Examples: Cadastral maps, topographical maps….A map bearing a scale of 1: 4000 and larger is called : Cadastral map. Topographical map. Wall map. Atlas map. […]
How do you interpret mean median and mode in research?
What are all the structures in cytoplasm?
What are all the structures in cytoplasm? It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm. Which […]
Are the layers still horizontal or are they bent Why?
Are the layers still horizontal or are they bent Why? Answer. Answer: Figure 10.6: Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. How is horizontal unconformity formed? An angular unconformity is an unconformity where horizontally parallel strata […]
What 3 types of EM waves are dangerous to humans?
What 3 types of EM waves are dangerous to humans? The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them. How long does it take for gamma rays to kill you? Most deaths occur within […]
Who has proved that oxygen evolved in photosynthesis comes from water?
Who has proved that oxygen evolved in photosynthesis comes from water? Cornelius van Niel Which light range is most effective in photosynthesis? The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the […]
What is the difference between control variable and independent variable?
What is the difference between control variable and independent variable? Independent variable – the variable that is altered during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results. What is the different types of variables? Parts of […]
What is the main cause of ozone depletion?
What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
Why is gravity a non-contact force?
Why is gravity a non-contact force? Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the […]
Why does more bandwidth mean more data?
Why does more bandwidth mean more data? To transfer data, a signal must change in some way and the rate at which these changes occur influences the rate at which information can be transferred. Thus, more bandwidth corresponds to a higher maximum rate of data transfer. How do I know my Internet bandwidth? How To […]
