science exam review

• Bioluminescence is a form of chemiluminescence.
• A concave mirror is also called a converging mirror.
• A convex mirror always produces a virtual image.
• Microwaves have a longer wavelength and lower energy than visible light.
• A piece of metal glowing red is cooler than one glowing yellow.
• Images in plane mirrors are always virtual.
• Light travels at 3.00 x 10^8 m/s
• Magnifying mirrors are usually concave because concave mirrors form a virtual image that is larger than the actual object.
• Reflection: Light bounces off a substance.
• Incandescent light production: The process of producing light as a result of high temperatures.
• The law of reflection: The angle of incidence is equal to the angle of reflection.
• When light moves from a slow to fast medium it bends away from the normal.
• A normal line: A line perpendicular to the reflecting surface.
• Light always travels in a straight line.
• As an object moves closer to a concave mirror, its reflection will vanish for a moment. That will tell you where the mirror's focus is.
• The refraction of light is the bending of light rays as they pass from one medium to another, which changes the path of the rays.

• Why do diamonds sparkle in the light?

  Light bounces around on the inside of a diamond causing it to sparkle.
• Plant cells have a cell wall, and animals do not.
• Cells that have no specialized function are called Stem cells.
• The function of the vacuole is to store water and nutrients.
• The function of the Golgi Apparatus in a cell is to package proteins
• Cilia and mucus sweep out debris that enters the nose.
• All gas exchanged between air and blood in mammals occurs in the walls of the alveoli.
• Exchange of carbon dioxide and oxygen takes place at the alveoli.
• A majority of the absorption of nutrients occurs in the small intestine.
• The gall bladder stores bile.
• In humans, most digestion takes place in the small intestine.
• Programmed cell death is called apoptosis.
• A mass of cells that continue to divide without any obvious function in the body is called a Tumour.
• Gastric fluids aid digestion and include mucus, HCI, and pepsin.
• Which organ system eliminates waste from the body?

  Excretory System
• Rough muscle is not an example of the muscle types.
• 206 bones in the human body.
• What is the name of the specialized cells that make up the nervous system?


  Neurons
• True or false, the trachea is also known as the windpipe. True
• True or false, the 4 stages of digestion in order are: digestion, absorption of materials, ingestion, and egestion. False
• True or false, cancer cells spend most of their time in mitosis. True
• True or false, hydrochloric acid is used to break down pleura in the stomach. False
• True or false, the large intestine is shorter than the small intestine. True
