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: alpha bond
Explanation:
The carbohydrates popularly called sugars are energy nutrients formed by carbon, hydrogen and oxygen atoms. It is the main energy source of the man and also has a structural or plastic role (formation of parts of cells such as the cell wall, or tissues, such as the exoskeleton chitin of the insects and crustaceans - crab). The small intestine's main mission is to complete the digestion of the chyme. In its passage through the duodenum, it suffers the action of pancreatic and intestinal juices and bile. In fact, it is in the duodenum that most digestive secretions are produced. The foods complexes are thus transformed into simple elements, easily assimilable by the body.
Enzymes are protein catalysts responsible for most of the chemical reactions of the organism, is found in all tissues. Amylase acts in the intestine hydrolyzing glucose polymers (starch, amylopectin, and glycogen). The bonds that hold the monosaccharides together and which are easily digested by pancreatic amylase in the intestine are known as alpha bonds. Some examples of sugars that have alpha bonds are sucrose, maltose, and starch.
Answer:The equation of time describes the discrepancy between two kinds of solar time. The word equation is used in the medieval sense of "reconcile a difference".
