It defines a polygon as a closed figure formed by line segments that intersect only at endpoints. Polygons are classified as regular, irregular, convex, or concave. Common polygon names are provided for up to 12 sides. Formulas are given for calculating the sum of interior and exterior angles based on the number of sides of the polygon.
types of angles.pptx
This document defines different types of angles and their measurements. It explains that an angle is formed by two rays with a common endpoint called the vertex. The main types of angles are acute, right, obtuse, straight, reflex, and 360° angles. Acute angles are less than 90°, right angles are 90°, obtuse angles are greater than 90° but less than 180°, straight angles are 180°, reflex angles are greater than 180° but less than 360°, and 360° angles span the entire circle. Examples and definitions are provided for each type of angle.

Cognitive load theory
Cognitive load theory describes the different types of cognitive load on working memory: intrinsic load from the difficulty of the material, extraneous load from poor instructional design, and germane load that aids learning. Various instructional design techniques can manage cognitive load, such as worked examples, completion problems, integrating rather than splitting sources of information, presenting words and pictures together rather than separately, and eliminating redundant information. The effectiveness of techniques depends on learner expertise and the complexity of the material.

2.6 acids bases and salts
This document discusses acids, bases, and salts. It defines pH and the pH scale, explaining that acids have a pH below 7 while bases have a pH above 7. Neutral solutions have a pH of 7. Acids contain H+ ions while bases contain OH- ions. When an acid and base react, they form a salt and water through neutralization. Common acids and bases are given along with examples of acid-base reactions and properties. Methods for making soluble salts by reacting acids with metals or insoluble bases are also described.
C2.5 exothermic and endothermic reactions
This document discusses exothermic and endothermic chemical reactions. It provides examples of common exothermic reactions like combustion and oxidation, which release energy to their surroundings. Endothermic reactions like the decomposition of calcium carbonate absorb energy from their surroundings. The document uses examples like hand warmers and sports injury cold packs to illustrate exothermic and endothermic processes. It also contains questions to test the reader's understanding of whether specific reactions are exothermic or endothermic.
C2.3.3 quantitative chemistry
Farmer Giles wants to determine which fertilizer contains more nitrogen. To do this, he needs to calculate the percentage of nitrogen by mass in each fertilizer. KNO3 has a higher percentage of nitrogen than NaNO3 because KNO3 has a lower molar mass and therefore more of its mass is made up of nitrogen. Calculating percentage by mass involves using relative atomic masses and molar masses. For example, the percentage of nitrogen in ammonia is calculated by taking the mass of nitrogen atoms, dividing by the molar mass of ammonia, and multiplying by 100.
C2.2 how structure influences
Substances with simple molecular, giant ionic and giant covalent structures have very different properties. Ionic, covalent and metallic bonds are strong, while forces between molecules are weaker. Nanomaterials have new properties due to their small size on the scale of 10 atoms. The structures of substances influence their properties and uses.
C2.1 structure and bonding
1. The document discusses different types of chemical bonding including ionic bonding, covalent bonding, and metallic bonding.
2. Ionic bonding involves the transfer of electrons between atoms to form ions with opposite charges that are attracted in a giant lattice structure.
3. Covalent bonding can form either simple molecules held together by shared electron pairs or giant covalent structures with thousands of atoms bonded together.
C2.1 structure and bonding
Ionic compounds form giant lattice structures when oppositely charged ions bond via electrostatic forces. This ionic bonding results in high melting points and the ability to conduct electricity when molten or dissolved. Covalent bonds involve electron sharing and can form either simple molecules with weak intermolecular forces or giant covalent structures with very high melting points due to numerous strong covalent bonds. Metallic bonding involves delocalized electrons that act as glue between positive metal ions, allowing them to slide past one another.
B2.8 speciation
Speciation is the formation of new biological species. The document provides three key points about speciation and its relationship to natural selection:
1. Speciation can occur when a single population becomes separated into two isolated groups. Over time, each group evolves differently through genetic variation and natural selection, resulting in reproductively isolated species.
2. Evidence for evolution includes the fossil record, which shows organisms changing over time and new species arising as others become extinct.
