10- Gas exchange

In the ninth grade, we studied how cells prepare ATP by eating. Cellular respiration is a process in which the C-H bond in the food is broken down by oxidation reactions and then converted to ATP.

In aerobic respiration, oxygen is used and complete oxidation of foods. Organisms get the oxygen they need from their cell, cellular breathing, and deliver it to their cells. The carbon dioxide produced during cellular respiration is extracted from the cells and eventually taken from the body.

In oxygenation and the exit of carbon dioxide are interpreted as gas exchanges. Breathing is a term used by animals to carry oxygen into their bodies and then release them to release carbon dioxide. This is not equivalent to breathing and breathing.

Breathing involves mechanical and biochemical processes, while gas exchange is the only mechanical or physical process of breathing. In this 10th class biology book in English pdf chapter, we will go through the method of gas exchange between plants and humans.

11-Homeostasis

Despite changes in the external environment, homeostasis can be defined as maintaining the body's internal conditions on balance.

For example, despite working in ambient temperatures, the human body's core temperature is around 37 C. Similarly, despite eating a diet rich in carbohydrates, blood glucose levels remain about 1 gram.

Physical cells need an internal environment in which conditions do not change much. Stable internal conditions are critical for the efficient functioning of enzymes. The following are some homeostasis processes.

It is the maintenance of the amount of water and salts in the bodily fluids (ie blood and tissue fluid). We know that the process of fencing and osmosis controls the amount of water and salts in the body's fluid and internal cells, which are essential for cell functioning.

(Remember the "concept of toxicity" from IX Grade IX Biology). The maintenance of physiological internal temperature is called thermoregulation. The body's enzymes work best at certain temperatures. Any change in body temperature can affect the function of the enzymes.

12- Contact and control

In the cells of multicellular organisms, tissues and organs do not function independently of each other. They work together to perform many of their tasks as per the needs of the entire body. That means these activities are integrated.

Coordination also helps biologists to respond to events in the world around them. A familiar example of harmony is the way in which muscles work together during movement. Its nervous system uses information from its sensory organs and connects those muscles. Because of this harmony, muscles contract in the right order, strength, and length of time. But that's not all. There are many others involved in such activities Types of harmony.

 For example, increased breathing and heart rate increase, blood pressure is adjusted, and excess body temperature is removed rapidly. How is it The activities of life are controlled and coordinated, that is, the body functions as a unit, in which its various organs and systems cooperate and work in harmony with one another.

13-support and movement

Larger-sized organisms need help to keep their body as a mass. This is especially true for organisms that live on Earth. We know that mobility and locomotion are animal characteristics. "Movement" is a generic term that means to change the place or location through the whole body or its organs.

There are two types of movements, namely the movement and locomotion of the organs. Locomotion is the movement of an animal from one place to another. In this chapter, we will study the human skeletal system (Skeleton), which is primarily responsible for support and mobility.

14- Reproduction

Reproduction is defined as the production of individuals of the same species, the next generation of species. Although it is one of the basic characteristics of animals, it is not an essential life
Processing is thus essential for the continuation of this species.

This ensures that the genetic material of one generation passes on to the next. Each generation produces more and more springs for the next generation. Many people die for various reasons such as diseases, competition, genetic factors, etc. before they reach reproductive age. I hope you 10th class biology book English medium pdf free download now.

Only the best and the best living can reach reproductive age. This ensures that beneficial features will pass on to the next generation. In the previous classes, we have learned two basic types of production.

Irrelevant reproduction means a cell division that produces a perfect copy of the organism. There are several types of irrelevant production that we will discuss in the next pages. Sexual reproduction involves the fusion of male and female sexual cells, called gametes.

15-Inheritance

For the most part of human history, people were unaware of the scientific details of how children inherited the characteristics of their parents. People have always thought that there was some inherent connection between parents and children, but the mechanism was not understood.

Many of the answers to questions about getting features from their parents have come from Gregory Mendel's work. In this chapter, we will go through the discovery of Mendel's work and other legacies. Genetics is a branch of biology in which we study inheritance. Inheritance means the transition from parent to spring. These qualities are called traits.

For example: In human height, eye color, intelligence, etc. are all inherited traits. Parents introduce their young to the features through gene transmission. During the fertilizer, equal chromosomes are collected from each parent. The chromosomes carry the units of inheritance called genes.

16- Man and his environment

Each organism has its own specific surroundings or environment with which it interacts permanently and is completely shielded. A biological environment is a combination of physiological (bionic) and biological (biotic) conditions that affect this organism.

The study of the correlation between organisms and their environment is called ecology. In ecology, the level of organization ranges from biology to biosphere. An organism can be unicellular or multicellular. A group of organisms of the same species in a particular geographical area (habitat) is called a population.

All the communities that live in the dwelling and interact with each other in different ways are collectively called a community. If you want complete details then download biology 10th class Punjab textbook pdf for free.

17 -Biotechnology

Humans have been using biotechnology ever since they discovered the farm. It is used for speed control, from planting to controlling plant growth and crop production. Cross-pollination of plants and cross-breeding of animals was one of the major biotechnology techniques.

These techniques were used to enhance product quality and meet specific needs. In this chapter, we will get a basic understanding of the techniques used in biotechnology. Biotechnology has been defended as the use of organisms in the process of producing useful products or services.

Fermentation and other processes based on the biological ability of the organism are generally regarded as the oldest biotechnology.

18- Pharmaceuticals

Pharmaceuticals is a study of drug composition, properties, and medical applications. Drug sources are also studied in pharmacology. Clinical pharmaceuticals existed in the Middle Ages. Early pharmacologists focused on natural substances, especially plant extracts.

Pharmaceuticals developed in the 19th century as biomedical science. Any substance that, when absorbed into a body by an organism, changes the normal function of the body, known as medicine. Drugs have been broadly classified into two types.
