Biodiversity. 19
1. What is biodiversity?
It is the totality of species and ecosystems of a region, including the entire genes.
2. Morphological What are adaptations?
There are anatomical structures that guarantee the individual a more harmonious relationship with their environment.
3. Physiological adaptations What are and what are its types?
Are changes in the individual organ function, enabling them to better suit the environment, their types are body temperature and fruit ripening.
4. What is Convergent Evolution?
It is when different groups of animals or plants develop similar structures in response to similar environmental pressures.
5. What is adaptive convergence?
They are different groups of organisms that develop a similar adaptation.
6. What is divergence?
It is when the species belonging to the same group of animals or plants are adapted to different lifestyles.
7. What is Adaptive Radiation?
is the evolution of a single ancestral species giving rise to species that differ in body parts.
8. What is Co-evolution?
Is evolution resulting from the interaction between interdependent species, in which a special adaptations give rise to another.
9. Levels of Biodiversity.
Son 3: genes, species and ecosystems.
10. What is Genetic Diversity?
It is the variation of genes within species.
11. What is Species Diversity?

The total number of species found in a given region.
12. What is ecosystem diversity?
Are the different coping mechanisms that have allowed the diversification of life in the different terrestrial habitats.
13. What are Extinct Species?
Represents the disappearance of species of flora and fauna.
14. What are Endangered Species?
They are the species whose population range has decreased dramatically.
15. What are Endangered Species?
Species are in danger of disappearing in the medium term.
16. What are Rare Species?

Are species that are naturally rare, very sensitive to the presence of human beings and they tend to decrease rapidly.
Classification of living things. 20
1. Summary of leading scientists made the first q classifications.
The primitive humans began classifying animals and plants as dangerous and not dangerous, edible and inedible. In the fifth century Aristotle and his followers tried to classify approx. 1000 species known at that time. They were classified "top level" of animals and plants, and "second tier" to the new groups found eg plants were divided into trees, shrubs and herbs. Among the criteria employed by Aristotle to classify species can be named: extrinsic criteria such as presence or absence of red blood; intrinsic criteria such as number of legs and presence or absence of eggs.
This divided the animals:
Red-blooded animals (vertebrates): subgroups: four-legged creatures small breed, animals that are eggs, feathered bipeds, Nicknames.
Red bloodless animals (invertebrates): subgroups, cephalopods, crustaceans, molluscs, echinoderms, insects.

This classification was used for over 1000 years. In the middle ages there were books called bestiary, with incorrect information about animals. In the sixteenth century, Konrad von Gesner published a book called History animaliun
2. What is binomial nomenclature and what are their characteristics?
It is a classification system in which each species is assigned two names to represent it. Features:
· Considers the species as the fundamental taxonomic unit.
· For each species denotes a scientific name in Latin and Latinized Greek, which consists of two names: the genus and specific epithet. The genre began with the epithet is case sensitive.
· Makes the grouping of species in each taxonomic categories more spacious look.
· Use a uniform scientific terminology.
3. What is Systematics?
Is a branch of biology that studies the types of life on earth, their biodiversity and their phylogenetic relationships. It is perhaps more complete in the field of biology studies.
4. How the scheme brings to life forms?
It comprises the closely related species in genera, genera into families, families into orders, the orders into classes, classes in phyla, and phyla into kingdoms.
5. What aspect of the systematic q takes into account the modern classification of living things and which takes into account?
The German biologist Ernst Haeckel proposed fu q in the first three kingdoms: animal, plant and protist, in 1959 Robert H. Whittaker proposed the division into five kingdoms: Monera, protists, fungi, animals and plants. Recently, thanks to advances in biochemistry, genetics and the molecular biology, proposed the existence of seven kingdoms: two prokaryotes (bacteria and Eubacteria tonnage) and five eukaryotes (protozoa, CROM, plant, animals and fungi). There is a kingdom of red algae and green algae q can not be classified within the CROM or within plants
6. "Outline the classes of each of the kingdoms?
· Archaebacteria: extreme halophytes, methanogenic, thermoacidophilic
· Eubacteria: heterotrophic, autotrophic, chemotrophs
· Protozoa: archamoeba, diplomonadia, kinetopastida, euglenas
· CROM: Oomycota, Bacillariophyta, Chrysophyta, xantophyta, Phaeophyta,
· Red algae and green algae: Rhodophyta (red algae), Chlorophyta (green algae)
· Hong: Chytridiomycota, Zygomycota, Basidiomycota, Deuteromycota, Ascomycota.
· Plants:
i. non-vascular plants: Bryophyta, Hepatophyta, hornwort.
ii. Vascular Plants: Seedless: psilophyta, Lycopodiopsida, sphenophyta, pteridopsida, with seeds:
1. Gymnosperms are divided into Coniferophyta, cycadophytes Gnetophyta.
2. Angiosperms that have a division, antophyta.
· Animals: simply divide in vertebrates in invertebrates. The invertebrates are divided into phylum Rotifera, phylum Porifera, phylum Cnidaria, phylum Platyhelminthes, phylum Nematoda, phylum Annelida, phylum Mollusca, phylum Arthropoda, phylum Echinodermata, and q phylum chordata subphylum is divided into three: subphylum Urochordata, subphylum Lancelet, subphylum vertebrata q and is divided into seven classes: class Agnatha, class chondrichtyes, Osteichtyes class, class amphibia, class Reptilia, birds class, class Mammalia.
