33 Biology questions (and their answers)

If you are interested in this branch of science or if you study it, you should be able to answer them.

Just as the mind and consciousness arouse interest, life itself does not escape the curiosity of human beings who want to know everything. It is only natural that biology is an interesting sciencebecause it seeks answers related to the very functioning of life.

If you are interested in testing your knowledge about this science, read on; here you will find a selection of questions about biology (with answers).

33 Biology questions to test your knowledge

In the following article you will find a selection of Biology questions (with their answers) that any student or person interested in this science should be able to answer without problems. That said, I begin.

1. What is the cell?

The cell is the fundamental unit of life. Whether we are talking about a being formed by a single cell (unicellular) or by a group of cells (multicellular), this element is always present. Thanks to its 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 cells 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 prokaryotic cells (e.g. bacteria) have no organelles (complexes that perform functions) and their genetic material is free inside the free membrane. their genetic material is free inside the free membrane, and not in a nucleus as in the case of eukaryotes.and not in a nucleus as in the case of eukaryotes.

4. What is the longest-living vertebrate animal species in the world?

It is the Greenland shark, or boreal shark (Somniosus microcephalus), which is estimated to live up to 400 years.

What is the difference between plant and animal cells?

The answer to this question on Biology is easy, the big differences are that only plant cells have a cell wall, which generates the rigidity that characterizes plants, and have organelles known as chloroplasts, which are responsible for photosynthesis.

6. What is genetic material?

A very important biology question. If I spoke earlier about the cell being the unit of life, the genetic material is the basis for this. In it is stored the information for the creation of the cell, as well as all its functions.

7. What does the theory of biogenesis say?

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?

To say that an environment is sterilized means that in principle all forms of life, even at the level of microorganisms, have been eliminated from that environment.

9. Who was Charles Darwin?

Darwin was an English naturalist, who, together with Russel Wallace, promoted the idea of Biological evolutionary theory through natural selection.The mechanism that tries that the one who survives has more possibilities to reproduce.

10. What is the Biological evolutionary theory?

Related to Darwin is the evolutionary theory, which indicates that the present living beings are the result of progressive changes in the successes and the result of progressive changes in the reproductive successes and failures of the ancestors.. These ideas eliminated the hand of God in the explanation of the creation of species.

11. What are duplication, transcription and translation 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 messenger RNA strand, and translation is the passage of DNA into a messenger RNA strand.and translation is the passage of the latter into a protein.

12. What is a protein?

A protein is a chain of amino acids (AA), which the cell uses as a tool to carry out its functions.

13. What is the difference between DNA and RNA?

I will answer this question in a very summarized way. Without going into too much detail, the differences are at the structural and functional level.

14. Who was Gregor Mendel?

Mendel was a monk and naturalist who is considered to be the father of genetics for his famous studies with peas, unraveling many of the mysteries of genetic inheritance.

15. What is a gene?

DNA is formed by a chain of nucleic acids (NA). The gene is a fragment of this, and contains the information to create a particular protein. contains the information to create a specific proteinmainly.

16. What is the genetic code?

The genetic material has its own language. Simply put, the order of the NAs that make up DNA provides 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 its purpose is cell division. This has four phases, differentiated into two large groups: the interphase, where the cell is prepared for division; and the M phase, where the division 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 concludes with four cells and each one has a single DNA strand, instead of two.

19. What is a mutation?

This biology question refers to one of the errors that can occur in DNA. A mutation is nothing more than a change in the sequence of a geneThe mutation is nothing more 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 a 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 eared fox, also called the otocion, an animal relatively common in various parts of sub-Saharan Africa.

22. What is an ecosystem?

All living things, such as animals and plants, have a relationship both with each other and with the environment around them. The whole of this is what we know as an ecosystem.

23. What differentiates gymnosperms from angiosperms?

The answer to this plant-related question 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 kingdomis the division between vertebrates and invertebrates. The first ones present a bony structure, and the second ones, not.

25. What types of reproduction are there?

Generically, there are two types of reproduction: asexual and sexual. The difference is that the second one makes use of gametes (e.g., spermatozoa).

26. What is the process by which two groups of living beings without close kinship evolve independently and develop structures similar to each other, in spite of starting from ancestral structures that are not very similar?

This is evolutionary convergence, or convergent evolution, which is reflected in, for example, the independent evolution of wings in birds and mammals (bats).

27. Where is the northernmost place where we find a stable population of penguins?

In the Galapagos Islands, home to the Galapagos penguin (Spheniscus mendiculus).

28. What is the name of the non-extinct aquatic mammal species that is known, among other things, for laying eggs?

It is the platypus, which together with the echidnas, forms part of the order of monotremes, the only mammals existing today that have young 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 the chemical or physico-chemical reactions carried out by cells or organisms.

31. Which species of the carnivore order is the smallest of all, with adult specimens measuring only 12 to 20 centimeters long?

It is the common weasel (Mustela nivalis), whose flexibility and small size allows it to get into the galleries dug by all kinds 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?

The Gingko biloba is part of a lineage of trees so ancient that its evolutionary branch has no close relatives.

33. Who was Louis Pasteur?

Louis Pasteur is considered the "father of modern microbiology", because thanks to his work he refuted the idea of disproved the idea of spontaneous generationby demonstrating that life does not appear by chance. He is also known for his sterilization technique: pasteurization.
