Evolution is the process of change that has transformed life on Earth from its earliest beginnings to the diversity of organisms living today. Fundamental organizing principle in biology and core theme.
Biology study of life, poses questions about living organisms & uses scientific inquiry through its study
Some properties of Life:
Order sunflower
Energy processing Ingestion and processing of nutrients Butterfly and flower
Growth and development Inherited info in genes controls it Seed into plant
Evolutionary adaptation Sea horse camouflage overtime…
Regulation Rabbits ears
Response to environment Venues fly trap
Reproduction Jiraffe with offspring
Organization-New properties emerge at successive levels of biological organization
From biosphere to molecules-Emeergent properties, Structure and Function-Cell basic unit of life displays both.
Information-:Life processes Involve the Expression and transmission of genetic info.
DNA the genetic material. Genomics: large scale analysis of DNA Sequences
Énergy and matter-Life requires the transfer and transformation of energy and matter
Producers and consumers-Energy flow and chemical cycling
Interactions-From ecosystems to Molecules Interactions are important in Biological Systems
Ecosystems:An organism Interacts Interactions with other organisms
Molecules:Interactions within organisms-Feedback regulation
Evolution-The Core theme of Biology-scientific explanation for diversity and shared features as well as adaptation of organism to their environments
1-Apreciar la importancia del estudio de La biodiversidad
Evolution evolutionary mechanisms- accounts for the unity and diversity of life
Classifying the Diversity of Life-trying to make sense of variety
2-Conocer los niveles de organización biológica-, grouping by shared characteristics, before gropupings by careful; comparisons of structures , functions and other obvious features. Now comparisons of DNA, debate about kingdoms, agreement in domains.
DOMAIN Eukarya
KINGDOM Animalia (6-12)
PHYLUM Chordata
CLASS Mammalia
ORDER-Carnivora
FAMILY-Ursidaed
GENUS-Ursus
SPECIES-Ursus Amricanus
3- Discutir los 3 Dominios del Árbol de la Vida
Domain BACTERIA-are the most widespread PROKARIOTES & are now classified into multiple kingdoms
Domain ARQUEA-PROKARYOTES live in Earths extremes environments such as salty lakes and boiling hot springs MK
Domain EUKARYA-includes three kingdoms of multicellular EUKARYOTES
Kingdoms Plantae Kingdom Fungi Kingdom Animalia-Distinguished partly by mode of nutrition
Kingdom PLANTAE-consist of terrestrial multicellular EUKARYOTES (land plants) that carry out photosynthesis. The conversion of light energy to chemical energy in food. They produce their own sugars and other food molecules through photosynthesis.
Kingdom FUNGI-absorb dissolved food nutrients from their surroundings or outside their bodies
Kingdom Animalia consist of multicellular EUKARYOTES that ingest food by eating and digesting other organisms. Consumers.
PROTIST are mostly unicellular Eukaryotes (and some relatively simple multicellular relatives) some more related to plan animals and fungi than to other protist. (Trend split into several kindoms.)
(Unity-Ex Cilia in Paramecium in pond water and cilia in human windpipe cells)
4-Mencionar las características generales que definen los dominios
5-Reconocer los niveles de clasificación de los organismos vivos
6-Identificar los pasos del método científico
In studying nature, scientists make observations and form tests hypotheses
Scientists use a process of Inquiry that includes making observations, forming logical and testable explanations (hypothesis)
Making Observations
They collect Data or information in which a hypothesis is based-qualitative, quantitative
Co0llecting and analysing data and observations Can lead to important logical general conclusion through inductive reasoning and make predicitons that can be used to test a hypothesis.
Forming and testing hypothesis
hypothesis is, a tentative answer To. A well framed question, must be testable, through exp or observations
deductive reasoning LOGIC FROM GENERAL TO SPECIFIC form prediction that will result what will be found through a particular hypothesis
an experiment is a scientific test carried out under controlled conditions
controlled experiments are to demonstrate the effect of one variable by testing control groups and experimental groups that differ only on one variable
theory is broad in scope generates new hypothesis an is supported by a large body of evidence
Vocabulario:
Diversitiy-hall mark of life and also of unity. The number and variety of organisms found within a specific geographic region or environment & earth between species and within and between ecosystems
Diversidad-variedad de especies vivos que viven en un lugar.
Taxonomy-a scientific discipline concerned with naming and classifying the diverse forms of life
Taxonomía-disciplina científica que nombra y clasifica las diversas formas de vida
Eukaryote-an organism with eukaryotic cells. They are made up of cells of membrane enclosed nucleus and membrane enclosed organelles. The domain Eukarya includes 3 kingoms at a multicellular level:Kingdoms Plantae, Fungi and Animalia, distinguished by their modes of nutrition. Single celled Eukaryotes protists numerous and diverse
Prokaryote-organisms with prokaryotic cells (Bacteria and ARCHAE), A TYPE OF CELL LACKING A MEMBRANE… ENCLOSED NUCLEUS AND MEMBRANE ENCLOSED ORGANELLES.
DOMAIN-taxonomic category above the kingdom level. The 3 Domains are Archea Bacteria Eukarya
Dominio-categoria taxonómica sobre el nivel de Reino. Los 3 Dominios son Arquea Bacteria Eukarya
Kingdom- a taxonomic category, the second broadest after domain
Reino-una categoría taxonómica, la segunda más amplia después de Dominio
Bacteria-another prokaryotic domain, the other one being Archea
Bacteria-el otro dominio prokariotico, el otro siendo Arquea
Archea one of two prokaryotic domains the other one being Bacteria
Arquea-Uno de Los dominios prokarioticos el otro siendo bacteria
Fungi is defined
