Do plants take oxygen out of water?
Do plants take oxygen out of water? Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water. At night and on very cloudy days, algae and submerged plants remove oxygen from the […]
What is circumference of cylinder?
What is circumference of cylinder? How do I find the circumference of a cylinder? If you know the cylinder’s radius: Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That’s it; you found the circumference of the cylinder. What is the circumference of a 2 […]
Can you filter out phosphates?
Can you filter out phosphates? Reverse Osmosis is one of the most common and effective methods used for treatment and removal of Phosphates in drinking water. The heart of the system is the Reverse Osmosis (RO) filter that removes contaminants down to 0.0001 microns – so small that only water molecules can squeeze through but […]
What are the major tissues in the respiratory system?
What are the major tissues in the respiratory system? The conducting passageways of the respiratory system (nasal cavity, trachea, bronchi and bronchioles) are lined by pseudostratified columnar epithelial tissue, which is ciliated and which includes mucus-secreting goblet cells. Do lungs have nervous tissue? The lungs are innervated by the parasympathetic and sympathetic nervous systems, which […]
Does intensity depend on amplitude?
Does intensity depend on amplitude? The amplitude of a wave is related to the amount of energy it carries. The average amount of energy passing through a unit area per unit of time in a specified direction is called the intensity of the wave. As the amplitude of the sound wave increases, the intensity of […]
What does a standard blood test check?
What does a standard blood test check? Blood tests can be used for many different things, including to check cholesterol and blood glucose levels.

What are 5 observations?
What are 5 observations? An observation is information we gather about something by using the senses. We have five senses. They include the sense of sight, hearing, taste, touch, and smell. The process of observing is very important to scientists because it helps them learn new things. What is the difference between qualitative and quantitative […]
What is the relationship between S and P waves?
What is the relationship between S and P waves? P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives […]
