What do you think this animal is called? It's a Tasmanian devil.

(Allow me a brief digression. I'm the last of Generation Z (born in 2010). The Bugs Bunny Show is a cartoon from way back when, and I haven't seen it, but thanks to the character on the clothes, I have a rough idea of ​​what the characters look like.)

Tasmanian devils are funny guys from New Zealand. They're the only animals known to have transmissible cancer, meaning they transmit it through the bite of a fellow devil. This is due to their very small population, so their transmissible cancer can be considered akin to the Habsburger Unterlippe.

Kleptoplasty is the accumulation of algal chloroplasts in the tissues of an organism that feeds on them.

The organism digests the algae, except for the chloroplasts, but the chloroplasts continue to photosynthesize for some time, and the products of photosynthesis are used by the host.

Pictured: Elysia, a marine photosynthetic mollusk.

And it happens!

Some content from Russian Olimpiad of biology:

1) The first photo shows pneumophores, or breathing roots. They are present in bald cypress and, as the name suggests, are used for respiration in water-dwelling trees.

2) Strangler figs, or strangler figs, are a common name for several species of tropical and subtropical plants that share a specific strangling lifestyle. On this photo host tree was killed.

One of turbellarian larvas: Muller’s lavra

[albus-corvus-linnaeus]

This is a small Selaginella. This particular specimen is a couple of centimeters in size. It is a relative of the club mosses, and exhibits anisophily and iridescence. Anisophily refers to the difference in leaf size: small ventral leaves and large dorsal leaves. Iridescence is a special coloration that creates an iridescent effect (a visible bluish-gray sheen). What an interesting plant.

This is a modal object of genetics, embryology, molecular biology and etc. It’s a nematode, who has a fixed count of cells. This is called eutelia. Worm has around 1000 cells and 302 of this is neurons. Other worms and animals don’t have eutelia and because of this the nematode is unique

I’m posting some photos of animals and flowers from biological practice at the Zvenigorod biological station of Moscow State University. We saw many species, as well as traces of other species' activity in just a week!!! This is a fantastic experience

Memes aside, explanation is that insects are technically crustaceans by virtue of being part of a clade called Pancrustacea.

Already insects and crustaceans were considered to be more closely related to each other than to Chelicerates like arachnids and horseshoe crabs due to morphological similarities. However genetic testing confirmed the relationship.

Here's a phylogenetic tree of arthropods:

You can see the alpha male ruff (Calidris pugnax). Ruffs have three types of morphs: females, effeminate males and alpha males. The latter actively court females and express a high degree of aggression towards other males. While alpha individuals dance, attracting females, effeminate males fly there, who offer to quietly mate with the female. But since these males are very few in the population, females remain for handsome comrades. This is how both male morphs are transferred.

The sunfish with the Scuba Diver for scale and its tiny babies.

The school curriculum tells us about this fish as the most prolific. It spawns up to 300 million eggs at a time!

And here is what they told us about it at the Summer School of the Biology Department of Moscow State University:

For a long time it was believed that this colossus, despite its size, is not able to resist the force of currents, which immediately places it in the category of Plankton. Yes, yes, along with microalgae, tiny crustaceans and jellyfish!

However, not everything is so clear!

Further observations showed that in shallow water the sunfish is able to purposefully swim at a speed of just over 3 km/h. But in the open sea it completely trusts fate...

it’s funny, because in Russian language this fish is called “fish-moob”

Today I faced the problem that my grandmother does not know how mold reproduces. I will explain so that you do not face such a problem.

What is the situation? Today, we had dinner with the family and grandma decided to get out her homemade pickles, but they were spoiled. White mold appeared on them. And grandma left them open on the table.

YOU SHOULD NOT DO THIS. The main way mold reproduces is by forming spores. They are very small and fly in the air, but if adult mold is left open, the concentration of pores in the air will increase and the likelihood of spoilage of other products will increase.

Please do not leave food like this, throw it away immediately.

The bird didn't die, the bird is resting.

In fact, it flew into a closed house, we looked for the owners, caught it and released it.

At the same time, we demonstrate an effect known to ornithologists who ring small birds.

By the way, does anyone know an explanation for this phenomenon?

Have you ever wondered: “Why is kefir so much more sour than yogurt?”

This difference in taste is due to the difference in the bacteria that produce the fermentation. The bacteria in yogurt produce lactic acid from sugar, while the bacteria in kefir produce lactic acid, ethyl alcohol, and vinegar from sugar. Thus, kefir is much more sour than yogurt.

And it turns out that kefir contains alcohol.

Chromatography is a method of separating substances, most often pigments, due to their polarity. All substances are divided into polar and non-polar, polar substances dissolve better in non-polar solvents and vice versa. Accordingly, substances of the same name with a solvent are transferred along the plate (paper) further than substances of different names.

In this example we see the chromatography of a concentrated solution of pigment obtained from a mint leaf. We can see that there are only 5 spots. Listed from bottom to top:

1) Neoxanthin - yellow addition pigment, protects chlorophyll from overload

2) Chlorophylle B - addition chlorophyll for all photosynthetic organisms

3) Chlorophylle A - basic chlorophyll for all photosynthetic organisms

4) A mixture of undissolved chlorophylls - error of the method

5) β-Carotene - orange addition pigment, protects chlorophyll from overload. A lot of in a carrot.

Dictamnus albus is a plant popularly known as the Burning Bush. It was not given this name by chance. The fact is that it secretes specific bactericidal flammable substances, most often in warm, windless weather. This is how fires can occur, in which the plant itself does not burn.
