Luxury Trial Marriage: Scandalous Wife Don't Try to Escape

Class passed quickly one by one. In her spare time, there were naturally people sitting next to Xi Lexin's seat to chat. Naturally, there are also people to help, which poetry pocket booklets are convenient for her to recite and so on.

Xi Lexin naturally did not refuse, and everyone else cared about her study. After all, with half a year left, it's really a little difficult to catch up with the college entrance examination. Xi Lexin just hopes that she doesn't hold back the class. She doesn't have to be the best.

Xi Lexin expressed helplessness about her current learning progress. The people in the class began to review very early. They have been reading since the second year of senior high school. In fact, most of the time in the third year of senior high school is reviewing.

Therefore, Xi Lexin thought of the problems she would face next. Really is a sense of weakness!

Soon, the biology teacher came to give a lecture. The most common thing in grade three of senior high school is continuous exams, a big exam in three days and a small exam in two days.

The first class is naturally about the test paper. Xi Lexin looked at this time. Asked the teacher some questions, it is natural to start from the chromosome.

The biology teacher was very outspoken and talked about the differences between men and women. There is also the origin of the moon (harmony) event and the legacy (harmony) essence, which is very explicit and makes Xi Lexin blush.

Is the biology teacher molesting Xi Lexin and giving her the first class. Running on this topic, Mo Xiangchen sat behind and frowned.

"Teacher, come here for a minute." Mo Xiangchen hurriedly called the male biology teacher over. Don't spoil Xi Lexin's ears.

"What's the matter? Should Mr. Mo also study?" obviously, the male teacher is in a good mood. "Yes! I just met a problem. Should the teacher solve it?" Mo Xiangchen said something provocative.

All the students who reviewed looked up at Mo Xiangchen, a handsome man who didn't talk much after three classes.

"Oh! What's the problem?" the biology teacher naturally came over confident.

Mo Xiangchen said carelessly: "When cutting purple backed sunflower, pay attention to control the ambient temperature and humidity and have sufficient light; when cutting the stem segment, the upper incision is horizontal and the lower incision is oblique. According to your practice and the material analysis given, why is the upper incision horizontal and the lower incision oblique when cutting purple backed sunflower?"

(Note: This is the title searched by Baidu.)

Mo Xiangchen finished the provocative meditation, because this topic is not in the textbook at all.

"What?" the biology teacher didn't understand it. Generally, if you have words, you can also study it, but it only depends on listening.

But it was a little difficult, "where am I reading it once." Mo Xiangchen repeated silently again, "how? Does the teacher hear clearly?" Mo Xiangchen made it clear that he was trying to put pressure on the biology teacher.

Xi Lexin was amused. She picked her sword eyebrow and thought of what the teacher had just said. Looking at his appearance now, Xi Lexin's anger almost disappeared.

"Cough, because the level of the upper incision is to meet the normal distribution of auxin and make the plants have directional light characteristics. The oblique direction of the lower incision is to increase the surface area of the incision and absorb more water." (Note: this solution is the answer searched by Baidu.)

The biology teacher reluctantly said the answer. Mo Xiangchen didn't think that this question could embarrass him. However, it's impossible to let him go.

"The reason of" upper flat "is to reduce the excessive evaporation of water in the wound, and the reason of" lower inclined "is to increase the area of water absorption. The cutting of purple backed Tiankui belongs to tender branch cutting, which needs photosynthesis to produce nutrients and sufficient water to promote rooting. The stem nodes of purple backed Tiankui are prone to adventitious roots," upper flat and lower inclined " "The resulting healing tissue is large and can take root. At the same time, the materials cut out in this way can easily identify the positive and negative directions, so as not to insert them wrongly."
