What Happened If You Didn't Take The College Entrance Examination? I Recommend

With more people, even the competition became fiercer, which put him under some pressure.

According to the guidance of the sign hanging on the street tree, Lu Shixian quickly found his competition seat.

According to the chatter of the contestants next to him, Lu Shixian soon felt relieved.

Because he actually came from a student from another county or city.

Based on this, everyone who participated in the 2008 preliminaries in Suzhou should be here.

Now, Lu Shixian is both happy and regretful.

I am happy that the pressure of competition has become less. Unfortunately, it is also a subject competition. Compared with mathematics, almost every prefecture-level city has a test center. Biology is too weak, and it is really not taken seriously.

But he can only sigh that he can't change anything now.

Lu Shixian's attention was quickly attracted by the voice of the invigilator announcing the discipline of the examination room.

Finally, the test papers for the biology competition were distributed to him.

Lu Shixian began to concentrate on the test paper in front of him.

But with just a glimpse, Lu Shixian immediately judged the outcome of the test paper in front of him.

It seems that the grade is not good enough.

Question 1: What are the characteristics of facultative heterochromatin?

Do you even need to think about it? Presumably all high school students know it.

It is obvious that b can be transcribed when the chromatin is loose.

Soon he looked to the second part, the first question was the type of placenta that the pistil that forms the capsule has.

I feel a little confused if I haven't learned about placenta, but as long as I read "Botany", what brother?

Axial placenta, special central placenta and parietal placenta.

Is there anyone who can't do it?

Lu Shixian is like taking a walk in the garden, constantly in a state of self-doubt and suspicion of who is involved.

Too simple, right? Is this the preliminaries? Could it be that the water is released this time?

After finishing, Lu Shixian couldn't help but looked up and looked around, and he was still working hard.

Lu Shixian had to sigh in his heart that biology is really different from mathematics. If you can't do mathematics, you really can't do it, so you simply gave up.

But biology is a multiple-choice question, isn't it just choosing abcd?

Even if you choose blindly, you still have a chance to do it right!

If they get it right, they might even enter the league.

With such a fluke mentality, who is willing to give up lightly.

Lu Shixian shook his head, seeing that the time was almost up, and signaled to the invigilator to hand in the test paper early.

He put away the examination tools and found his schoolbag in the centralized storage area.

Carrying a small schoolbag, Lu Shixian left leisurely under the envious eyes of the rest.

When you come, you are alone, and when you leave, you are alone.

He alone represents the entire vitality of Jinling No. 1 Middle School.

On the way back, the entire bus was basically filled with students who participated in the biology competition.

The discussion in the car was a lively one, as if it had directly turned into a live discussion meeting.

Suddenly, a girl sitting in front of Lu Shixian asked: "The second part, in the life history of algae, is the answer to the alternation of alien generations with spores dominant?"

"I see that the other three answers don't have the word algae, so it's obviously polycystic algae. They also ask this kind of question? Isn't it a waste of time?"

As soon as this remark came out, Lu Shixian immediately covered his face and didn't know what to say?

This is to treat the examiner as a fool.

However, to his surprise, many people started to agree.

This is outrageous!

To Lu Shixian's relief, fortunately, someone questioned it.

"You are wrong. Do you think the teacher will make it so simple?"

"I don't know if you've heard a saying that the most dangerous place is the safest place. I read a biology science book before. It said that water clouds and Ulva are algae, so the final answer is either a water cloud or a d-stone water shield."

As soon as this remark came out, the boy who spoke immediately got admiring eyes from the girl.

Seeing this situation, Lu Shixian was really speechless.

Hey guys, these guys are correct answer removers.

Originally, Lu Shixian didn't intend to get involved, but in order to save the ignorant girl and defeat the big villain.

Lu Shixian couldn't bear it anymore, and gave them a correct science introduction.

"In the life history of most brown algae, there are obvious generation alternations, both heterogeneous and homogeneous."

"The same type of generation alternation means that the sporophyte and gametophyte are similar in shape and size, such as the genus Shuiyun. The heteromorphic generation alternation means that the shape and size of the sporophyte and gametophyte are very different. Most species have more developed sporophytes, such as c-answer kelp. "

"The Polytubella you mentioned belongs to the red algae, and the Ulva belongs to the green algae, and they all alternate generations of the same type."

Now the boy immediately showed an embarrassed expression, while the girl looked at Lu Shixian with admiration.

"You are so good! I feel that I have to rely on Mongolia for many of the questions. If only I were as good as you!"

And suddenly there were many wailing voices in the car. Lu Shixian was also a little embarrassed, and he assured that he really didn't intend to interfere with that guy's pretend process.

But the process by which they got the answer was too outrageous. In the heart of spreading the truth, Lu Shixian felt that he should not let them fall into the quagmire of lies.

But I didn't expect that boy just now to be a little unconvinced.

"It seems that you have read some books. If you can tell the correct answer to this question, Chen Chen, my No. 2 middle school, will convince you."

Lu Shixian smiled wryly. He really didn't intend to create a plot of pretending to slap his face. At his level, it's a bit embarrassing to care about people in this kind of qualifying competition.

But before he could refuse, the boy had already read out the topic.

"The total variance of a random mating line is 1461, while the variance of a homozygous inbred line is 0867, and the narrow heritability h2 is 38%. Do you know the answer to this question?"

I have to say that this boy still has a bit of eyesight, and this set of questions is definitely the finale of this set of preliminaries.

Not only does it appear in the fourth part, which is the most difficult, testing knowledge related to genetics, but it is also a multiple choice.

Combining the two, the difficulty is not small.

Unfortunately, for Lu Shixian, this topic is only an introduction to genetics.

Will the face stretched out in vain be hit or not?

Is this relatively low-level force pretending or not?

Lu Shixian thought for a while and finally succumbed to reality. After all, if you don't fight for nothing, you don't fight, and if you don't pretend, you don't pretend.

"If I remember correctly the total variance is p is 1461, the variance of the homozygous inbred line is q, the narrow heritability is h2, the environmental variance e is 0867, the dominant genetic variance d, the additive genetic variance a, the broad genetic The force h2 is 38% of the total genetic variance g."

"Then the percentage of the environmental variance of option a to the phenotypic variance is q/p=0867/1461, which is exactly 593%."

"The percentage of dominant genetic variance to phenotypic variance h2=d/(d+e), if you solve an equation, you will know that the answer is not option b 38%."

"So the final answer is acd."

In fact, as early as when Lu Shixian mentioned the reason for the wrong answer of b, that boy's unruly energy had already been tamed.

Students who can participate in the student competition are at least not pure whites. With such a detailed explanation by Lu Shixian, they naturally understand whether Lu Shixian is correct or not.

They even feel that the answering process is more detailed than their coach.
