Live broadcast: Ancient people accompany me to make up lessons

[Place corn planting at 25°C, darkness, and suitable moisture conditions for germination. Take the same number of germinated seeds regularly every day, dry half of them directly and weigh them, and cut the endosperm from the other half, dry and weigh them...]

This question is a fill-in-the-blank question, and everyone just watches the anchor write it slowly.

Regardless of what corn is, looking at the answer written by the anchor, it turns out that when the seeds grow up, they need watering to help the starch inside decompose into glucose, and then generate energy through respiration so that they can germinate.

You can’t quite understand the calculation questions below. You can only see the anchor calculating and writing the answers based on the line chart.

During the Kangxi period when winter was still deep, there was no other farm work after winter. A farm family gathered together to drink corn noodle porridge. Watching the anchor write a topic about corn, the youngest son Ji Xiang, who was already working in the fields, was puzzled: " If you can just plant corn and it will sprout, why do you have to go through so much trouble?"

Jixiang's father didn't quite understand either. He shook his head and remained silent.

The old man looked at the anchor who was still in the sky in the summer and narrowed his eyes: "This kind of land is also a science. We are used to it, so naturally we need to know how to plant it. They have never been to the ground at first glance, and they are studying it."

Research is also a word they learned when they followed the sky and watched the experts working on the loess.

Jixiang still doesn’t quite understand: “They have everything there, but they also want to grow corn to eat?”

The anchor's house is full of fresh fruits, vegetables and various kinds of meat. The beans are all finely chopped using a wall-breaking machine. There are no whole grains. Why do you need to study such boring stick noodles?

The elder sister Ruyi who had been listening to the silly brother couldn't stand it anymore and retorted: "They have so many different things to learn just in the agricultural college. Experts even have to study weeds and soil, and they must also study corn. Maybe they can't The corn cobs there can be turned into fine grains."

Ji Xiang didn’t believe it: “How can corn cobs be compared with white flour!”

Ruyi snorted: "Then if our family is lucky enough to win, we will ask the host what their corn cobs look like."

[The pulmonary stretch reflex is one of the reflexes that regulates breathing. Figure (a) is a schematic diagram of the pulmonary stretch reflex.

The receptors for this reflex are located in the lungs. After deep inhalation, the lungs expand, the receptors are excited, and the nerve impulses are transmitted to the brainstem through the afferent nerves, inhibiting inhalation and causing expiration...]

The doctors were very excited and thought this biology course was really good. Compared with chemistry, geography, and mathematics, it was much more approachable.

When we talked about viruses before, we all saw the perspective view of the human body. Later, when we talked about the dangers of alcohol, we also saw the animation of alcohol mixing in red blood cells and escaping, beating the cerebral cortex. We also saw how oxygen is converted into carbon dioxide through the lungs during breathing and then sent out. .

This nerve doesn't seem to be the meridians they usually talk about.

Looking at this picture and the answer written by the anchor, many academy students from time and space also gathered together to discuss with great interest.

"Brother Wu, if even holding our breath is controlled by the cerebral cortex, does that mean that whatever we do is controlled not by the heart but by the brain?"

Wu Chengen, who is already a celebrity in the academy, thought for a while: "This mind is not the other mind. What we have always said is from the heart, which is our own thinking. It is not really the heart that transmits blood in the body. Even if our behavior is controlled by the brain , what controls the brain is our other heart, our self-thinking."

He does not think that it is the human brain that controls everything, or that the person himself controls his brain.

Some people do not agree with his point of view: "Alcohol can paralyze the cerebral cortex and make people do many rude things after drinking. At that time, people are unconscious. In other words, it is the brain that controls people's behavior. Otherwise, why would you drink? People can’t control themselves?”

Some people supported his views, while others still maintained similar views to Wu Chengen. Students with different views began to seize the time to debate. The gentlemen looked at the students and stroked their beards. As long as there was no fight, everything was fine.

The debate about the heart and the brain in Longxi Academy has been staged in many times and places, and even the doctors quarreled over it.

[A pair of rats with normal coat color mated and gave birth to multiple rats. One of the male rats had abnormal coat color. Analysis believes that there are two reasons for the abnormal coat color of the rats: one is the direct result of genetic mutation (the manifestation and recessiveness of the gene that controls coat color The sex is unknown, the mutation only involves one gene in a pair of alleles on the autosomal chromosome of one parent); the second is the result of mating between recessive gene carriers...]

This question instantly reminded everyone of the previous lesson on hybrid rice, but unlike the reverence for food, even an old farmer who couldn't read a word could say a few sentences about the topic of rats.

