Relative Sizes (Earth, solar system, Milky Way galaxy, local super cluster, universe) Relative Distances It the sun shrank to 1mm (grain of sand) then earth would be 11cm away, Pluto would be 4 meters and the nearest star would be ajax If the entire solar system shrank to 1mm one side of the milky way…
Star: A large ball of glowing gas that generates heat and light, through nuclear fission in its cove. Our sun is a star. Planet: any of the nine large celestial bodies in the solar system that revolves around the sun and shine by reflected light. Moon (or satellite): the natural satellite of the Earth.…
The evolution of the star: Stars are born out of clouds of gas and dust. A star generates energy by converting hydrogen into helium deep in the centre (the core). As most of the hydrogen turns into helium in the core, the core runs out of “fuel”. The core contracts under pressure and becomes hotter…
Formation: Differences between disk and halo: –Orbits of stars, ages of stars, the metal contents in stars, and the amount of gas and dust are all different Current theory suggests that the Galaxy formed from an enormous cloud of gas (the Protogalactic Cloud) The halo and the first generations of stars formed as this cloud…

(chromosome= reduction) Fertilization: nuclei of egg/ sperm fuse; producing zygote (# chromosomes typical…
Genetic linkage: genes located on same chromosome may be inherited together in genetic crosses. Linked Genes: Genes on same chromosomes Morgan- first to map genes; can’t directly measure distance between genes Do it indirectly– gene sitting far apart on a chromosome would be more likely to be separated from one another during meiotic crossing-over than…
Blending theory of inheritance: hereditary trait blend evenly in offspring through mixing of parent’s blood. Mendel studied heritable characteristics called characters; plant color and seed shape. Variation in character= Trait Monohybrid cross between to heterozygous parents (Dr x Dr) F1 generation will yield phenotypic ration of 3:1 (1/4 getting PP or pp, or ½ getting…
