Different colors of light correspond to different wavelengths. Wavelengths are often quoted in nanometers (nm). The wavelengths of the visible part of the spectrum are shown in the diagram below.According to the diagram, blue-green light would most likely have a wavelength of
What always stays the same when a chemical reaction takes place?
Which of the following is NOT true about sunlight?
In order to protect themselves from being eaten, animals resort to camouflage and chemical defense. Animals camouflage by mimicking the appearance of their environment. Animals that have chemical defenses contain chemicals noxious to predators. Which of these is NOT an example of camouflage or chemical defense?
Osmosis is the movement of water across a selectively permeable membrane in order to equalize the concentration (the amount of protein per milliliter of water) on two sides of the membrane. Consider the diagram below. The container is divided into two compartments, A and B, by a selectively permeable membrane.Each circle represents 100 protein molecules that cant pass through the membrane. The amount of water on two sides of the membrane is initially equal. What will happen as a result of osmosis?
In an acid base reaction, an acid reacts with a base to produce water and a salt. The pH scale can be used to describe the acidity of a liquid. Look at the diagram below. Which two liquids could undergo an acid base reaction?
