What to do I have a very bad Biology Compulsory One

First of all, you can calm down, don't worry, you can first read some things about biology, cultivate interest, biology must first learn the cell structure, from the outside to the inside, the cell membrane, cytoplasm, nucleus, the structure and function of each organelle must be clear, don't read the book to do more questions, don't look at the answer, but find the answer in the book yourself, and then the answer to the workbook, if you don't understand, ask the teacher, don't be embarrassed, hehe, come on!

Biology is still a bit of a liberal arts, there are a lot of just need to memorize, it is recommended that you buy a better teaching aid, such as guidance and practice, combined with the teaching assistant to summarize the knowledge of memorization will save effort, and the title of this book is fully analyzed. If you don't understand the analysis, ask the teacher.

Compulsory 1 doesn't seem to be very difficult, but if you are a science student, you must do biology well, because biology and chemistry are relatively simple subjects in science. Believe in yourself, one knowledge point at a time, you will definitely be able to.

Biology is very simple, as long as you read more books, just the points are in the book, usually when you have nothing to do, read the book a few times, and there is also a question that you have done to see, understand which is just the point it asks, what kind of question type each knowledge point has, their question ideas, and then summarize the problem solving ideas, you must strive to know the other so far, in order to be invincible!

Focus on methodology. Strengthen the establishment of knowledge linkages. Don't memorize.

The key to biology is to practice in memory, memorize in practice, and think more about what knowledge points in the textbook are used when doing problems. This is good for problem solving, and it is also good for mastering knowledge points.

First of all, you have to be interested, in fact, biology is quite interesting, closely related to human physiology, and worthy of study. It is much better to listen to the teacher's lectures more often. Compulsory 1: I'm pretty good at it.

Biology is still very simple, patiently memorize it, and ask the teacher more.

Pay attention to classroom learning and organize class notes! Do more exercises.

It's a bit like liberal arts to memorize but also to understand in moderation.

Compulsory one is the foundation of high school biology, mostly memorization knowledge, it is recommended to read more books and teachers' notes in class, combined with exercises to master, in short, if you don't want to make up the class, then you have to work hard.

Read the book thoroughly and read the textbook.

Summary. Of course, as long as you have enough patience and perseverance, you can make up for the content of Biology Compulsory 2. First of all, you can consult relevant books and materials, read carefully, grasp the key points, figure out the content of each chapter, and understand every knowledge point.

Secondly, you can do some practice questions, practice every knowledge point once, and grasp every knowledge point firmly. Finally, you can discuss with your teacher or classmates to answer your doubts and make up for your shortcomings. As long as you persevere and understand every knowledge point, you can make up the content of Biology Compulsory 2.

Of course, as long as you have enough patience and perseverance, you can make up for the content of the second compulsory course. First of all, you can consult relevant books and materials, read carefully, grasp the key points, figure out the content of each chapter, and understand every knowledge point. Secondly, you can do some practice questions, practice every knowledge point once, and grasp every knowledge point firmly.

Finally, you can discuss with your teacher or classmates to answer your doubts and make up for your own inattention. As long as you persevere and understand every knowledge point, you can make up the content of Biology Compulsory 2.

Fellow, I really didn't understand, I can be more specific.

Can I make up for the second compulsory course in biology? Answer: It's a pity that I can't make up for the second compulsory course in biology.

Biology field bench is a discipline that involves a lot of knowledge, and a large number of knowledge points need to be mastered in the learning process, and there is a close relationship between these knowledge points, so learning biology needs to be persistent, step-by-step, and cannot skip grades. Workaround:1

Strengthen learning: If you want to make up for the second compulsory course of biology, you must first strengthen your learning, grasp the rhythm of learning, learn step by step according to the knowledge points of the textbook, do not skip grades, and have a firm grasp of every knowledge songsail travel point. 2.

Ask for help: If you still can't make up for the second compulsory course of biology by yourself, you can seek help from teachers or parents, you can talk to teachers or parents about the problems encountered in learning, and you can ask teachers or parents to guide you in learning and help you learn biology better. Personal Tips:

1.Insist on learning: Studying biology requires perseverance, insisting on learning, grasping every knowledge point firmly, and not skipping grades to learn and study.

2.Strengthen memory: Learning biology requires mastering a large number of knowledge points, strengthening memory, practicing more, consulting more information, summarizing more, and remembering every knowledge point.

3.Ask for help: If you encounter problems in learning, you can seek help from teachers or parents, and you can ask teachers or parents to guide you in learning and help you learn biology better.

High school biology is a special subject for many students, many students said that they could understand and memorize after class, but their grades were still a mess in the exam, and a very important reason for this is that many students do not summarize. We are in class, and the knowledge points in middle school are all single-faced, but the content of the exam requires us to integrate the knowledge points, so if we don't make a summary, we will suffer very much. The content of the whole book in compulsory course 3 includes neuromodulation, humoral regulation, ethnic community ecosystem, etc., and relatively speaking, the knowledge points in this part are relatively simple.

