Chapter 979

It's time for a break. Everyone is warming up in the tent. Just as Feng LAN comes to punch in the movie room, Qin Zhuo starts to chat with Xiao Feng.

It's only a week since I left Changbai mountain last time, but it's much colder here than before, especially in the deep mountains and old forests. As long as I stay still, I can go there.

Qin Zhuo said: "I really admire the bears. How can they sleep for a few months without freezing?"

"You're wrong. Bears don't hibernate for several months. In fact, they are half asleep at most. During hibernation, they are still sensitive. They wake up when they have a sound and occasionally go out of the cave to look for food."

"Ah? What's the principle of not eating or drinking in recent months? "

"Well, the bear doesn't eat or drink because it already eats and drinks in autumn. When winter comes, there is a shortage of food. In order to avoid excessive consumption, they have to stay still. In this way, they can lower their body temperature, slow down their heart rate, slow down their metabolism, and naturally survive without much energy consumption. "

After a long time, Xiaofeng teacher's online class appeared again. Because of the live broadcast, fans were excited to participate in real time.

Fan: ah, I usually watch video. I first met the live version of Xiaofeng's online class.

Fan: Life series, I can finally participate in the classroom.

Fan: I wanted to have a lesson from teacher Xiaofeng when I majored in wildlife research in huaida University. I didn't expect to miss it in the University, but it was realized in the program. It's my destiny to go around!

Fan: Miss Xiaofeng, please continue your popular science.

Fan: only I found that teacher Xiaofeng has meat?

Fans: Mr. Xiaofeng, you're all fleshy at home. Please go out of the gate quickly and go for a walk in the wild with Zhang Anzhi.

Fans have a sense of existence in all kinds of brushes, but they don't associate Mr. Xiaofeng's long meat with others at all.

Ho, later netizens who knew the truth said that they were too naive at that time!

But it's too late to read the comments. The comment area is rolling dozens of items in a second, and each item is pushed up by the latter at the beginning, which is hard to understand!

It's so hard.

After several unsuccessful struggles, she finally gave up the barrage and continued the unfinished science popularization.

"In winter, the bear only moves in the cave, but it doesn't mean that it completely loses its perception of its surroundings. If you want to see it sleep and then run to take pictures with others, like a TV play, the bear will turn you into a dish every minute."

"So when you travel in the wild, you should not be curious when you see these large animals, whether they are in a daze or sleeping. It is safest to avoid them immediately."

They all looked like they had learned a lot. Fenglan thought of something and said, "by the way, the hibernating black bear is only from the north. The southern black bear doesn't hibernate. You can understand this little cold knowledge."

"Ha? Why? " Once again, Qin Zhuo was full of questions.

"Hibernation is just a way for bears to survive the winter. In order to survive the cold winter, they have to survive. But in the south, there is no shortage of food and no severe cold, so bears do not need to adjust themselves."

"It seems that it's better to be a southern bear."

Qin Zhuo's childish view has once again aroused fans' admiration.
