There are too many general biology knowledge points, and there is no general structure, how to revie

You can borrow the syllabus of the previous session and ask the teacher again, biology is like this, you need to understand and memorize.

I feel that biology is like common sense, you don't know, the question can't be done at all, it's not too important, maybe the teachers in our class are picking up the key points, and they have told us I feel that the knowledge points of these three or four books are not particularly noisy to consolidate a few more times, and to memorize more, maybe what questions will be used, and you think it's not an important place to accompany the brother.

Biology should be the least difficult subject of all the subjects in high school. There is no need for Fan Sen to memorize, there are only not many biology textbooks, and the teacher will often repeatedly mention the key knowledge in the past three years.

Oh, you look at the table of contents first, see the more similar ones put together, build a framework, the framework is set up, you have to straighten out your own ideas, in fact, blindly reading is useful, there must be a cascading and progressive idea, so it is easy to remember! Sharpen the knife and do not mistake the woodcutter. Good luck with your exams!

Ha! I'm also in the second year of junior high school!! The difficulty of the biology test depends on where you are – the questions are generally easy in metropolises, but more difficult in second-tier cities!

I am from Weifang, the second most difficult !! in the country If you score 40 points in two rolls (or one volume), it's okay, spell it out! A very possibility!

Mainly review seven times, and take a look at all eight!

Feel biology, do more questions, more than the combination of examples in life, so easy to remember, understand!

There shouldn't be much to memorize about biological knowledge, so don't mistake it for the "liberal arts" in science.

It is important to understand that cells, metabolism (cellular respiration, photosynthesis), genetics, ecology, evolution.

Modern bioengineering several large blocks.

A good way to do this is to master the classical experiments and summarize the general thinking of the experiments... High school biology is mostly memory...

Definitely, because it is related to sex, it is generally necessary to write male and female even if it is not inherited with sex.

The parent is linked by two lethal genes, and the two genes exist in an expulsive form. If both the dominant wing-wing gene cy and the dominant astrophthal-eye s have recessive lethal genes, they exist on the second chromosome in an exclusive form. Such individual hybridizations will have the situation you mentioned.
