Why is it important for the daughter cells to divide a second time in meiosis? Why is it important for the daughter cells to divide a second time in meiosis? The second division forms haploid cells that can combine with other haploid cells during fertilization. Why do you have two sets of chromosomes where did […]
How can we test the properties of matter?
How can we test the properties of matter? Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity. Chemical properties can be measured only by changing a substance’s chemical identity. What do you call everything you own? […]
What are the elements of Geosphere?
What are the elements of Geosphere? The geosphere has four subcomponents: lithosphere (solid Earth), atmosphere (gaseous envelope), hydrosphere (liquid water), and cryosphere (frozen water) (fig. What is the function of geosphere? Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the portion of the earth that includes rocks and minerals. It starts at […]
Which is a significant benefit of studying fossils?
Which is a significant benefit of studying fossils? By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils […]
Does a car have velocity?
What is the relationship between the capacitance and the area of the plates?
What is the relationship between the capacitance and the area of the plates? Larger plates provide greater capacity to store electric charge. Therefore, as the area of the plates increase, capacitance increases. Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. What […]
What are three examples radiation?
What are three examples radiation? Examples of Everyday Radiation Visible light. Infrared light. Near ultraviolet light. Microwaves. Low frequency waves. Radio waves. Waves produced by mobile phones. A campfire’s heat. What is the difference between mass transfer and heat transfer? Mass transfer is physical movement of a body from one place to another. Heat Transfer […]
Are lumps of rocks that orbit the sun?
Are lumps of rocks that orbit the sun? Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do. Meteoroids, especially the tiny particles called micrometeoroids, are extremely common throughout the solar system. How much is a space rock? A prime specimen will easily fetch $50/gram while rare […]
What are the 4 major spheres?
What are the 4 major spheres? Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air). What are the 5 major spheres that interact on Earth? […]
What is partial and total internal reflection?
What is partial and total internal reflection? (i) When light ray travels from denser medium to rarer, reflection takes place partially at the interface, this is called partial reflection. (iv) When the angle of incidence in a denser medium is more than critical angle, the light reflects back into the denser medium. This is called […]
