I used to be a freshman in high school, so I didn't know anything later, but then I found out that genetics is actually very simple, you first figure out the basic process, these have to be memorized, and there are some genetic laws to remember, and then do the college entrance examination questions all over the world, after doing some, you will find that you know how to do it when you see the questions, and I did well in the biology test in the college entrance examination this year、、、
-
There is no way to do the subject of biology, so I can only do more and memorize more. The genetic part is actually sometimes very interesting, as long as you are familiar with the three laws of heredity, and then do more, there will inevitably be a big problem in heredity in the college entrance examination, you can take some simple points, and the calculation of genetics is really annoying. But do more and you'll find the trick.
-
To master the study method, what I do is to organize my notes, and then streamline them, leave the test points and key points, and memorize more.
-
Listen carefully in class, preview after class, don't need a lot, just one class faster than the teacher's pace. The genetic part of the compulsory 2 in the second year of high school is mainly to understand the content of the book, practice more after class, and ask the teacher more if you can't, you don't have to worry, compulsory 2 should only account for one big question in the college entrance examination.
-
Preview before class, listen to lectures in class, look at notes after class to do questions, think more about it and summarize more, and form a knowledge system in your head.
-
It's also important to prepare for the lesson, so that you don't understand it completely in class.
-
In fact, I was also very poor in biology in my sophomore year of high school, but in the final college entrance examination, biology still improved very quickly.
I think science students must do a lot of questions, first read the textbook must have a lot of don't understand, it is recommended that you do the questions while looking for the relevant content on the tree, genetics I don't know if you are talking about dominant, recessive judgment, for the inner species to judge what chromosome the gene is on and the probability of genetic disease, this kind of question is a formula, and gradually you can feel the law.

1.Biology is a subject with heavy liberal arts attributes in science, so it is necessary to memorize more. Biology is a subject that correctly understands the body and learns the relationship between people and the environment (plants, animals, nature).
2 Don't memorize blindly, connect and understand with the experiences of life.
Application scheme. 1. Understand the content of the textbook carefully, understand and memorize the basic concepts.
2. Understand what you have learned in relation to real life.
3. Compare everyday language with scientific language, understand it and memorize it.
4. After expressing the content in a diagram or **, organize and understand.
5. After the experiment is organized, it is understood in connection with the concept.
6. Memorize the explanatory part of the study materials and the organized part of the workbook.
7. Memorize in different ways depending on the content.
8 Questions that you don't understand must be solved.
9. Confirm what you have learned by solving problems.
You can also sort out the questions you did wrong and focus on them before the next exam. If you don't understand the questions, check the textbooks and study materials to figure it out. Write the questions in the order of basic --- medium difficulty questions --- difficult questions to understand the content.
-
The most important thing is to memorize and do more basic exercises.
-
In the past, when I was studying biology, I followed the teacher's rhythm, listened carefully in class, did homework carefully after class, and asked teachers and classmates for advice if I didn't understand. Of course, you have to read more books, biology is a discipline between science and liberal arts, not only to do more questions, more to understand, but also to read more books, you have to learn a section to understand, a chapter to understand a chapter, so that you should be able to learn biology well, this is how I learned, and was selected by the teacher to participate in the biology Olympiad in Hunan Province. That's all I can help you with.
-
Biology is a liberal arts subject in science, and in addition to listening to lectures and doing exercises, the key is to read books thoroughly. Many of the small places in the book are inconspicuous, but they are important test points. Some small points can be made by knowing a point, and no point can be missing.
-
The focus of high school biology is to return to the textbook, nothing to take the book as ** to browse, the biology knowledge points are very detailed, and many small places in the book will be tested.
As for doing the questions, just look at the typical example questions, and your biology will be good if you can quickly mobilize your knowledge reserve when doing the questions.
Finally, you must be careful as an organism, many questions are very annoying, and traps are deliberately set.
-
Memory This is a fundamental skill of living beings.
-
Biology is a science subject, but there are a lot of things to memorize, and biology was okay when I was in high school. At that time, in addition to reading English and Chinese, I also memorized some biological things, such as the structure of cells and the effect of insulin. Be sure to memorize the knowledge points of biology clearly.
In addition, you also need to do questions to consolidate the knowledge points, so that you can grasp them flexibly.
When doing questions, you should master some answering skills, it is recommended that you go to Tianjin Xindong 51xdf forum middle school examination section of the high school all subjects to see, there are many new Oriental famous teachers summarized some chemistry learning materials and biology answering skills, I hope it will help you

