Answer:
Proteins.
Explanation:
Ribosomes are complex molecules present in all living cells, they are also called organelles. It serves as the site for protein synthesis. They can be gound freely in the cytoplasm or bound to certain organelles like the endoplasmic reticulum. They consist of two major structural components: the small ribosomal subunits, which read the mRNA, and the large subunits, which join amino acids to form a polypeptide chain.
There are 3 types of Ribosomes which are:
• Ribosomes link amino acids together in the order specified by messenger RNA (mRNA).
• Each unit also consist of ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins.
• Transfer ribosomes (tRNA)
Seismic waves travel in all the directions and used to determine the magnitude of an earthquake. There are 3 types of seismic waves that move in different directions.
1. P wave: It is the fastest of all three waves that travel through the interior of the earth and are compressive waves.
2. S wave: Secondary waves generally follow the P waves and travel through the interior of the earth but are shearing waves.
3. Surface wave: This is the slowest of all three waves that moves close to the surface of the ground.
These waves affect the movement of other materials when they are passing through the interior or surface of the earth.
P waves can move through the solid rocks and even liquids. S waves do not travel through the liquids such as water and molten magma. Surface waves causes shaking of the ground and do not go deep inside the earth.
Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.
Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.
An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.
