosome. However, the percentage of rRNA and protein in each group differs. For prokaryotes, the rRNA to protein ratio is close to 2, while in eukaryotes like human is close to one.
Endoplasmic reticulum is an organelle within a cell. It is divided into smooth and rough endoplasmic reticulum. Smooth endoplasmic reticulum is involved in synthesis and transportation of of lipids while rough endoplasmic reticulum contains ribosomes which are responsible for synthesis of proteins, therefore rough ER is involved in transportation of proteins. A few proteins are synthesized in the mitochondria and the plastids. Therefore, proteins synthesized elsewhere other than the rough ER are the Mitochondrial proteins
Answer: Density affect propagation.
Density is mass per unit volume of a substance.
A substance that is more sense has more mass per unit volume, it will make sound to transmit at slower rate . Less dense substance will allow sound to transmit at higher rates. Density affect the speed a wave will be transmitted through it. The denser the material, the slower wave will be transmitted.
Explanation:
Density is Mass per unit volume. Density affect the propagation of wave. The denser the substance, the slower wave will be transmitted through it. The less dense the material, the higher wave will be transmitted through it. Density affect the speed of wave.
