The foreign animals of Peru are species originating from other countries that man has introduced to that nation. The impact on the local, regional or national ecology of these new species is variable. Some species could contribute, among other things, to pest control, being considered highly beneficial as they represent a natural alternative to chemical
The fauna of Puno is part of the biodiversity found in Peru. Due to its unique geographic characteristics, there are a large number of native species in the region. It should be noted that within the department of Puno is Lake Titicaca, an aquifer extension whose interior and surroundings are home to fauna and flora
The histochemical is a useful tool in the study of the morphology of various biological tissues (plants and animals) due to its reaction principle of tissue components such as carbohydrates, lipids and proteins, among others, chemical dyes. This valuable tool allows not only to identify the composition and structure of tissues and cells, but also
The heterospory is the development of spores of two different sizes and sexes, in esporofitos of land plants with seeds, as well as in certain mosses and ferns. The smallest spore is the microspore and is male, the largest spore is the megaspore and is female. Heterosporia appears as an evolutionary sign in some plant
The Autophagy is an intracellular degradation system occurs so preserved in the lysosomes of all eukaryotic cells (and vacuoles yeasts). The word is generally used to refer to the degradation of the components of the cytosol or the “parts” of the cell that are “obsolete” or that have stopped working properly. The term autophagy was
Bromelia is a genus of plants native to a tropical area of the American continent called the Guiana Shield in Venezuela, belonging to the Bromeliaceae family. However, plants of other genera of the same Bromeliaceae family are commonly called bromeliad. Plants of the genus Bromeliad are distinguished by having leathery, ribbon-shaped leaves of green and red
The spermatogenesis , spermatic also known as metamorphosis, corresponds to the transformation process spermatids (or spermatids) in mature spermatozoa. This phase occurs when spermatids are attached to Sertoli cells. In contrast, the term spermatogenesis refers to the production of haploid spermatozoa (23 chromosomes) from undifferentiated and diploid spermatogonia (46 chromosomes). The spermatids of a mammal
Populus is a genus made up of a group of tall deciduous trees belonging to the Salicaceae family. Commonly known as poplars or poplars, they comprise an approximate group of 40 species native to the temperate regions of the northern hemisphere. They are fast-growing trees with a closed and oval crown, petiolate, simple and alternate
The thyroglobulin is a protein of 660 kDa consisting of two identical subunits and structurally joined together by noncovalent bonds. It is synthesized by the follicular cells of the thyroid, a process that occurs in the endoplasmic reticulum, is glycosylated in the Golgi apparatus and excreted into the colloid or lumen of the follicles. TSH
The tropomyosin is one of three proteins that are part of the thin filaments in the myofibrils of the muscle cells of the striated skeletal muscle of vertebrates and muscle cells of some invertebrates . It is mainly associated with actin filaments in muscle myofibrils, but there are reports that indicate that, although to a
