Ranger freely walked through the Sheep, the competition team, the competition team, and the competition team was wearing it, and he went to the competition team.

Lei Tiangang, the head coach of the Shengjing team, originally refused to accept Lanjie, but as he refused, he also accepted it.

"Langjie, the last row of seats closest to the window in the Shengjing classroom is yours. You can come or not come for the Shengjing theory class. But when the coach is in class, you are not allowed to suddenly break in or leave. Can you do it?" Lei Tian had just given up to this level, so he was very tolerant, or even compromised.

Ranjie promised with confidence: "Yes, I can! Thank you Teacher Lei!"

Lei Tiangang said again: "In terms of student competition theory, I will give you all the information. If you can take theory classes, try to take theory classes. If you lack theory classes, learn the materials yourself. If you have any questions you don't understand, ask the coach. In terms of student competition experiments, I hope Ranjie, you don't miss any experimental practice class."

Teacher Lei’s plan was exactly what Ranger wanted, and Ranger said with great fighting spirit: “Received!”

This morning, there was Lei Tiangang's theory class. Lanjie came to the Shengjing classroom and took his designated seat to listen carefully to Teacher Lei's theory class.

Animal behavior is a national final and a must-have content for ibo. Lei Tiangang's class specializes in animal behavior: "Most new bees are worker bees, and the bee colony will also breed a small number of drone bees. Please think about a question: Who is controlling the gender of new bees?"

A classmate answered without hesitation: "It's the queen!"

Lei Tiangang asked: "Oh? Why?"

The classmate said confidently: "When a queen is married, she will store enough sperm that it will use for the rest of her life. The queen can control fertilization as she wishes. Which eggs the queen wants to fertilize, then it controls the sperm stored in the body to fertilize these eggs, thereby cultivating female bees and drones. Some larvae have been feeding on royal jelly after hatching. They have fertility after adulthood and become new queens. Why do larvae that have been eating royal jelly develop into queens instead of worker bees? Then I don't know, it's quite mysterious."

Lei Tiangang nodded and said, "Yu Junjie, you have a complete range of knowledge, a certain depth, and have your own thoughts in it. Do other students have other opinions?"

"Yes!" Ranjie couldn't wait to raise his hand.

Lei Tiangang looked to the corner of the back row: "Langjie, talk about your point of view."

Ranger was full of exploration of nature. He began to study the academic document "100,000 Whys" since he was three years old.

Ranger is very interested in mysterious creatures or common creatures' mysterious behaviors and has done some academic research. He said: "The queen bee uses simple methods to control the gender of the egg. This explanation is relatively simple, but the fact is not that simple."

"Hmm?" Yu Junjie smiled slightly, and he wanted to hear what Lanjie had.

"I have watched a documentary. There is a passage in the film that I remember deeply. Several worker bees ate the hatched drone, and the queen was shivering on the side. This shows that the boss in the bee colony is not the queen, but the worker bee." Lanjie made a move to wipe his neck, which was a bit arrogant, but in line with the meaning of the question.

Yu Junjie shook: "So cruel?"

"Then I continued to study documentaries, and then the worker bees kept eating. They not only ate the drone larvae, but also ate all the drone eggs."

"!"

"The nest of the drone is larger than that of ordinary nests. The queen can only cultivate drone in such large nests. Worker bees have no reproductive ability, and egg laying can only be completed by the queen, but where to lay eggs, what kind of eggs to lay, and how many eggs to lay, is determined by the worker bees. If the queen violates the rules, the worker bees will eat the eggs or larvae." Lanjie said, and couldn't help but walk to the blackboard. He asked Lei Tiangang: "Teacher Lei, can I draw pictures and explain?"

Lei Tiangang handed Lanjie a piece of chalk: "Draw it."

Ranger took the chalk and drew several regular hexagons on the blackboard. He was so active in Teacher Lei's theoretical class, not to please Teacher Lei, but to be interested in animal behavior from the bottom of his heart.

After drawing the picture, Ranger continued: "The royal family is very special. The mouth of its chamber is hanging downward at the bottom of the hive. The royal family usually has more than a dozen. When spring is in full bloom and food is sufficient, the queen will lay eggs in these dozen royal families. The larvae hatched from the royal family are fed royal jelly throughout the development stage. The larvae that feeds royal jelly develop into queen bee. Similarly, the queen is the queen, but the queen is the worker bee feeding royal jelly. The worker bee decides who to develop into the new queen. In other words, the mastermind behind the bee colony is the worker bee, and the queen is just a merciless egg laying tool. Haha, are you really that happy to be the king and queen?"

