Just as the mind and conscience arouse interest, life itself does not escape the curiosity of the human being who wants to know everything. It is normal that Biology is an interesting science because it seeks answers related to the way life itself works.
If you are interested in testing your knowledge about this science, keep reading; Here you will find a selection of questions about Biology (with their answers).
In the following article you will find a selection of Biology questions (with their answers) that any student or interested in this science should know how to answer without problems. With that said, I begin.
The cell is the fundamental unit of life Whether we are talking about a being made up of a cell (unicellular) or a set of them (multicellular), this element is always present. Thanks to their differentiation in functions, evolution has given way to increasingly complex organisms.
2. Who was Robert Hooke?
Hooke was an English scientist who coined the word cell after seeing them for the first time. This researcher observed a sheet of cork with a microscope, seeing a network of voids (hence the name cell), although he did not know how to associate this with the real functions of these small microscopic bodies.
3. What is the difference between prokaryotic and eukaryotic cells?
The main differences between the two major types of cells are the fact that prokaryotes (e.g. bacteria) do not have any organelles (complexes that perform functions) inside and its genetic material is free inside the free membrane and not in a nucleus as in the case of eukaryotes.
4. What is the longest-lived species of vertebrate animal in the world?
It is the Greenland shark, or boreal shark (Somniosus microcephalus), which is estimated to live up to approximately 400 years.
5. And the difference between plant and animal cells?
The answer to this question about Biology is easy, the big differences are that only plant cells have a cell wall, which generates the rigidity that characterizes plants, and they have organelles known as chloroplasts, which are responsible for photosynthesis.
6. What is genetic material?
A fairly important Biology question. If before I talked about the cell being the unit of life, the genetic material is the basis for this. It stores the information for the creation of the cell, as well as all its functions.
This Biology question is related to the previous researcher, since the theory of biogenesis indicates that a previous life is necessary to generate life. That is, life is not generated from nothing.
8. What does “sterilized” mean?
Saying that an environment is sterilized means that in principle all life, even at the level of microorganisms, has been eliminated from that environment.
9. Who was Charles Darwin?
Darwin was an English naturalist, who, along with Russel Wallace, promoted the idea of biological evolutionary theory through natural selection a mechanism that ensures that whoever survives has a better chance of reproducing.
10. What is Biological evolutionary theory?
Related to Darwin is the evolutionary theory, which indicates that current living beings are the result of progressive changes in the reproductive successes and failures of ancestors These ideas eliminated God’s hand in explaining the creation of species.
11. What are duplication, transcription and translation all about?
As a general rule, the cell stores its information in the form of DNA. Duplication occurs when an identical copy of DNA is made for cell division. Transcription is the passage of DNA into a chain of messenger RNA and translation is the passage of the latter to a protein.
12. What is a protein?
A protein is a chain of amino acids (AA), which the cell uses as a tool to perform its functions.
13. What is the difference between DNA and RNA?
I will answer this question very briefly. Without going into many details, the differences are found at a structural and functional level.
14. Who was Gregor Mendel?
Mendel was a monk and naturalist who is considered the father of genetics for his famous studies with peas, revealing many of the mysteries of genetic inheritance.
15. What is a gene?
DNA is made up of a chain of nucleic acids (NA). The gene is a fragment of this, and contains the information to create a specific protein mostly.
16. What is the genetic code?
The genetic material has its own language. Simply put, the order of the ANs that make up DNA offers information, whether it is a gene or an initiation sequence, for example.
17. What is the cell cycle in eukaryotes?
Eukaryotic cells follow a life cycle, and their purpose is cell division. This presents four phases, differentiated into two large groups: the interphase, where the cell prepares for its division; and the M phase, where partitioning into more than one cell takes place.
18. What are the differences between mitosis and meiosis?
There are two types of cell division, which differ mainly in their outcome. While in mitosis two identical cells are formed, in meiosis it ends with four cells and each one has a single strand of DNA, instead of two.
19. What is a mutation?
This Biology question refers to one of the errors that can occur in DNA. Mutation is nothing other than a change in the sequence of a gene changing the meaning of this information.
20. What is apoptosis?
Just as we talk about proliferation, cells also have programmed cell death. This process is known as apoptosis.
21. What is the only species of canid whose diet is composed almost exclusively of termites?
It is the bat-eared fox, also called ototion, a relatively common animal in various parts of sub-Saharan Africa.
22. What is an ecosystem?
All living beings, such as animals and plants, have a relationship both with each other and with the environment that surrounds them. The whole of this is what we know as an ecosystem.

23. What differentiates gymnosperms from angiosperms?
The answer to this question related to plants is the following: gymnosperms do not have showy flowers, unlike angiosperms.
24. What differentiates invertebrates from vertebrates?
Another general classification, in this case referring to the animal kingdom, is the division between vertebrates and invertebrates. The former have a bone structure, and the latter do not.
25. What types of reproduction exist?
Generally speaking, there are two types of reproduction: asexual and sexual. The difference is that the second makes use of gametes (e.g. sperm).
26. What is the name of the process by which two groups of living beings without close relationships evolve independently and develop similar structures to each other, despite starting from slightly similar ancentral structures?
This is evolutionary convergence, or convergent evolution, which is reflected in, for example, the independent evolution of wings in birds and mammals (bats).
27. What is the northernmost place where we find a stable population of penguins?
In the Galapagos Islands, where the Galapagos penguin lives (Spheniscus mendiculus).
28. What is the name of the species of non-extinct aquatic mammal that is known, among other things, for laying eggs?
It is the platypus, which along with the echidnas, is part of the order of monotremes, the only mammals currently existing that have young by laying eggs.
29. What name is given to the synapsid animal that lived during part of the Permian and was characterized by having an enormous dorsal sail formed from the structure of its vertebrae?
It was the dimetrodon, one of the great predators of its time.
30. What is metabolism?
Metabolism refers to all chemical or physicochemical reactions carried out by cells or organisms.
31. What is the species of the order of carnivores that is the smallest of all, whose adult specimens measure only between 12 and 20 centimeters in length?
It is the common weasel (Mustela nivalis), whose flexibility and small size allows it to get into the galleries dug by all types of rodents to hunt them
32. What species of tree is considered a living fossil, having representatives of its genus very similar to this one in the Jurassic period?
He Gingko biloba It is part of a lineage of trees so old that its evolutionary branch has no close relatives.
33. Who was Louis Pasteur?
Louis Pasteur is considered the “father of modern microbiology”, since thanks to his work refuted the idea of spontaneous generation, proving that life does not appear by chance. He is also known for his sterilization technique: pasteurization.
