Ten days later, Bai Yulou, Simon and his party had adapted to the gravity of Venus.
At the same time, they also found out the basic situation of residential areas, agricultural areas, industrial areas, mining areas and storage areas.
With their arrival, a large number of scientific research cabins that had been attached to the agricultural area were redivided and established as separate scientific research areas.
Bai Yulou and others, who were officially working, came to a laboratory with a very high level of protection-Venus Biological Laboratory.
This "Venus Biological Laboratory" studies the local organisms of Venus.
In the culture room in the laboratory, Bai Yulou saw the first Venusian organism - nitrogen algae.
Nitrogen algae are only the size of a finger, a translucent colloid body, and have a large number of nitrogen gas sacs in their bodies, which can float in the sky with the help of the buoyancy of nitrogen.
They are named nitrogen algae because these organisms have chlorophyll organisms similar to algae. They absorb carbon dioxide and some free water molecules and use photosynthesis to synthesize organic matter.
In the atmospheric ecosystem of Venus, a total of 37 species of nitrogen algae have been discovered so far, and they live in the atmosphere 30 kilometers to 50 kilometers from the surface.
In addition to nitrogen algae, there are also air jellyfish that feed on nitrogen algae, and more than a dozen kinds of microorganisms that live in the air jellyfish.
This is the ecosystem of Venus' atmosphere, a very tenacious yet very fragile ecosystem.
If it hadn't been for the arrival of the Homo sapiens company, it might have been decades before they were discovered by humans.
In fact, the Homo sapiens company has long been accustomed to the existence of life on other planets.
The moon has an underground ecosystem, Mars also has an underground ecosystem, and Venus has an atmospheric ecosystem. These are all very normal things.
We cannot deny other planets based on the standards of the earth's ecosphere, because life has unlimited possibilities.
The earth and earth creatures are actually the result of a two-way journey.
It is not the earth's environment that creates living things. During the entire process, living creatures continue to influence and adjust the earth.
For example, cyanobacteria billions of years ago, their family absorbed carbon dioxide and released oxygen, directly killing most of the anaerobic bacteria and causing a great oxidation event on the earth. Today, the iron oxide and copper oxide on the earth
Such minerals are the result of the Great Oxidation Event.
The gradual increase in the proportion of oxygen in the atmosphere has also caused the earth to begin to cool down, with an obvious alternation of hot and cold.
If the earth did not give birth to cyanobacteria in time, Venus may be a lesson to the earth.
Of course, the explosive carbon dioxide concentration on Venus does not mean that organisms cannot be born. For example, high in the atmosphere, there is an interlayer that is more suitable for organisms.
Nitrogen algae, air jellyfish and the like were born in this environment.
In this Venusian biological culture room, you can see nitrogen algae blowing in the wind. They have been studied by many scientific researchers. Synchronized robots are so convenient. People do not need to come to Venus in person and can conduct research remotely.
Bai Yulou opened the biological tablet and inserted it into the laboratory's database, and then he found many related research reports.
Some study nitrogen algae organelles, some study reproduction, and some study special compounds.
Among them, the study of how nitrogen algae resist radiation is the most popular of all research directions, because the magnetic field of Venus is so weak that it cannot block the solar wind at all.
The habitat of nitrogen algae is located at an altitude of 30 to 50 kilometers in the atmosphere, although the atmospheric concentration in this area is several times higher than that on the earth's surface.
But this cannot block ultraviolet rays and other high-energy rays. After all, there is no ozone layer in the atmosphere of Venus.
Therefore, faced with such strong ultraviolet rays, high-energy rays, and high-energy particles, many scientific researchers are very curious about how nitrogen algae survive in this environment.
Bai Yulou was also very curious. He carefully looked through the relevant research reports.
It turns out that the surface composition of nitrogen algae is very strange, and the core is also very strange.
The colloid layer on its outer surface is composed of dense sulfur compounds, which are made from sulfur dioxide in the atmosphere of Venus. It can effectively block harmful cosmic rays and high-energy particles, while only allowing a part of the available sunlight to enter the core.
Similarly, the core of nitrogen algae is wrapped in nitrogen, and the core is divided into a photosynthetic core and the most important reproductive core.
"Huh? This thing actually has extremely strong gene repair capabilities?" Bai Yulou saw a very interesting research report.
The reproductive core of nitrogen algae can be divided into male and female according to different types. In other words, nitrogen algae are gendered.
When they reproduce, it is also very simple. The neutral coat of the male nitrogen algae will gradually change to positively charged, while the neutral coat of the male and female nitrogen algae will change to negatively charged, and then they will attract each other and mate.
This is a common skill of the nitrogen algae family.
Obviously this is a reproduction method adapted to local conditions. After all, this is not the earth. Nitrogen algae do not have enough resources, and they cannot spray their offspring into the atmosphere casually. Otherwise, cosmic rays and high-energy particles will kill most of the offspring and cause
Severe genetic mutations.
But that's not the most amazing thing.
The most amazing thing about nitrogen algae is that their male and female reproductive cells are of the same type. Both male and female reproductive cells have 11 intact pairs of chromosomes.
When they enter the state of reproductive union, the male and female germ cells will fuse together to form a diploid, and then complete the division to form a new haploid, that is, the birth of daughter bodies.
The daughter body will build its own nitrogen algae body between the male and female nitrogen algae, and the daughter body will absorb the nutrients of the mother body, but when the size grows to about one-twentieth of the mother body, it can separate from the mother body and become a brand new nitrogen algae.
Under normal circumstances, the mother nitrogen algae can only reproduce 22 to 25 offspring, and then they will die completely.
However, less than one tenth of these nitrogen algae sporophytes can mature.
What Bai Yulou is more curious about is the response mechanism of nitrogen algae to genetically mutated individuals. Under normal circumstances, the germ cells of nitrogen algae have relatively strong self-repair capabilities. If the genetic damage is too serious, the mother will automatically trigger the self-eating mechanism and will
The part of the reproductive cells that have lost their reproductive value is digested.
This is an ability that humans currently do not have. To be precise, it is an ability that human males do not have. Human female reproductive cells have a certain ability to repair themselves, but male reproductive cells have no way to repair themselves.
In the past, in order to solve the problem of genetic damage to male germ cells, the Homo sapiens company has also organized a number of research projects, including drawing on the self-repair ability of female germ cells. Unfortunately, the huge difference between male and female germ cells has meant that there has been no solution.
However, the current reproduction model of nitrogen algae has certain reference significance for humans.
Bai Yulou even discovered a blind spot.
That is "neutralization". Although the problem between men and women within the Homo sapiens company is not serious, the differences in the physiological structures of both parties still pose considerable hidden dangers.
If one day in the future, there is no physical difference between men and women and they can both reproduce, then there will be no difference between men and women.
After all, there are no obvious individual differences between nitrogen algae. The reason why the reproductive cells of the two species are divided into male and female is mainly to facilitate pairing and reproduction.
Under certain conditions, the sexes of nitrogenous algae can be converted into each other.
