The Relationship between Biology and Human Life 30

This world is the handiwork of God, including us humans and all kinds of creatures.

When we study living things and ourselves, we are studying God's works and finding the eternal iron law in the universe. Recognize yourself, develop yourself, and live a better life.

You can say a lot, but if you talk too much, it becomes philosophical.

Human beings are constantly exploring the mysteries of the biological world, gradually understanding various life phenomena, and exploring the laws of various life activities.

Discovery of penicillin.

Synthesis of artificial bovine insulin.

The founder of the world's replanting.

Discovery of penicillin.

One day in 1928, Fleming was studying staphylococcus bacteria, which cause fever in the human body, in one of his modest laboratories. Since the lid was not properly closed, he noticed that the agar used to grow the bacteria had a layer of Penicillium attached to it. This was from the window of a scholar who studied penicillium upstairs.

To Fleming's surprise, in the immediate vicinity of Penicillium, the staphylococci suddenly disappeared. Fascinated by this serendipitous discovery, he managed to grow the mold in several experiments that proved that penicillin could kill all staphylococci in a matter of hours. Fleming thus invented penicillin, the nemesis of staphylococcus.

Due to the discovery and mass production of penicillin, the lives of millions of patients with pneumonia, meningitis, abscesses, and sepsis were saved, and many wounded and sick people were rescued in time. The advent of penicillin caused a sensation in the world at that time. In recognition of this contribution to the benefit of humanity, Fleming, Chann, and Florey were jointly awarded the Nobel Prize in Medicine and Physiology in 1945.

In 1965, Chinese scientists used biochemical methods to synthesize the world's first biologically active protein - crystalline bovine insulin. It marks that China has made important achievements in understanding life, unraveling the mysteries of life, and exploring the origin of life.

In 1963, Chen Zhongwei, a medical worker in China, successfully replanted the severed limb with the cooperation of his colleagues, and later reactivated various severed limbs (including severed fingers).This achievement has maintained a leading position in the world to this day, and Chen Zhongwei has been praised by the international medical community"The founder of the world's replanting. ".

Biology. We call the science that studies the phenomena of life and the laws of life activities biology.

Biological science is a science based on the introduction of the world and all living beings, and is closely related to people's lives. Biology, as a basic science, has traditionally been the foundation of agronomy and medicine, involving cropping, animal husbandry, fishery, medicine, pharmaceuticals, health and so on. With the continuous development of biological theories and methods, its application fields are constantly expanding.

Now, the influence of biology has gone beyond the traditional fields mentioned above to extend to food, chemical industry, environmental protection, energy and metallurgical industry, etc.

Summary. Solution: Biology is a natural science that studies the structure, function, occurrence and development of organisms, the relationship between organisms and the surrounding environment, and other sciences Biology has a very close relationship with human life in terms of clothing, food, housing and transportation, and biology is very important for continuously improving the living standards and quality of life of human beings and helping human beings live in harmony with nature For example, the knowledge of microbiology plays an important role in food production and food preservation

Therefore, biology is closely related to agricultural production, industrial production, medicine, and environmental protection

Timber, gasoline, diesel for transportation**: ancient organisms, vaccines for vaccination**Coarse: microorganisms and other issues are inseparable from biology Therefore, biology is closely related to agricultural production, industrial production, medicine, and environmental protection

Solution: Biology is a natural science Graduate students of the structure, function, occurrence and development of the law, the relationship between biology and the surrounding environment and other sciences Biology and human life have a very close relationship with clothing, food, housing, and transportation, biology is very important for continuously improving the living standards and quality of human life, and helping human beings to live in harmony with nature For example, the knowledge of microbiology plays an important role in the production of food raw eggplant celery and food preservation

Hope mine is helpful to you.

I wish you a happy life and a happy day!!

1. Human health is related to biology

Some harmful bacteria, fungi and viruses and other microorganisms can cause people to get sick, and most of the traditional Chinese medicine with disease prevention and healing effects is plants, and a few are animals, microorganisms and minerals. Antibiotics are the product of microbial life activities. It can be seen that human survival, life, production and health are inseparable from living things.

Without living things, there would be nothing for humans.

2. Human survival is inseparable from withered organisms

Humans and organisms are constantly inhaling oxygen from the air and exhaling carbon dioxide to sustain life; When coal and gas are burned in factories and homes, oxygen is also consumed and carbon dioxide is produced. According to this calculation, in the long run, there will be less and less oxygen on the earth, but this is not the case. Because there are many green plants growing on the surface of the earth, they are able to photosynthesize, absorb carbon dioxide, and produce oxygen, so that the content of oxygen and carbon dioxide in the air is roughly balanced, ensuring normal human breathing, so that human beings can survive.

Organisms and humans are in an inclusive relationship.

Biologically, humans are classified as hominoids, chromosome 2 and orangutan chromosome C centromere fusion (equilibrium translocation) association mode proximity of more than 16n, and multiple interarm inversions, the rest of the chromosomes have strong homology, is a higher animal.

Biology is a living individual. The most important and basic characteristics of living organisms are their metabolism (also known as secretions) and heredity.

Organisms have anabolism and catabolism, which are two opposite processes, and can reproduce, which is the basis of the phenomenon of life. The natural world is composed of living and non-living matter and energy, and inanimate (including matter and energy) are called non-living things, (metabolism is the most essential difference between living and non-living things).

Life science is a science that studies the nature, characteristics, occurrence and development laws of life phenomena and life activities, as well as the interrelationship between various biological rights and between organisms and the environment. It is used to effectively control life activities, actively transform the biological world, and benefit human beingsLife science is closely related to human survival, people's health, economic construction and social development.

While focusing on the cultivation of logical thinking, the discipline of biology also has unique complexity, flexibility, holistic and systematic thinking, which is conducive to students' objective view of the life world and is conducive to students' social adaptation.

1. Birds can fly freely in the air with their wings spread. As early as more than 400 years ago, the Italian Leonardo da Vinci and his assistants carefully dissected birds, studied their body structure and carefully observed their flight. An ornithopter was designed and built, the world's first man-made flying machine.

2. Fish have the ability to come and go freely in the water, so people imitate the shape of fish to build ships and imitate fins with wooden oars. Legend has it that as early as the Yu period, the ancient working people of our country observed the fish swimming and turning with the swing of their tails in the water, and they set up wooden oars on the stern of the boat. Through repeated observation, imitation and practice, it was gradually changed to an oar and rudder, which increased the power of the ship and mastered the means of making the ship turn.

3. Flies are the spreaders of bacteria, and everyone hates them. However, the wings of flies (also known as balance sticks) are "natural navigators", and people imitate them to make "vibrating gyroscopes". This instrument is already being used in rockets and high-speed aircraft, and it has achieved autonomous driving.

4. Most of our pure clothes are genetically modified colored cotton, and the soybeans we eat are genetically modified soybeans, triploid seedless watermelon, space pepper, monosodium glutamate, penicillin for patients in hospitals, insulin for diabetics, etc.