"When cats and dogs give birth to litters, one or two of them will be completely different. This must be a genetic mutation."

"What kind of mutation? It's not like I don't know about your cat. Its previous mother was from Hua, and she followed her father when she gave birth to her. Now she has given birth to another one that looks like her mother. It's obviously a recessive gene. It's his mother's. The genes are not passed on to it, but to its children.”

"What is this, a cat's second-generation relative?"

"What nonsense are you talking about? This can be a second-generation marriage!"

"Then where did the white-haired and black cats come from? The cats here are all flowery. This must be some kind of mutation, right?"

Some people are also wondering whether this gene mutation will sometimes lead to any disease, just like what was mentioned before when we talked about consanguineous marriages.

After all, genes are a thing. Even if a cat gives birth to a normal litter, each litter may be different. Sometimes, some cats may be particularly weak, and they may be born with genetic diseases.

Thinking about this, many people felt a chill in their hearts and made up their minds. In the future, when kissing their children, they must not say anything close to them. Otherwise, what if something happens to their children in the future?

Liu Che, who will officially declare his retirement in a few days or two, is also thinking about it. At present, the most useful ones are geography, biology and chemistry. As long as these creatures are alive, they are all on the paper, from big to human. There are bacteria, both moving and immobile.

He thought of horses.

With my uncle and eldest father laying the foundation for recuperation, there are now many and good horses raised in Shanglin Garden, but compared with the horses of the Xiongnu, they are still a little behind.

When I woke up early in the morning, the young master had already told me that he had made stirrups based on last night's animation, waiting for him to take a look when he was free. Now it seems that in addition to tools, horses are also constantly optimizing their varieties, which is what they need. It will take longer.

Sure enough, we still have to take back the Loop, which is a good place with rich water and grass and suitable for raising horses.

He wondered boredly whether future generations would need particularly high scores in certain majors to apply for college. For example, if you score enough in biology, you could just study the different agriculture majors and the water conservation major.

The next step was to choose a question. They watched the anchor read both questions first, and then chose a chrysanthemum question.

They don't quite understand this question, but it feels to them as if they don't need soil for cultivation. It looks very magical. There are also those media with different concentrations of inorganic salts. Do you still need salt to grow chrysanthemums? What kind of salt is inorganic salt?

[After writing the question, Xiaoxiao stretched out his arms, picked up the water next to him and moistened his throat. When he saw that the time was exactly two minutes and seven-thirty, he started to pump the audience. 】

【1.Qin: Fan Zeng

2. Qin: Jia Quan

3. Han: Zhao Guo

4. Wei: Liu Sanshui

5. Han: Zhou Zi

6. Tang: Li Tai

7.Song: Lu Zhi

8. Ming Dynasty: Tang Yin

9. Ming Dynasty: Qin Sang

10. Qing Dynasty: Dong Ruyi]

Seeing the number of people on the list, some people were dissatisfied as to why there were always the most people from the Qin, Han and Ming Dynasties, while others were wondering why there were either no Qing people or only one.

Sun Quan: What’s going on? Even Cao Pi’s side is on the list. He’s the only one at the bottom of the Three Kingdoms list, right?

Seeing that someone from them was finally on the list, the people in Cao Wei were relieved.

If you really think about it, it's not like there is no one in Cao Wei, but Liu Xie, even if he is the son-in-law of the Cao family and Duke Shanyang, can he be considered a Wei person?

He put all the canopy hangings in Hanli.

The name Fan Zeng is very unfamiliar to the people of Daqin, but it is very familiar to the local wealthy people in Juhuan. Some people who know Fan Zeng are worried, thinking that he shouldn't ask Tianmu's anti-Qin issue so directly, right?

As for Lucky Audience No. 1, Fan Zeng himself, he really wanted to ask when Qin died or where the founder of Han was. However, Ying Zheng is still alive and he currently doesn’t really want to be the biggest conspicuous person in the Qin Dynasty and attract Ying Zheng’s attention. arrive.

The sixty-year-old man looked at the sky screen and felt that it was a pity not to ask anything. He simply saluted to the sky screen and asked the anchor what he thought of Qin and the Six Kingdoms.

As soon as this question was asked, the officials of Da Qin all knew that the proper survivors of the Six Kingdoms might still be the remnants of the Six Kingdoms. Needless to say, the emperor will definitely find him, so he needs to find someone himself first.

The descendants who are very familiar with this name are also curious, is it already the end of Qin at this time, but why didn't Duke Fan ask Xiang Yu about Qin?

