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:
Eat fig and do exercise every day
Your answer is the peripheral proteins. Its on the inner or outer surface of the phospholipid bilayer, but not embedded in its hydrophobic core.
Answer: A food chain or food web provide information on the eating patterns of organisms, how energy is transfered from one organisms to another and the flow if energy in the ecosystem.
Explanation:
Food chain is the link of network that that starts from producer to the consumer and finally ends at the predator species and decomposer species in the ecosystem. It describe the feeding relationships among organisms.
Food web contains interconnection of several food chains in the ecosystem. It shows several feeding relationships in food chains .
Both food chain and food web provide information of how organisms are interconnected, their eating patterns, how energy is transferred from one organisms to another and flow of energy in the ecosystem.
