Answers
Answer:
1)Inhalation and Exhalation of living organisms is known as respiration
2)The process in which plants produce their own food with the help of sunlight and a green colour pigment chlorophyll.
3)A thing which attracts metal through north pole and south pole.
4)Rate of flow of charge/charge per unit time.
Answer:
Respiration: It's the process in which living organisms take in oxygen and release carbon dioxide to make glucose.
Photosynthesis: It is the process in which green plants prepare their food in the presence of chlorophyll and sunlight by using carbon dioxide and water.
Magnet: It is a substance which has the property of attracting another magnet or a magnetic substance. They have two poles-North and South. The poles of a magnet always point in the north-south direction. The poles of a magnet are opposite to the geographical poles of the earth. Like poles of two magnest attract each other while unlike poles repel.
Electric current: It is the energy produced when an electron passes through a conductive substance. It is produced when the number of electrons in an atom is not equal to the number of protons in the atom. This cannot be done by removing a proton as the nucleus will burst when we seperate a proton, so it is produced by passing an electron into a conductor.