Yu Junjie inexplicably entered Ranger's rhythm. He said with emotion: "No, being a king and a queen is not happy, it can even be said to be sad."

"Yu Junjie raised a question, why did larvae that feed on royal jelly develop as queens from beginning to end? Is it just because royal jelly is nutritious and conducive to reproductive system development? In fact, I was also thinking about this question, and the documentary I watched only states the real phenomenon, but did not give a principle explanation. I later checked the information and found that there were many questions about bees that the scientific community has not yet made a clear explanation. Bees are common organisms, but many behaviors of this organism are fascinating! Oh, I'm off the hook, Teacher Lei, did you not delay your teaching?" Lanjie made a sorry gesture and returned to his seat.

"Students can think divergently, think deeply, and discuss heatedly. This is a good thing. I am happy to see this situation. Unlike the preliminary competition for the first time of the student competition, the National Finals is very Olympic and wins the National Finals. Students must reserve sufficient knowledge, but it is not simply rote memorization. The National Finals examines the students' knowledge and ability to flexibly apply knowledge. It is okay for you to fully exert your imagination in the national finals, and it can even be said to be necessary."

"Bees are both representative and unique social insects. There is indeed no clear statement in the scientific community about some mysterious behaviors of bees, but this does not hinder our bold and reasonable imagination. This type of question is often open-ended question types, without standard answers. You can deduce and explain based on the known scientific principles and form the logical self-consistent within the question, and you can get high scores. Now, I try to use the known theories of animal behavior and genetics to explain the various mysterious behaviors of bees..."

Lei Tiankang followed the competition outline and made appropriate and reasonable expansion.

The discipline of biology studies and unlocks unsolved cases between nature and humans themselves. Many biological phenomena have always existed, but they are difficult to explain thoroughly by human scientists.

If you can't solve the problem of routine operations, you have to use your creativity. Lanjie has been using his creativity all morning. He has listened to all the students' theory classes in the morning and interacted with his coach and teammates in a benign manner.

Add one!

Add one!

Add one!

Why don’t I add one creative thinking?

If you don’t add, don’t add it, go for a meal.

Ranger left the competition classroom, and when he went downstairs, he met someone: "Oh, Zhang Yutong, long time no see."

"Langjie, you are a busy person, it's really not easy to meet you."

"I'm busy with you, you're busy with your time. Everyone is from the third year of high school, and no one is busy. Save time and walk around the cafeteria?"

"Let's go."

Lanjie and Zhang Yutong came to Yangzhong Cafeteria together to get food and take a seat.

"Under normal circumstances, people who have been admitted to Shuimu University should not be that busy, but Langjie, you are not a normal person, so I want to know what are you busy with?" Zhang Yutong asked.

Ranjie said naturally: "What else can we be busy with? Of course, we science students are busy with mathematics, physics, chemistry and biology. What are you busy with? Where are you going to submit your application?"

"It's hard to say now, it depends on IELTS scores and college entrance examination scores."

"Isn't your international class just an IELTS class added to the college entrance examination class?"

"Yes, that's it. Like the serious college entrance examination classes, we go from 7 a.m. to 10 p.m.."

"Absolutely, I also have this schedule in the competition class."

The two former classmates and class members talked and highlighted the word "Friends".

Zhang Yutong suddenly took out two tickets, Sports Center, Evergrande vs. Perth Glory.

"Tonight, the semi-finals of the AFC Champions League." Zhang Yutong looked embarrassed that she wanted to go but couldn't.

Ranger asked: "You know that our senior high school students are busy with their studies and can't watch the football game, so what tickets do you buy?"

Zhang Yutong explained: "It was given to me by someone else."

"You know that even if someone else gave you a ticket, you can't go, so why should you accept it?"

"You slipped your hand and you stopped it. This is the situation. Langjie, what do you think of to deal with it?"

"Evergrande lost to Perth Glory 0-3 away. If Perth Glory scored at Evergrande's home court, it would be embarrassing. Evergrande is not the Evergrande in the past. If we see one game less, we will most likely not see Evergrande's final."

"Langjie, you have said so much, what is the specific plan?"

"If you go to the sports center, you have to skip classes. Skipping classes is a worrying thing."
Chapter completed!
