Ten days later, Bai Yulou and Simon and his party had adjusted to the gravity of Venus.

At the same time, they also found out the basic situation of residential, agricultural, industrial, mining and storage areas.

With their arrival, a large number of scientific research cabins, which had been attached to the agricultural area, were also redivided into separate scientific research areas.

Bai Yulou and others, who were officially working, came to a laboratory with a very high level of protection - the Venus Biological Laboratory.

This "Venus Biological Laboratory" studies the local creatures of Venus.

In the culture room in the laboratory, Bai Yulou saw the first Venus creature, nitrogen algae.

Nitrogen algae are only the size of fingers, translucent colloids, and have a large number of nitrogen air sacs in their bodies, which can float in the air with the buoyancy of nitrogen.

Nitrogen algae are named because these organisms have chlorophyll organisms similar to algae, which use photosynthesis to synthesize organic matter by absorbing carbon dioxide and a portion of free water molecules.

In the atmospheric ecosystem of Venus, a total of 37 species of nitrogen algae have been discovered, and they live in the atmosphere 30 km ~ 50 km from the earth's surface.

In addition to nitrogen algae, there are also air jellyfish that feed on nitrogen algae, and more than a dozen microorganisms parasitize the body of air jellyfish.

This is the ecosystem of Venus's atmosphere, a very resilient and very fragile ecosystem.

If it weren't for the arrival of Homo sapiens, they might not have been discovered by humans until decades later.

In fact, Homo sapiens has long been familiar with the existence of life on other planets.

The Moon has an underground biosphere, Mars also has an underground biosphere, and Venus has an atmospheric biosphere, which are very normal things.

We can't use the criteria of the Earth's biosphere to deny other planets, because life has infinite possibilities.

The earth and its creatures are actually a two-way street.

It is not the environment of the earth that creates living things, and in the whole process, living things continue to influence and adjust the earth.

For example, billions of years ago, cyanobacteria absorbed carbon dioxide and released oxygen, which directly killed most of the anaerobic bacteria and caused a large oxidation event on the earth.

The gradual increase in the proportion of oxygen in the atmosphere has also caused the earth to begin to cool down, and there is a significant alternation of hot and cold.

If the Earth had not given birth to cyanobacteria in time, then Venus could have been a lesson for the Earth.

Of course, the explosion of carbon dioxide concentrations on Venus does not mean that organisms cannot be born, for example, there is a layer of interlayer suitable for organisms in the high atmosphere of the atmosphere.

Nitrogen algae, air jellyfish, and the like were born in this environment.

In this Venus biological culture room, you can see nitrogen algae fluttering in the wind, they have been studied by many scientific researchers, and the synchronous robot is too convenient, and there is no need for people to come to Venus in person, and they can carry out research remotely.

Bai Yulou opened the biological tablet and inserted it into the laboratory's database, and then he found a lot of related research reports.

There are those who study nitrogen algae organelles, those who study reproduction, and those who study special compounds.

Among them, the study of how nitrogen algae resist radiation is the most popular among all research directions, because the magnetic field of Venus is weak and cannot stop the solar wind at all.

The habitat of nitrogen algae is located in the altitude zone of 30~50 kilometers in the atmosphere, although the concentration of the atmosphere in this area is several times higher than that of the earth's surface.

But there is no way to block ultraviolet rays and other high-energy rays, after all, there is no ozone layer in Venus's atmosphere.

Therefore, in the face of such strong ultraviolet rays, high-energy rays, and high-energy particles, many researchers are very curious about how nitrogen algae survive in this environment.

Bai Yulou was also very curious, and he carefully looked at the relevant research reports.

It turns out that the outer composition of nitrogen algae is very peculiar, and the inner core is also very peculiar.

The glial layer on its exterior is made up of dense sulfur compounds, which are made from sulfur dioxide in Venus's atmosphere, which effectively blocks harmful cosmic rays and energetic particles, while allowing only a portion of the available sunlight to enter the inner core.

Similarly, the inner core of nitrogen algae is encased in nitrogen, which is divided into a photosynthetic core and, most importantly, a reproductive core.

"Huh? This thing actually has extremely strong genetic 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, that is, nitrogen algae are sexual.

When they reproduce, it is also very simple, the neutral outer skin of the male nitrogen algae will gradually change to be positively charged, and the neutral outer skin of the male and female nitrogen algae will change to negative charge, and then attract each other to pair.

This is a universal skill for the Nitroalgae family.

Obviously, this is a way of reproduction according to local conditions, after all, this is not the earth, and the nitrogen algae do not have enough resources, and they cannot spray the offspring in the atmosphere casually, otherwise cosmic rays and high-energy particles will kill most of the progeny and cause serious genetic mutations.

But that's not the most amazing thing.

The most amazing thing about nitrogen algae is that their male and female germ cells are of the same type, and both male and female germ cells have 11 pairs of chromosomes intact.

When they enter a state of reproductive union, the male and female germ cells fuse together to form a diploid, which then completes the division and forms a new haploid, that is, the daughter body.

The progeny will build its own nitrogen algae between the male and female nitrogen algae, and the progeny will absorb the nutrients of the mother, but when the body size grows to about one-twentieth of the mother, it can break away from the mother and become a new nitrogen algae.

Under normal circumstances, the mother nitrogen algae can only reproduce 22~25 offspring, and then it will die completely.

And these nitrogen algae can develop into maturity, less than one-tenth.

Bai Yulou is more curious, is the nitrogen algae's response mechanism to the gene mutant individual, normally, the nitrogen algae's germ cells have a relatively strong self-repair ability, if the gene damage is too severe, the mother will automatically trigger the self-feeding mechanism, the part of the reproductive cells that have lost their reproductive value to digest.

This is the ability that human beings do not currently have, to be precise, the ability that human men do not have, the reproductive cells of human females have a certain ability to repair themselves, while the male germ cells have no way to repair themselves.

In order to solve the problem of genetic damage to male germ cells, Homo sapiens has also organized a number of research projects, including learning from the self-repair ability of female germ cells, but unfortunately there is no way to solve the huge difference between male and female germ cells.

However, the current reproduction mode of nitrogen algae has a certain reference significance for human beings.

Bai Yulou even found a blind spot.

That is "neutral", although the problem of men and women within the company is not serious, but the difference in the physiological structure of the two sides, there are still many hidden dangers.

If one day in the future, both men and women can reproduce offspring without any difference in physiological structure, then there is no difference between men and women.

After all, there are no obvious individual differences between nitrogen algae, and the reason why the germ cells of the two are male and female is mainly to facilitate pairing and reproduction.

Under certain conditions, the sexes of nitrogen algae can be converted into each other.
