I HOPE THAT HELPED (: (: (:
Answer: please ask me for help and vote me brainliest :)
The intensity or refraction depends on the material
Explanation:
In the experiment, the purpose it to determine the effect of the material on the refraction index. The refraction index is the ration of the incident ray to the refracted ray. This relationship is known as Snell's law of refraction
where i and r are angles of incident an the refracted ray and n is the refractive index. The dense the material, the more the angle bends. This means that the angle of refraction, as measured by the protractor, is going to be large.
Answer:
Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis, the breakdown of glucose to pyruvic acid.
Explanation:
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
The correct answer is (a) driving.
The pressence of undesirable substances in air is called as air pollution. There are many human activities that contribute to air pollution. The biggest contributor is driving. The pollutants that comes out of the car are carbon dioxide, carbon monoxide. They also release hydrocarbon and nitrogen oxides which when combines in sunlight becomes ozone. Air pollutants emitted by cars and other automobiles increases the level of harmful gases which to severe health problems such as heart disease, asthma, irritation in eyes.
