6 0

Answer:

magnets are used in refrigerator to keep the door closed. it is used in tv and computer screen. magnets are also used in electrical bell.All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.Magnets are important because of their properties A particle moving in a magnetic field feels a force proportional to his speed, and to the field, so you can use a magnet that produce a field in a certain way and shape, in order to catch a particle in motion.

What is the function of the red blood cell ​
Phantasy [73]

Answer:

The functions of RBC ( Red Blood Cells) are as follows:

Additional Information:

<h3>About RBC</h3>

RBC stands for Red Blood Cells. They are also called erythrocytes. They are circular, biconcave, disc-shaped and non -nucleated cells. They are formed in red bone marrows and destroyed in the spleen. Their lifespan is very short that is 4 months.

RBC contains an iron pigment called haemoglobin that carries oxygen from place to place in the form of oxyhemoglobin. When haemoglobin is exposed to oxygen, it turns red. So the blood is red in colour. If RBC is less in blood then, a person is suffering from anaemia , as there is not enough haemoglobin to transport oxygen.

Which of the following refers to the investigative process by which geologists identify and match sedimentary strata and other r
Strike441 [17]

Answer:

Correlation

Explanation:

Correlation simply means matching rocks or strata's of the same age. This rock units or sedimentary strata's may be matched from same region or even different continents.

In correlation the major task is to establish time equivalency of various rocks or sedimentary strata's.

In correlation of rock unit or sedimentary strata, Geologist looks at the physical continuity. For example a sedimentary strata from a region having a particular sequence of rock or sedimentary strata . That same pattern of sequence may be found in another region . With the similarity in the sequence stratigraphy ( sediment layering), Geologist can infer the similarity in age of both strata's.

Fossil contents present in different strata; if similar fossil contents found in different regions, geologist can determine the age similarities.

The first picture indicates strata correlation using fossil similarities while the second picture uses the physical continuity like lithology  to correlates strata's
