Evidence of evolutionLumen Learning

The document provides evidence for evolution from the fossil record, geology, comparative anatomy, biogeography, embryology, and biochemistry. It discusses how fossils are formed through various processes like compression and petrification. Dating methods like relative dating examine rock layers while radiometric dating uses radioactive isotopes to determine absolute ages. Comparisons of homologous and analogous structures in organisms support common descent. Similarities in embryonic development and DNA across species also provide evidence that organisms share a common ancestry.

Mechanisms of Evolution: Population Selection and ChangePaulVMcDowell

The document discusses several key mechanisms of evolution: 1. Mutations introduce new genetic variations within populations. 2. Natural selection leads to changes in populations over generations as certain traits increase chances of survival and reproduction. 3. Gene flow spreads variations between populations through migration and interbreeding. 4. Genetic drift causes random fluctuations in allele frequencies that can accumulate over time, especially in small, isolated populations.

Evolution Science Grade 10jEvz Dacunes-Carbonquillo

This document discusses evidence for evolution from fossil records, comparative anatomy, and genetics. It explains two types of evolution: divergent evolution which causes populations to split into new species, and convergent evolution which causes unrelated species to evolve similar traits from adapting to similar environments. Evidence comes from homologous and analogous structures found in fossils and between species, similarities in embryonic development, and identical amino acid sequences between proteins of different species. Early theories of evolution from Jean Baptiste Lamarck and Charles Darwin are also summarized, including Lamarck's theory of acquired characteristics and Darwin's theory of natural selection.

Causes of Species Extinction There are several threats that can lead to species extinction, including habitat destruction, pollution, overharvesting, and human overpopulation. Deforestation due to kaingin farming and illegal logging destroys wildlife habitats in the Philippines. Water pollution from garbage, factories, and agricultural runoff causes eutrophication and fish kills. Air pollution from vehicle emissions produces smog and acid rain. Coastal destruction from activities like mining, fishing, and development damages coral reefs and mangrove forests. Climate change from greenhouse gas emissions raises global temperatures and endangers many species. Conservation efforts are needed to achieve sustainable development and protect biodiversity.

Cell division - SCIENCE 8Louie Jane Eleccion, LPT

The document discusses cell division and the cell cycle. It defines cell division as the process where a cell divides into two daughter cells. The key stages of the cell cycle are interphase, where the cell grows and DNA replicates, and mitosis, where the cell divides. Mitosis is further broken down into prophase, metaphase, anaphase and telophase. Prophase involves chromosome condensation and nuclear envelope breakdown. Metaphase aligns chromosomes at the center. Anaphase separates sister chromatids. Telophase reforms the nuclei and divides the cytoplasm.

Atoms And Subatomic Particlestnewberry

An atom is incredibly small, with its diameter needing to be increased 200 million times to equal the diameter of a penny. Atoms are made up of subatomic particles, including protons and neutrons in the central nucleus and electrons orbiting the nucleus. Most of an atom's mass comes from its nucleus. The number of protons determines the element and is called the atomic number. Isotopes are atoms of the same element that differ in their number of neutrons.

ConservationEmily Neistadt

This document discusses various methods of natural resource conservation, recycling, and pollution prevention. It emphasizes the importance of reducing waste through reuse and recycling materials like paper, glass, aluminum and plastics. Specific recycling methods are outlined, such as composting food waste and recycling aluminum cans. The document also discusses pollution issues like acid rain, which results from air pollutants, and water pollution from chemicals in pesticides, fertilizers and industrial waste. Overall, the key messages are that conservation, recycling and reducing pollution are necessary to protect natural resources and ecosystems.

Biodiversity Emily Neistadt

Biodiversity refers to the variety of life in an area, including genetic diversity within species, species diversity within biological communities, and ecosystem diversity within biospheres. It increases ecosystem stability and health. There are three components of biodiversity: genetic diversity within populations, species diversity between different types of organisms in a community, and ecosystem diversity between different habitat types. Maintaining biodiversity has direct economic benefits for humans through food, medicine, and other resources, as well as indirect benefits by supporting ecosystem services like oxygen production and water cycling. However, biodiversity is declining rapidly due to threats like overexploitation, habitat loss, pollution, invasive species, and climate change.

Introduction to Theory of EvolutionEmily Neistadt

The document summarizes key concepts about evolution from biology class. It describes how Charles Darwin developed the theory of evolution through his observations on the Galapagos Islands of different finch species with specialized beaks. Darwin proposed that evolution occurs through overproduction of offspring, competition for resources, genetic variations or adaptations, and survival of the fittest. The theory helped explain how the first single-celled organisms evolved over 3 billion years into the diversity of species today through natural selection, mutation, and genetic drift acting on populations.

