The planets in our solar system do not travel in circular paths, rather their orbits are elliptical. the sun is located at a focus of the ellipse. the perihelion is the point in a planet's orbit that is closest to the sun. so, it is the endpoint of the major axis that is closest to the sun. the aphelion is the point in the planet's orbit furthest from the sun. so it is the endpoint of the major axis that is furthest from the sun. the closest mercury comes to the sun about 46 million miles. the furthest mercury travels from the sun is 70 million miles. what is the distance between perihelion and aphelion. what is the distance from the center of mercury's elliptical orbit and the sun. write an equation of the elliptical orbit of mercury, where the major axis runs horizontally. allow a and b to be measured in millions of miles. use the origin as the the center of the ellipse. what is the eccentricity of the ellipse, round to the nearest thousandth. what does the value of the eccentricity tell you about the relative shape of the ellipse?

We have enough material to build a fence around a station that has a perimeter of 180 feet the width of the rectangular space must be 3 1/4 feet what must the length be

First to answer all gets a donation question 3(multiple choice worth 1 points) (04.01 lc) which of the following levels is lower than cells in the hierarchy of organization of living things? molecules organs organ systems tissues question 4(multiple choice worth 1 points) (04.01 lc) which of these represents an individual form of life such as an animal, plant, or single-celled life form? organ organism organ system tissue question 5(multiple choice worth 1 points) (04.03 lc) what are the green structures inside plant cells where photosynthesis takes place called? chloroplast mitochondrion nucleus vacuole question 6(multiple choice worth 1 points) (04.03 lc) which of the following best matches a part of a living cell with the function it performs? cytoplasm: fluid which carries the nucleus and other organelles vacuole: fluid which carries the nucleus and other organelles cytoplasm: directs all of the cell's activities vacuole: directs all of the cell's activities question 7(multiple choice worth 1 points) (04.03 mc) read the table below. organelles of plant cells present in both plants and animals present in plants but not animals small in animals but large in plants organelle a organelle b organelle c which statement is most likely correct? organelle a is chloroplast, organelle b is cytoplasm, and organelle c is nucleus. organelle a is mitochondrion, organelle b is cytoplasm, and organelle c is nucleus. organelle a is cell wall, organelle b is chloroplast, and organelle c is mitochondrion. organelle a is mitochondrion, organelle b is chloroplast, and organelle c is vacuole. question 8(multiple choice worth 1 points) (04.03 mc) what will most likely happen in the absence of a nucleus? genetic information will not be transmitted by the cell. energy will not be released during cellular respiration. the cell will not store food, water, nutrients, and waste. the cell will lose its shape and structure.
