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)
Magnetic force - B.
Electrical force - A.
Gravitational force - D.
Contact force - C.
<h3><u>Explanation:</u></h3>
When a charge moves about its path, it produces a magnetic force around it. This magnetic field is perpendicular to the axis of movement of the charge and is directly proportional to the amount of charge, speed of the charge, and inversely proportional to distance between the charge and the point of measurement. Michael Faraday discovered this phenomenon.
Electrical force of attraction or repulsion is seen between the two charged bodies, or one charged body and one uncharged body which can induce charge to the uncharged body. The attraction or repulsion between the charged bodies are seen if the bodies are close enough, and this is called electrical force.
The gravitational force is also a non contact force that is seen between two bodies which is always attractive in nature and is seen between any two bodies.
A contact force like friction is a type of force that takes place only when two bodies are in contact with each other.
Since the
speed of many physiological processes in marine organisms is determined by the
temperature, the first consequence of the changes in the conditions of the
medium becomes offset the timing of seasonal events, such as the timing of
spawning fish. There have also offset migration routes and spawning areas. So,
as a result of warming in the Sea of Japan, spawning navaga shifted to an
earlier date, because of the reduction of the area of "cold spots"
in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab
are lengthened, but because of the temperature rise to the east of Japan,
spawning saury expanding. These changes significantly affect the success of
reproduction, resulting in changes populations of their fishery.
