How long does it take for one drop of acetone to evaporate? How long does it take for a drop of acetone to evaporate? Acetone evaporates rapidly, even from water and soil. Once in the atmosphere, it has a 22-day half-life and is degraded by UV light via photolysis (primarily into methane and ethane.) Which […]
Which of the following is or are properties of life?
Which of the following is or are properties of life? Properties of Life. All groups of living organisms share multiple key characteristics or functions: order, sensitivity or response to stimuli, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life. What are the properties associated […]

What happens to the kinetic energy store when an object slows down?
What happens to the kinetic energy store when an object slows down? The object’s energy is slowly transferred from the kinetic store to the gravitational potential store as it slows down and climbs higher. Once the object reaches its highest point, all of its energy is in the gravitational potential store. During this process, energy […]
Does V stand for frequency?
Does V stand for frequency? The symbol v is generally used for the frequency of electromagnetic waves; whereas, the symbol f is generally used for the frequency of ordinary waves that require a material medium, such as sound and water waves. The period of the wave is the time lapse between crests (or between troughs). […]

What is the difference in an area with high concentration and an area with low concentration?
What is the difference in an area with high concentration and an area with low concentration? In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion. A physical space in which there is a different concentration of a single substance is said to […]
What type of infections do neutrophils fight?
What type of infections do neutrophils fight? Neutrophils have a well-established role during fungal and extracellular bacterial infections where they promote bacterial clearance through phagocytosis, production of reactive oxygen and nitrogen species (ROS/RNS), neutrophil extracellular trap (NET) formation, and production of pro-inflammatory cytokines (6, 7). Do neutrophils fight bacterial infections? Neutrophils are an important component […]
Is Circumcenter always inside triangle?
Is Circumcenter always inside triangle? The circumcenter is not always inside the triangle. In fact, it can be outside the triangle, as in the case of an obtuse triangle, or it can fall at the midpoint of the hypotenuse of a right triangle. See the pictures below for examples of this. Which two points of […]