Surface of the EarthEmily Neistadt

This document discusses processes that shape Earth's surface, including mountain building and erosion. It describes three main ways that mountains form: through folding at convergent plate boundaries, movement of chunks of land at faults, and volcanic activity. Erosion is identified as a major destructive process that causes land and rock to wear down over time. The formation of soil and role of glaciers in shaping the surface are also covered. The document concludes with an overview of the rock cycle and the three main types of rocks: igneous, sedimentary, and metamorphic.

Exploring dominant and recessive traitsEmily Neistadt

This document discusses dominant and recessive genetic traits. It explains that traits are passed down from parents through genes, with each person receiving half their genes from each parent. Dominant traits are stronger and mask recessive traits, while recessive traits only appear in later generations if both parents carry the recessive gene. Common traits like eye color, hair color, and skin pigmentation can be either dominant or recessive. The document includes questions and activities for students to identify dominant and recessive traits in themselves and their classmates.

Patterns of HeredityEmily Neistadt

This document summarizes key concepts in genetics, including Gregor Mendel's experiments with pea plants, dominant and recessive traits, Punnett squares, homozygous and heterozygous organisms, and more complex patterns of heredity such as incomplete dominance, co-dominance, multiple alleles, and polygenic traits. Vocabulary terms are defined including dominant trait, recessive trait, homozygous, heterozygous, purebred, and hybrid. Examples are provided to illustrate concepts like incomplete dominance showing trait blending, co-dominance where two dominant genes are present for one trait, and polygenic traits controlled by many interacting genes.

Earthquakes iiEmily Neistadt

Earthquakes originate from a focus point within the earth and seismic waves travel outward, reaching the surface at the epicenter above the focus. Body waves including P-waves and S-waves originate at the focus and travel through the earth, while surface waves cause more damage when they reach the epicenter. Faults occur along tectonic plate boundaries and are classified as normal, reverse, or strike-slip depending on whether the rocks above the fault plane move down, up, or sideways relative to the other side.

EarthquakesEmily Neistadt

Here are three questions from the section with the answers: 1. What causes convection currents in the mantle? - Convection currents in the Earth are caused by the Earth's hot inner core heating the magma within the mantle. 2. What is a fault? - A fault is a fracture, or break, in Earth's lithosphere. Rocks on either side can slide slowly along the fault or stick together, building stress until releasing in an earthquake. 3. Where do most earthquakes occur? - About 80% of all earthquakes occur in a belt around the edges of the Pacific Ocean, near plate boundaries like the San Andreas Fault where the North American and Pacific plates meet.

Genetics iiEmily Neistadt

This document discusses Gregor Mendel's pioneering work in genetics and heredity by breeding pea plants. It then introduces more complex patterns of heredity beyond Mendel's findings, including incomplete dominance where traits blend, codominance where two dominant genes for a trait are both expressed, multiple alleles where traits have more than two variations, and polygenic traits which are influenced by multiple interacting genes.

Plate tectonics ch 28.2Emily Neistadt

The document summarizes key aspects of plate tectonic theory: 1) Plate tectonics explains the movement of continents and geological events like earthquakes and volcanoes. Early theorists like Alfred Wegener and Harry Hess contributed to developing this theory in the early 20th century. 2) Sea floor spreading was proposed by Hess and coined by Robert Dietz, describing how new ocean crust forms along mid-ocean ridges as the plates spread apart. 3) Magnetic patterns in ocean crust provided evidence that Earth's magnetic poles switch polarity over time, recording a history of plate movements.

Create an earth’s layers posterEmily Neistadt

The document provides instructions for creating an Earth's layers poster by having students 1) diagram and label the layers of the Earth including the inner core, outer core, mantle, asthenosphere, lithosphere, and crust, 2) list and describe each of the 6 layers on a separate sheet of paper, and 3) attach the diagram and description sheets together before turning the poster in, using their book or the Internet for reference.

Chapter 28.1 modern geologyEmily Neistadt

Geology is the study of Earth's rocks and materials. Nicholas Steno developed ideas in the 1600s about how rocks and fossils form using the analogy of shark teeth resembling stones found in rocks. These ideas formed the basis for relative dating techniques. Relative dating determines the order events occurred in by applying principles like superposition, original horizontality, lateral continuity, cross-cutting relationships, inclusions, and faunal succession to analyze rock layers and fossils. Earth's age was originally calculated to be between 10-100 million years but is now estimated at 4.6 billion years based on radioactive dating techniques.

