How can detergents cause pollution? Phosphates in detergents can lead to freshwater algal blooms that releases toxins and deplete oxygen in waterways. When the algae decompose, they use up the oxygen available for aquatic life. Does Soap pollute rivers? All soaps, unfortunately even biodegradable ones, can contaminate fresh water sources. Materials are usually deemed biodegradable […]
How is Biosphere dependent on all the three spheres?
How is Biosphere dependent on all the three spheres? Answer: The atmosphere is the layer of air that stretches above the lithosphere. The Earth’s water—on the surface, in the ground, and in the air—makes up the hydrosphere. Since life exists on the ground, in the air, and in the water, the biosphere overlaps all these […]
What do all the physical properties of minerals result from?
What do all the physical properties of minerals result from? The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties. What are […]
What instrument can make any sound?
What instrument can make any sound? What instrument can make any sound and be heard but not touched or seen? Your voice. What are examples of idiophones? Idiophones make their sound by hitting, rubbing or shaking. Drums are not idiophones. Neither are stringed instruments. Examples of idiophones include the triangle, wood block, maracas, bell, and […]
What will happen if the chloroplast stops working?
What will happen if the chloroplast stops working? because chloroplasts have chlorophyll, which absorbs energy from the sun. This energy is used for photosynthesis. it also can affect the whole process of photosynthesis the green plant will not be able to carry out the process of photosynthesis which means the plant will die. What will […]
What are the types of LDR?
What are the types of LDR? Light dependent resistors, LDRs or photoresistors fall into one of two types or categories: Intrinsic photoresistors: Intrinsic photoresistors use un-doped semiconductor materials including silicon or germanium. What is the purpose of LDR? An LDR is a component that has a (variable) resistance that changes with the light intensity that […]
What proves light is a particle?
What proves light is a particle? Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Then Max Planck and others were studying the photoelectric effect and they found that certain types of metal and other materials will eject electrons when light shines on […]
Who signs contract first buyer or seller?
Who signs contract first buyer or seller? Once a real estate seller and buyer agree to terms, the seller normally signs a real estate purchase agreement or sales contract. Real estate buyers are generally expected to sign purchase agreements first, though, especially during offer and counteroffer phases. What is a deed consideration? Consideration is a […]

Solute Examples Solute Solution Type of Solution Salt Seawater Solid dissolved in liquid Sugar, dissolved carbon dioxide Soda Solid and gas dissolved in liquid Oxygen, water vapor, carbon dioxide, argon Air Gas dissolved in […]
What will be the magnetic field outside and inside a long current carrying solenoid?
What will be the magnetic field outside and inside a long current carrying solenoid? Outside the solenoid the magnetic field will be weak and the field lines will curl up to form closed loops. Hence, the magnetic field inside a solenoid carrying current will be the same at all the points. What is the value […]
