Give some of the mistakes in high school biology?

I summarized the biology compulsory 1 1, the most important thing in the theory is respiration and photosynthesis These two processes must be clarified, and it is easy to make mistakes in the combination of the two questions in the answer For example, the abscissa is the light intensity The ordinate is the amount of CO2 The turning point is that the rate of the two is equal The decreasing image is that photosynthesis is greater than respiration In particular, it should be reminded that when calculating the rate of photosynthesis, do not forget the amount of CO2 produced by respiration 2, and it is easier to make mistakes in the reagents and operations of the experiment. Microscopic observation.

Compulsory 2 1. The conclusion of Mendel's laws of inheritance should be kept in mind Multiple choice questions often change some statements slightly 2. Scientists and related operations and conclusions of transformation experiments such as pneumococcus must be remembered Exams are also prone to some questions here 3. Genetic questions, one of the most difficult questions in high school biology, comprehend more 4. Concepts of heritable variation such as gene mutation and chromosomal variation.

Compulsory 3 1, the process of nervous, humoral and immune regulation is often examined, and it is easy to make mistakes, so it must be kept in mind 2. The development process of plant auxin, the experiments and conclusions made by scientists must be kept in mind, and the multiple-choice questions often appear 3. The concept of ecosystem, community, and population, the distribution map of judging the interspecific relationship of organisms, and the analysis of material circulation and energy flow in biological communities are all very important.

Electives, just write them down, there's nothing easy to make mistakes.

After reading your question, I thought about it for the time being, but I may not be thoughtful, but I will make up for it when I think about it later, and I will give a point first.

In chemistry, the amount of matter is not very well understood by many students when they first learned it, but it is actually a new unit of measurement, which is introduced to better represent the quantitative relationship between molecules and surfaces between substances.

I dismantled the Chang Ji Zheng Zhen knot.

Biology Compulsory 1.

1. The most important thing in the comprehensive is respiration and photosynthesis.

These two processes must be clarified, and.

It's easy to get a combination of the two questions wrong.

For example, the abscissa is the intensity of the light.

The ordinate is the amount of CO2.

The turning point is that the rates are equal.

The decreasing image is that photosynthesis is greater than respiration.

In particular, when calculating the rate of photosynthesis, do not forget the amount of CO2 produced by breathing.

2. It is also easy to make mistakes in the reagents, operations of experiments, and observation of microscopes.

Compulsory 2. 1. The conclusion of Mendel's laws of inheritance should be kept in mind.

Multiple-choice questions often change a little bit.

2. Scientists and related operations and conclusions of transformation experiments such as Pneumococcus must be remembered.

Exams are also prone to some problems here.

3. Genetic questions, one of the most difficult questions in high school biology, comprehend more 4, genetic mutations, chromosomal variations and other concepts of heritable variation.

Compulsory 3. 1. The process of nervous, humoral and immune regulation is often examined, and it is easy to make mistakes.

2. In the development process of plant auxin, the experiments and conclusions made by scientists must be kept in mind, and multiple-choice questions often appear.

3. The concept of ecosystem, community and population, the distribution map of judging the interspecific relationship of organisms, and the analysis of material circulation and energy flow within the biological community are all very important.

It's good to take electives.

There's nothing error-prone.

Look at your question.

I may not be thoughtful about this for the time being, but I will make up for it when I think about it later.

Let's give a point first.