3. Natural selection plays a role in speciation when environmental changes cause isolated populations to evolve adaptations better suited to their local conditions, leading to reproductive isolation and the formation of new species over prolonged periods of separation.
B2.7 meiosis and mitosis
Meiosis and mitosis are two types of cell division. Meiosis occurs in sex organs and produces gametes through two divisions, resulting in four cells each with half the number of chromosomes, while mitosis occurs throughout the body and involves one division to produce two identical cells with the same number of chromosomes. The main differences are that meiosis produces gametes and reduces chromosome number, while mitosis produces somatic cells to grow and repair tissues.
B2.7 genetic disorders
This document discusses several genetic disorders including polydactyly, cystic fibrosis, and Huntington's disease. It provides details on the inheritance patterns and characteristics of each disorder. Potential treatments and ethical issues related to genetic testing, gene therapy, cloning, and preimplantation genetic diagnosis are also examined.
B2.7 cell division and inheritance
Cell division and inheritance allow characteristics to be passed from parents to offspring. Chromosomes, made of DNA and containing genes, are found in cell nuclei and segregate into gametes during meiosis. Offspring receive half their chromosomes from each parent, determining traits like earlobe attachment and sex, which is determined by XX or XY sex chromosomes. Genetic crosses can predict the likelihood offspring will inherit dominant or recessive alleles.
B2.5 proteins enzymes
Enzymes are protein molecules that act as biological catalysts, increasing the rate of chemical reactions. They are specific and only catalyze one reaction. Enzymes are found in animals, plants and microorganisms and are used widely in the home and industry. Some advantages of using enzymes include enabling reactions to occur at lower temperatures and making industrial processes cheaper. However, enzymes are sensitive to temperature and pH changes.
Aerobic & anaerobic respiration
Aerobic respiration uses oxygen to break down glucose, releasing energy. This occurs in mitochondria and produces significantly more ATP than anaerobic respiration. During intense exercise, the body shifts to anaerobic respiration which takes place in the cytoplasm when oxygen demand outstrips supply. It generates lactic acid and ATP more quickly but to a lesser extent. The human body repays this oxygen debt through deep breathing after exercise to oxidize lactic acid buildup.
B1.4 red v grey
Environmental changes affect the distribution and survival of both plant and animal species through biotic and abiotic factors. Biotic factors like competition for resources and disease transmission have led to changes in species populations over time, such as the disappearance of pollinating insects and the decline of red squirrel numbers in the UK due to the introduction and spread of grey squirrels who outcompete reds for food and carry squirrel pox virus to which they are immune but kills reds. Non-biotic environmental changes in temperature, oxygen levels, water, and light availability from sources like pollution have also impacted species distributions.
B1.4 pollution detectors
Lichens are useful as bio-indicators of pollution levels because they absorb nutrients and pollutants from the air. Different lichen species show varying sensitivities and abilities to accumulate pollutants. They can survive in almost all environments and seasons. Indicator species found in water can also indicate pollution levels, with mayfly nymphs and caddis fly larvae found in cleaner water, and water lice and sludgeworms found in more polluted water, allowing conclusions about water quality to be drawn. Samples should be taken at the same time each year for valid comparisons, and other factors like oxygen, pH, metals or chemicals can also act as non-biological pollution indicators.
B1.4 plants adaptation
Plants have developed various adaptations to survive in different environments. Some plants in cold climates are small, dark-colored, and have small waxy leaves or needles to minimize heat loss. Desert plants often have silver or hairy leaves to reflect sunlight, store water in stems or leaves, or have deep root systems to reach water underground. Adaptations help plants acquire resources and endure environmental stresses.
B1.4 animals adaptations
This document discusses animal adaptations for survival in different environments. It provides examples of how Arctic and desert animals have adapted through physical traits like thick fur or thin coats and body shapes that minimize heat loss or gain. Sharks are used to demonstrate both general aquatic adaptations like streamlined bodies and gills as well as specific predatory adaptations like sensitive smell and replaceable teeth. Surface area to volume ratio is discussed as an important factor in an animal's ability to retain or shed heat.
