Symbioses are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called mutualisms.
In mutualism the relationship benefits the two organisms, the relationship can be within the species, between living things fro two different species among others. Example is the digestive bacteria and humans; Some food cannot be digested, therefore when these foods are consumed, the bacteria in the digestive tract feed on these foods, therefore the bacteria stays alive and humans gets helps in digestion.
I may be wrong but i think it is B. <span>call 9-1-1 or the local emergency number quickly, then return to give care to the child.
I hope this is right</span>

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: Cell Wall
Explanation: Both archaea and bacteria have a/n Cell Wall, but it is made of peptidoglycan in bacteria and pseudo peptidoglycan in archaea.
