Autotrophs and Heterotrophs: Who’s Who in the World of Living Nature?
The world of living nature is incredibly diverse, but all organisms can be broadly divided into two major groups based on how they get their food: autotrophs and heterotrophs. Understanding this classification is key to comprehending how ecosystems function and how energy moves from one organism to another.
Why Do Objects Expand When Heated? The Science of Thermal Expansion Explained
Every object, whether solid, liquid, or gas, is made up of tiny particles: atoms and molecules. These particles are in constant motion, even if that movement isn’t visible to the naked eye. When we heat an object, we give its particles additional energy.
Ethology: The Science of Animal Behavior
From the moment humans appeared on Earth, we had to constantly and carefully observe the behavior of the animals around us, and know their habits well. In fables and myths, the images of animal-people and animal-gods fantastically intertwined with a basic understanding of the actual behavior of certain animals, alongside specific human qualities. In this case, it is especially important to note that not only the “animal-like” creations of human imagination but also real, existing animals were endowed with human qualities. Their behavior was viewed through the lens of human motives and actions. This “humanizing” of animals, or anthropomorphism, as we call it today, played a significant role in the philosophical concepts of ancient thinkers who believed in the possibility of the soul migrating back and forth between humans and animals.
Cosmic Strings: The Mysterious ‘Seeds’ of the Universe
Extremely heavy and thin as hair, these astonishing strands of matter are known as cosmic strings. Scientists believe that in the history of the Universe, they played the role of “seeds” from which galaxies and their giant filamentary clusters grew. Who scattered these “seeds”? Have they survived to the present day, and is it worth looking for them in space? And, more generally, how much can we trust cosmological models? Are scientists mistaken in predicting such “oddities” in the cosmos?
Paramecium Caudatum – the Most Complex of the Simplest
Life on our planet is characterized by an incredible variety of all kinds of living organisms, sometimes having an incredibly complex structure. All this diversity of life: from the simplest insects and plants to us, people (the most «complex organisms») consist of cells, these small bricks of living matter. If a human is the crown of biological evolution, then it will be very interesting to investigate its beginning: the simplest unicellular organisms which at the dawn of history became the founders of all life. The paramecium caudatum (along with amoeba) is one of the most famous simple unicellular creatures. What are the characteristics of the paramecium? What do paramecia eat? How do paramecia reproduce? Read on about all this below.

Chromosomes
Chromosomes are nucleoprotein structures of a eukaryotic cell. Most of the genetic information is stored in chromosomes. Due to its ability to reproduce itself, it is the chromosomes that provide the genetic link between generations. Chromosomes are formed from a long DNA molecule, which contains a linear group of many genes, and all genetic information, whether it be about a human, an animal, a plant, or any other living creature.