Ying Zheng, who had no interest in biology and had been sitting in Xianyang Palace working, also looked at the sky. He also wanted to know what the anchor and future generations thought of his Da Qin.

[“What is my opinion? Let me start by saying that I don’t know the detailed history and system of Qin very well.

For Qin, the first unified feudal dynasty in history, it was progressive compared with the previous Warring States society. It unified the six countries and ended hundreds of years of war in the Central Plains. Books and cars share the same track. Many systems have made indelible contributions to our entire nation.

Although the Qin Empire was short-lived and the first feudal dynasty without a reference object fell apart after the death of Qin Shihuang, the Han Dynasty inherited the Qin system, and the feudal dynasty system for the next two thousand years was inherited from the Qin Dynasty. "

The history of Qin is too long away from their current situation. Even if Xiaoxiao now knows that he is talking to Qin people, Xiaoxiao doesn't have any special feelings, and he is even less familiar with the Six Kingdoms.

"In the case of the Six Kingdoms... in the society at that time, the establishment of a unified centralized dynasty was inevitable, but other countries did not have this opportunity and ability, so this historical mission was completed by Qin."]

With the Han dynasty having existed for hundreds of years, the subsequent dynasties basically recognized the anchor's statement that "the establishment of a unified centralized dynasty is inevitable". However, during the Qin Dynasty, people who still recognized the identity of the Six Kingdoms could not accept it. The anchor said this.

After all, the anchor's statement clearly stated that the existence of only one country is reasonable, and the other six countries are all useless people who are incapable of seizing the opportunity. Of course, the people of the six countries cannot accept it.

Zhang Liang, who had spent all his wealth and was running around, looked at the sky. He was surprised that Qin Neng still had a good reputation among anchors. However, as a Korean, he only recognized South Korea. Even he himself knew that Han had grown from aristocrat to Kings are basically rotten trash.

Liu Che: Although it is true that the Han Dynasty inherited the Qin system, we have also made improvements. Anchor, do you want to talk more about Qin Mo? If you don’t know, we will provide information here. Bao Qin is really not just talking nonsense.

Ten-year-old Sima Qian and his father Sima Tan were sitting at home, listening to the anchor's views on the Qin Dynasty. They were very curious about how the anchors and the others wrote their history books. It was completely different from their views on the Qin Dynasty.

He recognized Qin's system and said that the unification of the seven kingdoms was inevitable. There was no pity for Qin's demise. He said that the Han Dynasty inherited the Qin system. Although he himself was a Han, he didn't feel that he had any different attitude towards the Han... …What kind of history have you descendants studied?

No matter which country it is, as a county official who is a good helper to the county magistrate, Xiao He is wondering if these ten lucky viewers will be able to see the documentary promised to him by the anchor yesterday.

Lucky spectator No. 2, Jia Quan, is a sheepherder. He is driving his lambs to graze. Looking at the mark that he has been selected, his expressionless face is extremely happy.

He looked at the green grass now, and when he thought about it turning all yellow in winter, he wanted to ask the anchor if there was any way to make the sheep eat grass in winter.

["Let me check for you." Sheep are not raised in the south. In my hometown, chickens, ducks and geese are raised. The bigger ones are pigs. No one raises cows anymore. Xiaoxiao really doesn't know anything about sheep. Fortunately, the computer is open in front of me, so I can check the information at any time.

"Grass rack preservation, fermentation preservation, green storage preservation..."

She opened them one by one and showed them to everyone. 】

After looking at it, everyone found that the grass rack storage method is currently the most suitable for them. It is a large rack where the sheep grass needs to be placed in the early stage. The other methods are to bundle the grass neatly and neatly. It is not difficult, and they don’t raise many sheep. No need to save a lot.

For fermentation and preservation, the forage must first be piled into haystacks several people high and compacted layer by layer. The surface of the haystacks must be covered with soil or film. When the temperature of the haystacks reaches 60°C-70°C, it must be opened on sunny days. Stacks are dried, and finally the forage is dried. It's too troublesome, they have to measure the temperature accurately, and they don't have sheep to eat that much grass.

The storage of green storage is also very troublesome. It requires the use of a cellar, and the forage must be cut and packed in layers. It must be air-proof and water-proof, and must be inspected frequently.

Some businessmen are thinking that if the pasture can be laid out on a large scale, then sheep will no longer need to go out to graze every day. Wouldn't it be the same as the previous method of raising sheep on the canopy? It's rooty, so you don't need to worry about the sheep eating up all the grass.

Based on this calculation, as long as there is enough grass and no large area is needed, the number of sheep that can be raised can be much larger. Do you want to give it a try sometime...
