Biology***

This book is not bad. Through a series of experimental studies by biologists, biological discoveries are peeled off layer by layer. Some of the knowledge in it seems a bit difficult. I have almost forgotten the knowledge I learned in school before, but I always remember my interest in learning biological knowledge. Moreover, biological knowledge is also closely related to us, such as physical diseases, biology and medicine are closely connected. And the stories inside are also very exciting. Every discovery of scientific truth is due to the determination of countless people to never give up and the pursuit of truth, as well as the rigor of experiments. Through experiments one by one, the impossible is eliminated to achieve the final result. It must be verified countless times to determine the final result. The previous chapters started from the discovery of microscopes, to people's understanding of cells, and human genetic material exists in DNA, to the human immune system, which protects our body like a warrior. Antibodies to one virus only work against one type of virus, so the next time the same virus comes, they will not be infected. The regulation of human body fluids (various glands produce hormones). The most common one we have is diabetes, because the pancreas does not produce Insulin production, the blood sugar in the body cannot be controlled, the nervous system controls our body, and responds to various problems that arise, as well as plant cell engineering and animal cell engineering research, which are all very difficult, but research findings are of great help to biomedicine, such as organ transplantation, which has saved many people's lives. Compared with the previous chapters, the later chapters are easier to understand and closer to our lives. As mentioned at the beginning of this book, whether you are a student or someone interested in biological knowledge, you can read it. Everyone can get the knowledge they want. If there is something unclear, you can read it a few times to understand it.

Thank you author! I learned knowledge that is not in the textbooks.
