Passage excerpt: Einstein's theory of special relativity, published in 1905, fundamentally changed our understanding of space, time, and energy. The theory is based on two postulates: first, the laws of physics are the same in all inertial reference frames; second, the speed of light in a vacuum is constant for all observers, regardless of their motion or the motion of the light source. From these postulates follow several counterintuitive consequences. Time dilation means that a clock moving at high speed ticks more slowly relative to a stationary observer. Length contraction means that objects moving at high speed appear shortened in the direction of motion. The famous equation E equals mc squared expresses the equivalence of mass and energy. Complete the notes below. Postulate 1: Laws of physics are the same in all ______ Postulate 2: Speed of light is ______ for all observers Time dilation: Moving clock ticks ______ than stationary clock Length contraction: Objects appear ______ in direction of motion E equals mc squared: ______ and energy are equivalent Word box: inertial reference frames, constant, more slowly, shortened, mass a) inertial reference frames - constant - more slowly - shortened - mass b) constant - inertial reference frames - shortened - more slowly - mass c) mass - more slowly - inertial reference frames - constant - shortened d) shortened - mass - constant - inertial reference frames - more slowly

Passage excerpt: "An ecosystem is a community of living organisms interacting with each other and their physical environment. Ecosystems can be as large as a desert, forest, or ocean, or as small as a pond or a rotting log. The living components of an ecosystem are called biotic factors, including plants, animals, and microorganisms. The non-living components are called abiotic factors, such as sunlight, temperature, water, soil, and air. Energy flows through ecosystems in food chains and food webs, starting with producers (plants and algae) that convert sunlight into energy through photosynthesis. Consumers (herbivores, carnivores, and omnivores) eat other organisms, and decomposers (bacteria and fungi) break down dead organic matter, returning nutrients to the environment." Complete the notes below. | Ecosystem components | |---| | Biotic factors: plants, animals, and ______ | | Abiotic factors: sunlight, temperature, water, soil, and ______ | | Energy starts with ______ that perform photosynthesis | | ______ break down dead matter and return nutrients | a) microorganisms — air — producers — decomposers b) fungi — water — consumers — producers c) plants — soil — consumers — decomposers d) animals — temperature — producers — consumers

Passage excerpt: "Carbon capture and storage, or CCS, is a process for capturing carbon dioxide emissions before they enter the atmosphere and storing them underground. The three main stages of CCS are capture, transport, and storage. Capture can be achieved through post-combustion capture, where CO2 is separated from other gases after burning fossil fuels; pre-combustion capture, where fuel is converted into a mixture of hydrogen and CO2 before burning; and oxy-fuel combustion, where fuel is burned in pure oxygen rather than air, producing a flue gas that is mostly CO2 and water vapor. The captured CO2 is then transported via pipeline to a storage site, where it is injected deep underground into geological formations such as depleted oil and gas fields or saline aquifers, where it is trapped by impermeable rock layers." Complete the notes below. | Carbon Capture and Storage process | |---| | Capture methods: ______ capture, pre-combustion capture, oxy-fuel combustion | | CO2 transported via ______ to storage sites | | Stored underground in depleted ______ fields or saline aquifers | | Trapped by ______ rock layers | a) post-combustion — pipeline — oil and gas — impermeable b) pre-combustion — ship — coal and gas — porous c) post-combustion — truck — oil and gas — impermeable d) oxy-fuel — pipeline — renewable — impermeable

Passage excerpt: "The Industrial Revolution, which began in Britain in the late 18th century, brought about significant changes in manufacturing, transportation, and social structure. Before this period, most people lived in rural areas and worked in agriculture. The establishment of factories led to rapid urbanization, as people migrated from the countryside to cities in search of work. By 1851, more than half of Britain's population lived in urban areas for the first time in history. This massive demographic shift created new social challenges, including overcrowded housing, poor sanitation, and pollution, which were documented by contemporary observers such as Friedrich Engels and Charles Dickens." Complete the notes below. Choose ONE word only from the passage for each answer. Notes: Urbanization during the Industrial Revolution - Most people previously lived in ______ areas. - Factories attracted workers to ______. - By 1851, over half of Britain's population was ______. - Social problems included overcrowding and ______. a) rural — cities — urbanized — pollution b) agricultural — towns — industrialized — noise c) countryside — factories — metropolitan — disease d) farming — centers — populated — waste