Atoms familyEmily Neistadt

Comparing Atoms and Periodic TableEmily Neistadt

This document discusses atomic structure and the periodic table. It explains that the atomic number is the number of protons in an atom, which distinguishes one element from another. The mass number is the total number of protons and neutrons. Isotopes are atoms of the same element with different numbers of neutrons. Electrons orbit the nucleus in energy levels. The periodic table organizes elements based on their properties and places them in rows and columns according to atomic number.

nervous systemEmily Neistadt

Structure of the nervous systemEmily Neistadt

The document discusses the structure and function of neurons. It describes the five main parts of a neuron - the cell body, nucleus, dendrites, axon, and myelin sheath. Dendrites receive signals and pass them to the cell body, while the axon carries signals to other neurons. A nerve impulse is when a neuron sends a signal, and there are three types of neurons. Neurons transmit signals via action potentials, which travel faster along myelinated axons.

Atomic structure18.1Emily Neistadt

This chapter discusses atomic structure and the development of atomic models from Dalton to Schrodinger, including Thomson's discovery of electrons, Bohr's model of electrons orbiting the nucleus in fixed orbits, and Schrodinger's electron cloud model showing electron location is probabilistic rather than definite. The chapter also defines subatomic particles like protons, neutrons, electrons and their relative masses and charges, and introduces concepts like atomic number, isotopes, and the periodic table which are explored further.

Political History of Pala dynasty Pala Rulers NEP.pptxArya Mahila P. G. College, Banaras Hindu University, Varanasi, India.

The Pala kings were people-protectors. In fact, Gopal was elected to the throne only to end Matsya Nyaya. Bhagalpur Abhiledh states that Dharmapala imposed only fair taxes on the people. Rampala abolished the unjust taxes imposed by Bhima. The Pala rulers were lovers of learning. Vikramshila University was established by Dharmapala. He opened 50 other learning centers. A famous Buddhist scholar named Haribhadra was to be present in his court. Devpala appointed another Buddhist scholar named Veerdeva as the vice president of Nalanda Vihar. Among other scholars of this period, Sandhyakar Nandi, Chakrapani Dutta and Vajradatta are especially famous. Sandhyakar Nandi wrote the famous poem of this period 'Ramcharit'.

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder

Introduction All the materials around us are made up of elements. These elements can be broadly divided into two major groups: Metals Non-Metals Each group has its own unique physical and chemical properties. Let's understand them one by one. Physical Properties 1. Appearance Metals: Shiny (lustrous). Example: gold, silver, copper. Non-metals: Dull appearance (except iodine, which is shiny). 2. Hardness Metals: Generally hard. Example: iron. Non-metals: Usually soft (except diamond, a form of carbon, which is very hard). 3. State Metals: Mostly solids at room temperature (except mercury, which is a liquid). Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid). 4. Malleability Metals: Can be hammered into thin sheets (malleable). Non-metals: Not malleable. They break when hammered (brittle). 5. Ductility Metals: Can be drawn into wires (ductile). Non-metals: Not ductile. 6. Conductivity Metals: Good conductors of heat and electricity. Non-metals: Poor conductors (except graphite, which is a good conductor). 7. Sonorous Nature Metals: Produce a ringing sound when struck. Non-metals: Do not produce sound. Chemical Properties 1. Reaction with Oxygen Metals react with oxygen to form metal oxides. These metal oxides are usually basic. Non-metals react with oxygen to form non-metallic oxides. These oxides are usually acidic. 2. Reaction with Water Metals: Some react vigorously (e.g., sodium). Some react slowly (e.g., iron). Some do not react at all (e.g., gold, silver). Non-metals: Generally do not react with water. 3. Reaction with Acids Metals react with acids to produce salt and hydrogen gas. Non-metals: Do not react with acids. 4. Reaction with Bases Some non-metals react with bases to form salts, but this is rare. Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc). Displacement Reaction More reactive metals can displace less reactive metals from their salt solutions. Uses of Metals Iron: Making machines, tools, and buildings. Aluminum: Used in aircraft, utensils. Copper: Electrical wires. Gold and Silver: Jewelry. Zinc: Coating iron to prevent rusting (galvanization). Uses of Non-Metals Oxygen: Breathing. Nitrogen: Fertilizers. Chlorine: Water purification. Carbon: Fuel (coal), steel-making (coke). Iodine: Medicines. Alloys An alloy is a mixture of metals or a metal with a non-metal. Alloys have improved properties like strength, resistance to rusting.
