One more thing, unlike the other books, which you will come across for the 10 th class, each chapter in the biology 10 th class book by PTBB is different from others. Even if a student starts studying from the middle of the book, it will still make sense as each chapter deals with an entirely independent concept.
That is why it is straightforward to cram the book; one more thing, the entire book is crammable; you can learn by heart every detail and still score the highest marks. However, if you want to pass the entry tests, it is better to consider the concepts.
Oxygen is a symbol of life, and to explore how this significant gas and carbon dioxide play their role in the life-essential process of breathing, students will have to concentrate on this chapter. As humans and plants depend on each other for breathing, it is important to understand the breathing process and gaseous exchange at the plant and human levels. The entire chapter revolves around these two topics.
However, the major concern of this section is the gaseous exchange in humans. The last section of this chapter is about respiratory disorders, their symptoms, and causes. It is relatively introductory and easy to learn. Still, the similarities and differences among the diseases can confuse the learner. The human body can only function at an optimum level. Otherwise, we may die or fall ill. This chapter is about how our complex body systems manage to keep a balanced temperature, body fluids level, and toxin levels.
The chapter starts with the homeostasis in plants and how different plants are classified into various types only because of their balancing water levels and temperatures for survival.
The next main part of the chapter is about the human body and homeostasis; both main balancing organs of the human body, skin, and kidneys are explained. The last section of this unit is about kidney diseases and their treatment. This is the most interesting chapter, including both the central and peripheral nervous systems. On top of it, students will be introduced to the new concepts of hormones.
It is entirely new for students as in the previous classes; the Punjab curriculum board has not introduced it. Even though it is a difficult chapter with so much new to learn, but students will still find it interesting. From neurons to the brain and from hormone production to the glands, everything is thoroughly described.
How come we claim to have passed higher secondary school with a biology major and not know anything about bones and muscles. Hey there! This post could not be written any better! Reading this post reminds me of my old room mate! He always kept chatting about this. I will forward this post to him.
Pretty sure he will have a good read. Thank you for sharing! I have heard good things about blogengine. Is there a way I can transfer all my wordpress posts into it?
Any kind of help would be really appreciated! I am very happy to read this. This is the kind of manual that needs to be given and not the random misinformation that's at the other blogs. Appreciate your sharing this best doc. I know this is kinda off topic but I'd figured I'd ask. Would you be interested in exchanging links or maybe guest authoring a blog post or vice-versa? My website goes over a lot of the same topics as yours and I believe we could greatly benefit from each other.
