How to review biology in the second year of junior high school to achieve A?

I don't think there's a trick but rote memorization, and biology in junior high school is all knowledge, unlike high school, which has to be analyzed, so it's no problem to memorize it.

It turned out that in the class next door to us, their homeroom teacher was a biology teacher, who stuck people at the door all day long, and could only enter the class by memorizing them, and asked questions in different ways, and the biology in their class was the best in all classes. It's not just about memorizing the blank ones in the exercises, but you have to memorize all the questions, because you don't know which knowledge point to fill in the next time, you can dig a blank in another place for you to fill in.

Just practice more! My former teacher bought a lot of exercises! If you don't understand, just ask! That's it!

The knowledge points of biology are very fragmentary, you need to look at it carefully, you don't need to memorize it, but you need to accumulate bit by bit, I am a biology major, and I have a particularly deep experience in this aspect. When I was in high school, I didn't know how to learn biology at first, and I heard others say that creatures have to memorize, so I memorized, and finally the more I studied, the more I died, and I became more and more incomprehensible. Then I took my own interests and ideas to learn, and slowly became interested.

Now, I like to learn biology very much, I love some new things about biology, I suggest you also learn with curiosity and interest, if you don't like it, just for the exam, then, I think as long as you read more biology books, look at the knowledge points, do more to do a variety of body types, biology questions are regular. The concept of genetic engineering is based on molecular genetics as a theoretical basis, with the modern methods of molecular biology and microbiology as a means to construct hybrid DNA molecules in vitro according to the pre-designed blueprint of different genes, and then introduce them into living cellsto change the original genetic characteristics of organisms, obtain new varieties, and produce new products. Genetic engineering technology provides a powerful means for the study of gene structure and function.

Genetic engineering is a common method, several new concepts such as what restriction enzymes do, what do they do, the basic process of genetic engineering, and the purpose of extraction is to Jingpeng genes.

Combination of target gene and carrier Introduce the target gene into the recipient cell Detection and expression of the target gene, etc., first read the book to form a network of knowledge points, then do questions, summarize the knowledge points obtained in the common test, and finally, you can put the book together, echo those knowledge points in your mind, list the large framework on the paper, and then, recall a large number of knowledge points behind the large framework. I think that having said so much should help you, if you don't know it, you can ask again.

It's not difficult to be a creature in the first year of junior high school.

The sou Ling of the world rock relatives in the jujube book is familiar with it.

And the teacher in class to supplement all the good to understand.

Cook the melon on the back of the biology book, and then make a mock volume.
