2. Give a brief description of evolution.
Ans: Evolution:
In this part of Class 10 Science Chapter 9, you will not only learn about the evolution of humans but also the evolution of animals and birds.
Homologous and Analogous organs are the ones which are used in the evolutionary relationships of animals.
There are various stages of evolution. You shall read about the artificial selection, in which one particular species will evolve into various species.
Phylogeny is considered for the evolutionary relationship of biological species.
Humans from primates evolution is still a big mystery and here, you will learn some more details about it.
Here, you will also understand what is somatic variation and Gametic variation and they occur in somatic cells and germ cells of the body. You will also read about the importance of variations and what are the causes of variations.
3. Explain about magnetic field and field
lines.
Ans: Here, the topic discusses field and field lines where magnetics play a major role. Attraction or repulsion of objects can be seen in magnetic fields. Nickel, Iron and Cobalt are the best examples of magnetic fields. You will also read about:
North and south poles
Like poles repel and unlike poles attract
-
Bar magnet
Magnetic field
Magnetic field lines
Iron filings test around a bar magnet
No two magnetic field lines intersect
The relative strength of magnetic field inferred from magnetic field lines
Magnetic field lines form a closed-loop.
Here, the concept also educates you on the concentric circles which are used to represent at every point over a conductor. This will be explained to you with various experiments such as Oersted’s experiment, electromagnetism and electromagnet, magnetic field due to a straight current-carrying conductor, right-hand thumb rule, magnetic field due to current through a circular loop and magnetic field due to current in a solenoid.

They will also study the concept of photosynthesis in detail. They will even study the process of digestion in human beings in detail and will learn about the different organs of the digestive system and how different organs help in the digestion of food. The process of excretion and how waste products are excreted out of the body is also a part of life processes.
6. Why are life processes important?
Ans:Life processes are important for healthy living. Life processes such as respiration, digestion, absorption, assimilation, and excretion are vital for all living organisms. The processes may differ from one organism to another. Students of Class 10 science will learn about the different life processes in Chapter 6. It is an interesting chapter and an essential one if the student wants to pursue a career in Biology.
7. If there is less air in the trachea, its walls do not collapse. Give a reason.
Ans: The trachea is a tube through which we breathe in air and give out carbon dioxide. The trachea is made up of small rings arranged in the form of C. The rings are muscular and made of connective tissue. Thus, the rings present in the trachea help prevent it from collapsing when there is no air in it. The muscular rings expand when air enters into it and contracts when air moves out of our lungs.

8. What is the process of digestion and where does the complete digestion of various components of food take place?
Ans: Digestion of food takes place in different organs. In the mouth, the process starts by chewing food. Then it passes to the stomach for further digestion. The small intestine is the part where complete digestion of food takes place. Different juices and enzymes present in the different parts of the digestive system help in the complete digestion of the food. The digestion starts in the mouth and breaks into small molecules that are digested quickly in the stomach and other parts of the digestive system.
9. Explain how urine is produced?
Ans: Urine is the waste product excreted out of the body. Urine is produced in the kidneys. It consists of harmful substances. Therefore, it is necessary to pass out the waste products in the form of urine. Kidneys filter the blood and important substances such as glucose, amino acids, and salts are reabsorbed. Excess amounts of water present in the blood and other waste substances are converted into the urine and it is excreted out through the urinary system.
