Answer:
A. The poles are opposite
Explanation:
Magnets are object that produce magnetic fields, which are regions of space that exert a forces on charged particles in motion or on other magnets.
Every magnet has 2 opposite poles, which are labelled by convention as North Pole and South Pole; the lines of the magnetic field of a magnet go out from the North Pole and go into the South Pole.
Magnetic poles always exist in pair: it means, every magnet always contains a North Pole and a South Pole. If a magnet is cut in a half, each half of the magnet will still have a North Pole and a South Pole.
Each pole exerts a force on another pole; in particular, we have:
- Like poles (north-north or south-south) repel each other
- Opposite poles (north-south) attract each other
In this problem, a magnet is attracted to a metal object: this means that the two poles must be of opposite polarity. Therefore, the correct option is
A. The poles are opposite
Answer:
The given figure depicts the process of translation.
Translation is the process by which the mRNA is deciphered into the amino acid sequence of the polypeptide chain.
Ribosomes serve as the site of the translation.
The small and large subunits of the ribosome form the complex around the start codon of the mRNA.
It created three sites namely; A, P and E sites.
A site is a site where the charged tRNA enters the complex.
It then adds the amino acid specific to the codon sequence of the mRNA to the growing polypeptide chain at P site.
Uncharged tRNA then leave the complex through E site.
