Correct answer: BC

Biotechnology is the technology that uses (living organisms, biological activity processes) to obtain products and serve human beings.

Biotechnology refers to the use of "organisms (including animals, plants and microorganisms)" to produce useful substances or improve the characteristics of organisms, so as to reduce costs and innovate species. Carry out a technology in different fields such as human medicine, environment, agriculture and food.

With a rapidly expanding population, the issue of food is the entry point for biotechnology applications. Under the development of genetically cloned crops, in addition to cloning genes for insect pests and frost resistance, rice containing vitamin A has also been introduced.

With limited arable land, crop cloning solves the problem of quality. In addition, ornamental flowers are also reproduced and produced by tissue culture technology to increase the value of high-quality flowers.

The famous one is Taiwan's Phalaenopsis orchid. In addition, cows that have been genetically engineered to produce clotting factors are also available for medical purposes. Raw Bimin resistant fertilizer.

The type of fertilizer that is mainly made using microbial technology. Biological fertilizer not only provides nutrients for crops, improves quality, enhances cold and insect resistance, but also improves soil permeability, water retention, pH and other physical and chemical characteristics, which can create a good growth environment for crop roots, so as to ensure the increase of crop yield.

Biopesticides are pesticides made from microbial strains with strong virulence by using microorganisms, antibiotics and genetic engineering to produce toxins that have the effect of killing insects and diseases.

Research in this area has received great attention. For example, stem cells are used in the field of regenerative medicine, such as artificial organs, nerve repair, etc. Or use the protein structure analysis data to develop corresponding inhibitors for functional regions (e.g.,

enzyme inhibitors). Use microarray nucleic acid chips, or protein chips, to find disease-causing genes.

Or using antibody technology to deliver toxins to cancer cells with special markers. Or use gene cloning technology to enter the cavity to carry out genes**, etc.

Genetherapy is a new technology born from the combination of modern medicine and molecular biology by using molecular biology methods to introduce the target gene into the patient's body and express the target gene product, so that the disease can be obtained. As a new means of new diseases, genes have brought light to some intractable diseases.

The saw is designed to mimic a jagged plant.

The plane imitated the Bird (wings, streamlined body).

Biology is a science that studies the structure, function, occurrence and development of organisms (including plants, animals and microorganisms), and is a part of natural science. The aim is to elucidate and control the activities of life, to transform nature, and to serve the practices of agriculture, industry, and medicine.

Taxonomy is the branch of biology that studies the methods and principles of taxonomy. Classification is to follow the taxonomic protonormal tolerance and methods to name and rank various groups of organisms. After the Swedish biologist Linnaeus named the organisms, later biologists classified them by domain, kingdom, phylum, class, order, family, genus, and species.

The uppermost realm, the Five Realms proposed by Waittaker, is more accepted by many people; They are the prokaryotic kingdom, the protist kingdom, the fungal kingdom, the plant kingdom and the animal kingdom. Starting from the "boundary" at the top to the "species", the lower the level, the more similar the characteristics of the creatures to which they belong. There are seven categories, which are:

The application of biological characteristics has been widely used in many fields, from medicine to food science to environmental protection and engineering. One of them is the application of biological properties to materials science, using the specific characteristics possessed by living organisms (such as strength, toughness, breathability, water resistance, semiconductor properties, etc.) to develop new products. Here are some examples of biometric-based products.

First of all, a common example is the use of spider silk to make materials for high-strength fibers. In spider silk, the silk proteins are arranged in a certain regularity, forming a material with high strength and toughness. Several laboratories are investigating the use of this resilient and lightweight material in lightweight vehicle components, sporting goods, and military equipment.

Secondly, the surface nanostructure of the insect body provides natural waterproof and antifouling properties. Some companies use these properties to create water- and anti-stick coatings that can be used in both indoor and outdoor environments, such as furniture, electronics, and building materials.

Thirdly, sumac is a tree species that can deform and self-heal. These properties come from its special tissue structure and chemical properties. Some researchers are trying to apply the self-healing properties of the lacquer tree to plastics that can extend their lifespan without the need for manual repair.

Another example is bioporous ceramics. By using living organisms as templates, scientists can create ceramic materials based on them. These porous ceramic materials can be used in many applications in the medical and environmental fields, such as bone implants and water treatment over-destruction filters.

In short, the development of new products using biological characteristics is an important field of modern science and technology. From high-strength fibers to self-healing plastics to ceramic materials, the wide range of applications of these products demonstrates the potential of biological sciences for the development of human technology. <>
