Man has always had a profound need to understand and master the knowledge of the functioning of all living beings. This has allowed him to expand the frontiers of knowledge, but above all else, to exercise dominion over a part of nature. L to biology as a science that studies living things, has served to understand the evolution of all species and to control its development work. The transcendental role of biology is given by the possibility of knowing and protecting all those living organisms that allow man to perpetuate his own species.
The Biology section , which readers will be able to navigate with ease, contains definitions, concepts and development of all the topics inherent in the study of all living beings . Animals, plants, single-celled organisms, all accompanied by excellent images so that the experience of introducing ourselves to the world of biology is exciting. Each topic is treated with rigor and simplicity, so that it can be used as a way to expand knowledge or as a complement to school tasks.
The tropical forest is considered the ecosystem that has the greatest amount of life on earth. Its trees, thickly populated, are the perfect habitat for thousands of species and its soils are a natural mantle that causes the proper development of plants and animals. What is the tropical forest? The tropical forest is the type of forest that experiences high rainfall due to its location, its humidity is … Read more
The trophic chain, also known as the food chain , in ecology, is the sequence of transfers of matter and energy in the form of food from one organism to another. Food or trophic chains become intertwined in a food web because most organisms consume more than one type of animal or plant. Plants, which convert solar energy into food through photosynthesis, are the main source of food … Read more
The primary consumers are often herbivores that feed on plants autotrophic, which produce their own food through photosynthesis . Many primary consumers adopt different feeding strategies to maximize the effectiveness of foraging behavior. They generally have specific physiological adaptations that allow them to process carbohydrates produced by photosynthesis. Many of them also have symbiotic bacteria , which live inside a special organ called the cecum and help with the digestion of plant material. What are primary consumers? They … Read more
A trophic level is the group of organisms that exist within an ecosystem that occupy the same level in a food chain . There are five main trophic levels within a food chain, each of which differs in its nutritional relationship to the primary energy source . The primary energy source in any ecosystem is the Sun , although there may be some exceptions in ecosystems that inhabit deep waters . What are trophic levels? They … Read more
The human body does thousands of things at once, from sending electrical impulses , pumping blood , digesting food , making proteins , and much more. All these activities can be done thanks to cells, those tiny units of life that are like factories , full of machinery designed to carry out the business of life. Cells make up all living things , and they can come in different shapes and sizes . Despite … Read more
An allele is an alternate form of a gene that is found in a specific position on a specific chromosome . These DNA encodings determine the different traits that can be transmitted from parent to child through sexual reproduction . The process by which alleles are transmitted was discovered by Gregor Mendel and was formulated in what is known as Mendel’s law of segregation.. In people, traits such as eye color can be caused by the interaction … Read more
The genotype is basically the genetic constitution that an organism possesses. The genotype is responsible for determining the potentials and hereditary limitations that an individual possesses from embryonic formation until they reach adulthood . Among organisms that reproduce sexually, an individual’s genotype comprises the complex set of genes that are inherited from both parents. It can be shown mathematically that sexual reproduction practically guarantees that each individual will have a unique genotype with the exception of … Read more
In genetics , dominance belongs to the property that a gene (or allele ) has in relation to other genes or alleles. A gene or allele shows dominance when it suppresses the expression, or dominates the effects, of the recessive gene or allele . There are different forms of dominance such as complete dominance, incomplete dominance and codominance . Codominance is a form of dominance in which the alleles of a pair of genes in … Read more
The word genotype refers to the genetic makeup of an organism; in other words, it describes the complete set of genes in an organism. In a more restricted sense, the term can be used to refer to the alleles , or variant forms of a gene, that are carried by an organism. Humans are diploid organisms , which means they have two alleles at each genetic position or locus, … Read more
A unicellular organism is an organism that is made up of a single cell . This means that all life processes occur in them, such as reproduction, food, digestion and excretion, but all of them occur in a single cell. The amoebae , the bacteria and plankton are just a few types of unicellular organisms . They are generally microscopic and cannot be seen with the naked eye and are known … Read more