Passage excerpt: "Cells are the basic structural and functional units of all living organisms. There are two main types of cells: prokaryotic and eukaryotic. Prokaryotic cells, found in bacteria and archaea, lack a nucleus and membrane-bound organelles. Their DNA exists as a single circular chromosome in the cytoplasm. Eukaryotic cells, found in plants, animals, fungi, and protists, have a membrane-bound nucleus that houses their DNA, as well as various organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Plant cells have additional structures not found in animal cells, including a rigid cell wall made of cellulose, chloroplasts for photosynthesis, and a large central vacuole for storage." Complete the notes below. | Comparison of cell types | |---| | Prokaryotic cells: no ______, no membrane-bound organelles | | Eukaryotic cells: have ______ that houses DNA | | Plant cells have ______ for photosynthesis | | Plant cells have a rigid ______ made of cellulose | a) cell wall — cytoplasm — mitochondria — cell membrane b) nucleus — a nucleus — chloroplasts — cell wall c) mitochondria — a vacuole — cell wall — chloroplasts d) nucleus — cytoplasm — chloroplasts — cell membrane

Passage excerpt: "The practice of urban gardening has gained momentum in cities worldwide as residents seek to reconnect with nature and reduce their carbon footprint. Community gardens provide green spaces in densely populated areas, foster social connections between diverse groups, and improve air quality. Studies have shown that neighborhoods with active gardening programs report lower stress levels among residents and stronger community bonds. Additionally, locally grown produce reduces the distance food travels from farm to table, decreasing greenhouse gas emissions associated with transportation." Complete the notes below using words from the box. | benefits | locations | problems | costs | advantages | |----------|-----------|----------|-------|------------| Urban gardening in cities offers several ______. These gardens are situated in ______ and provide environmental and social ______. a) advantages — locations — benefits b) problems — costs — advantages c) benefits — locations — advantages d) costs — advantages — problems

Passage excerpt: "Chemical bonds hold atoms together to form molecules. The three main types of chemical bonds are ionic, covalent, and metallic. In an ionic bond, one or more electrons are transferred from one atom to another, creating positively and negatively charged ions that attract each other. This typically occurs between a metal and a nonmetal. In a covalent bond, atoms share pairs of electrons. This usually occurs between two nonmetals. Covalent bonds can be single (one shared pair), double (two shared pairs), or triple (three shared pairs). In a metallic bond, electrons are delocalized and move freely among a lattice of metal atoms, which explains why metals conduct electricity and are malleable." Complete the notes below. | Types of chemical bonds | |---| | Ionic bond: electrons are ______ from one atom to another | | Covalent bond: atoms ______ pairs of electrons | | Metallic bond: electrons are ______ and move freely | | Ionic bonds typically occur between a ______ and a nonmetal | a) transferred — share — delocalized — metal b) shared — transferred — free — nonmetal c) delocalized — shared — transferred — metal d) transferred — shared — ionized — nonmetal

Passage excerpt: "Migratory birds navigate across thousands of kilometers using a remarkable combination of navigation methods. Some species use the Earth's magnetic field as a compass, detecting magnetic lines that run from the poles to the equator. Others rely on the position of the sun and stars, adjusting their flight direction based on the time of day. Some birds also use landmarks such as rivers, mountains, and coastlines to guide their journeys. Scientists have discovered that certain birds, like the European robin, possess a protein called cryptochrome in their eyes, which may allow them to literally 'see' the Earth's magnetic field as visual patterns." Complete the notes below using words from the box. | magnetic | landmarks | visual | sound | cryptochrome | position | Migratory birds use multiple navigation methods. They detect the Earth's ______ field, adjust direction based on the ______ of the sun, and use geographical ______ like rivers and mountains. Some birds have a protein called ______ that may allow them to perceive the magnetic field as patterns. a) magnetic — position — landmarks — cryptochrome b) sound — position — visual — landmarks c) visual — magnetic — landmarks — cryptochrome d) magnetic — sound — landmarks — position