Learning biology well is actually very simple, and I think the three physiognomy of biology are the easiest.
Remember that there are always exceptions to biology, and the exceptions are the easiest to get from the choice, so you should remember the "exceptions" mentioned by the teacher in class.
Books are very important, biology is the liberal arts in science, memorize more, and it is very simple to master its rules, just like chemistry is difficult to learn at the beginning, but it is relatively simple to basically memorize the elemental cycle and basic laws, when approaching the exam or the day before the exam, it is very important to look at the biology textbook, it is also very effective, and the Buddha's feet of temporary holding biology are more effective than any other course.
Homework should be revised in time, and questions should be asked in time, because some concept points are very easy to forget and confuse, when I was in high school, I wrote the knowledge points that were easy to confuse on post-it notes, and then pasted them on the pen holder, and it was easy to see it when I was in a daze every day, and my mind was full of post-it notes during the exam.
The topic selection of the topic is also very important, you will do the topic of that province in which province, because the textbooks of each province are different, try not to do the topic of other provinces, in case you can't do it, it will affect the mood, it is too easy and a waste of time.
Also, it is necessary to pay attention to current affairs, such as "melamine", "poisoned milk powder", "low carbon", etc., current affairs are easy to learn.
In general, I like living things more, because compared to those more rigid celestial elements, this kind of thing closely related to life always makes me feel kind, biology is not difficult to learn, I hope you like biology as much as I do, and finally, I wish you success.

First of all, you must not hate biology, the knowledge points of biology are relatively detailed, and you should listen carefully to the teacher's explanation in class and take good notes. Be sure to pay attention to the important points that the teacher is talking about. Textbooks are the key to biology, and it is best to answer questions in the original words of the book.
Do more exercises, and you will find that there are only a few knowledge points in the test, and summarize more. Many of the topics of biology are very loose, if you want to choose the wrong one, you will choose the most wrong one, and if you want to choose the right one, you will choose the most correct one. Experimental questions are the focus of biology, and it is necessary to learn through the experimental prototypes in the book.
The principles of each experiment are in the book, but the test points are different for each question. You should carefully read the question to understand what this question is tested, and think through the content of this question before answering. The revision time to the third year of high school biology is very long, so you can't feel irritated.
It is necessary to learn well in each period step by step.

Just work hard. Biology is a liberal arts within the sciences. There are more things that need to be memorized, just remember them carefully, as for the things that are counted more regularly, you will be able to go back to one, it is recommended to take notes, pay attention to the main thing that is not in the book.
In the end, I put together the things that I often can't remember, and look at them repeatedly, so that I will remember, and I am like this, and I feel that the effect is very good. In fact, biology is quite fun, and it is easier to learn than other subjects!
-
Remembering first memorizes the regularity and understands it.
Pay attention to the notes that the teacher summarizes.
If there is something unclear and you can't guess, you have to ask the teacher.
Creatures have a lot of unclear things, and they are easy to mess up.
The content of the textbook should be scrutinized word by word, and it is the test point.
That little creature in high school is indeed very shallow. And the genetics involved can be said to be a bit of popular science introduction. If you are really interested, buy a book on genetics and read it, and you will find out if you really like it. >>>More

First, the dominant recessive nature of albinism and sickle anemia was determined, and according to the left half of Figure 1, it can be concluded that anemia is a recessive genetic disease, which is bb; Then look at Figure 2, because if it is normal, it can be cut, and if it is not normal, it can't, so B is normal, C is albino, and both are homozygous, only A is heterozygous (because A can cut out three pieces: DNA is a double helix structure, only one of A can be cut, B can be cut all of them, cut into two short and two long, C is not cut) Because albinism is a recessive genetic disease, it is AA, so it can be known that B is AA and C is AA >>>More
