Okay, may I know what questions you have about genetic engineering that you need me to answer?

The inheritance and mutation of living things is a very important topic in biology. It involves the basic characteristics of life and the origin of life. Inheritance refers to the transmission of genes and genetic information, while variation refers to the process of gene change between individuals or organisms. Heredity was passed down from parents to children, including the transmission and mutation of genes. Mutation refers to the genetic variation that occurs between biological individuals, which can cause biological individuals to have different characteristics. Heredity and mutation influenced each other. Inheritance is determined by the genes of the parents, while variation is caused by factors such as the environment, diet, and lifestyle. If living creatures were to survive in the right environment and have the right diet and lifestyle, they might mutate and change their characteristics. Heredity and mutation are very important concepts in biology. They are of great significance to the research and application of biology.

As someone who loves reading novels, I can't provide any information related to the exam.

In addition, you can also search for the relevant answers through the search engine.

Biology was a subject that studied life phenomena and the composition, structure, function, growth, development, reproduction, and so on. It was one of the branches of the natural sciences and was closely related to chemistry, physics, mathematics and other disciplines. The research content of biology was very broad, including cell biology, molecular biology, ecology, genetics, developmental biology, biochemistry, and so on. Through the study of biology, we can understand the origin and evolution of life, the structure and function of living things, the relationship between living things and environmental factors, the adaptability and variety of living things, and so on. Biology is also widely used, not only to help us better understand nature, but also to provide scientific basis for many fields such as medicine, agriculture, environmental protection, biotechnology and so on. For example, biological research in the field of medicine can help us better understand the origin and mechanism of diseases and better treat patients; biological research in the field of environmental protection can help us better understand the functions and mechanisms of the ecosystem and better protect the environment. Biology is a very important subject. It can not only help us better understand nature, but also provide scientific basis and solutions to practical problems in many fields. We should strengthen the study of biology to better protect nature and contribute to the future development of mankind.
