Passage excerpt: "Memory is not a single, unified system but rather comprises multiple types that function differently. Short-term memory, also known as working memory, holds information temporarily for immediate use and has a limited capacity of about seven items plus or minus two. Long-term memory is divided into explicit (declarative) memory, which includes episodic memory for personal experiences and semantic memory for general knowledge, and implicit (non-declarative) memory, which includes procedural memory for skills and habits. The hippocampus plays a crucial role in forming new explicit memories, while procedural memories are stored in different brain regions, including the basal ganglia and cerebellum. This distinction explains why people with amnesia, who cannot form new explicit memories, can still learn new motor skills." Complete the notes below. | Type of Memory | Description | Key Brain Region | |----------------|-------------|------------------| | Working memory | Holds info temporarily; capacity of about 7 +/- 2 items | Not specified | | Explicit (declarative) memory | Includes episodic and ______ memory | ______ | | Implicit (non-declarative) memory | Includes procedural memory for skills and habits | Basal ganglia and ______ | | semantic | hippocampus | cerebellum | a) semantic — hippocampus — cerebellum b) hippocampus — semantic — cerebellum c) cerebellum — semantic — hippocampus d) semantic — cerebellum — hippocampus

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: "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: "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: 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: "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: "Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape once it crosses the event horizon. Astronomers classify black holes into three main categories based on their mass. Stellar black holes, formed when massive stars collapse at the end of their life cycles, typically have masses between 5 and 100 times that of the Sun. Supermassive black holes, found at the centers of most galaxies, contain millions or even billions of solar masses. The supermassive black hole at the center of our Milky Way, called Sagittarius A*, has a mass of approximately 4 million suns. A third, less common category consists of intermediate-mass black holes, with masses between 100 and 100,000 solar masses, whose formation process remains poorly understood." Complete the notes below. | Classification of black holes | |---| | Stellar: formed from collapsed ______, 5-100 solar masses | | Supermassive: found at galaxy centers, ______ to ______ solar masses | | Intermediate: 100-100,000 solar masses, ______ remains unclear | a) planets — millions — billions — formation process b) stars — millions — billions — formation process c) stars — thousands — millions — detection method d) galaxies — billions — trillions — formation process

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