These knowledge is very easy to understand, but the details of the exam are very delicate, as a science subject, compulsory three fully embodies the precise concept, even if you know the meaning of the question, if you can't directly express the original words in the book, it is likely to be wrong.

What are the mistakes in Compulsory 3?

First of all, we all know that our tears, sweat, and digestive juices are not part of the human body's body fluids; For the human body, the stability of the pH value is very important, and the pH value is too large or too small will have a certain impact on people; In addition, if you secrete too much growth hormone, you will have gigantism, and if you secrete too little, you will get dwarfism; If you don't have enough insulin, you will develop diabetes. After the target cells are destroyed, the virus in the body cannot hide, and it is destroyed by the body.

How can we reduce the error rate?

Given the current format of exams, questions are becoming more and more flexible, so rote memorization is no longer a good way to do it. It is only through understanding and memorization that we can integrate the knowledge we have learned. However, it is important to remember that all the questions are in the textbook, and we can only consolidate the questions if we learn the textbook knowledge well, and the effect of blindly doing the questions is not obvious.

Mistaken knowledge is likely to occur, including the secretion of cells, the environment in which cells live, metabolites in tissues, the composition of tap water, the main components in cells, and the digestive tract.

The water content of the human body, the internal fluid of the cells, the osmotic pressure, the pH of the plasma, the cerebral cortex, these are all very easy places to go wrong.

Ethnic community ecosystems, humoral regulation, neuromodulation, plasma pH, and cytology are all very error-prone points.

Requirements and Methods for Studying Biology:

1.To learn biological knowledge, it is important to understand and think diligently.

2.It is necessary to pay attention to understanding the process and methods of scientific research, carefully conduct observations and experiments, and pay more attention to understanding the world.

3.It is necessary to attach importance to integrating theory with practice.

In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own learning method. Good luck with your studies!

Biology compulsory one is a more basic part of high school, you can do more questions to better understand the content of learning, and read more books after class, it is best to be able to memorize them.

You can learn how you want to learn.

In fact, high school biology is not difficult, and many things to memorize must be understood to understand the reason, so it is not difficult to remember.

Then there are a lot of pitfalls during the exam, so be sure to review the questions clearly.

The first compulsory course is very simple, it is an introduction to biology, you can memorize it, and there are not too many knowledge points or anything, you can focus on other classes, and biology is simply listening.

Compulsory 1 is very simple, biology is the liberal arts in the sciences, and geography is the science in the liberal arts.

Just listen carefully in class, and complete the homework by thinking independently.

If the first category in the diagram represents a large category, and the following common categories are examples, then ......Completely wrong.

It's a wrong format, right?).

Monosaccharides: common to animals and plants: glucose, deoxyribose, ribose.

Plant: fructose.

Animal: Galactose.

Disaccharides: Plants: sucrose, maltose.

Animal: lactose.

Polysaccharides: Plants: starch, cellulose.

Animals: glycogen - liver glycogen, muscle glycogen (and a small amount of nerve glycogen) [carbohydrates are the main energy substances in living organisms].

The most important monosaccharide: glucose.

Disaccharides and polysaccharides that can store energy: disaccharides - sucrose, lactose; Polysaccharides - starch, glycogen structural sugars: ribose - composed of nucleotides and ATP; Cellulose – makes up the cell wall of plants.

Is deoxyribose an important energy substance?

It should be genetic material.

1 Sugars that can be oxidized to act as reducing agents.

2The chemical process by which a compound is cracked into two or more simpler compounds. The H and Oh moieties of the water molecule are involved in the reaction on either side of the cleavaged chemical bond. For example, fats are hydrolyzed under the action of acids, alkalis, and lipases to form glycerol and fatty acids or smaller molecules.

Hydrolysis is a chemical unit process that uses water to break down substances to form new substances. The ions ionized by salt combine H+ and OH- from water to form a weak electrolyte molecule. The reaction between a substance and water that causes the decomposition of a substance (not necessarily a metathesis reaction) can also be said to be whether the substance reacts with hydrogen ions or hydroxide ions in the water.

3. Sugar: monosaccharides can not be hydrolyzed, and disaccharides can be hydrolyzed into the monosaccharides that make up him, such as sucrose hydrolyzed into a molecule of glucose and a molecule of fructose, and polysaccharides are divided into animals (glycogen) and plants (starch and cellulose), which are all glucose after hydrolysis.

Fat: Preliminary hydrolysis into glycerol and fatty acids, and final hydrolysis into C, H, O, and some N, P

Protein: Initial hydrolysis into amino acids, final hydrolysis into C, H, O, N, and some contain P, S

DNA: Preliminary hydrolysis to deoxyribonucleic acid, final hydrolysis to deoxyribose, phosphoric acid, bases (A, T, G, C).

RNA: Preliminary hydrolysis to ribonucleic acid, final hydrolysis to ribose, phosphoric acid, bases (A, U, G, C).
