Answer the following question given this paragraph: Fermat's Principle states that light will always take the path of least amount of time (not distance). This principle governs the paths light will take and explains the familiar phenomena of reflection, refraction, lenses and diffraction. Light rarely travels in a straight-line path. When photons interact with electrons in matter the time it takes for this interaction determines the path. For example, higher frequency blue light is refracted more than red because blue wavelengths interacts more frequently with electrons than red wavelengths and the path of least time is for blue to bend more then red in order to get out of this 'slow' area faster. The rainbows we see are a result of this. Fermat's Principle explains the many fascinating phenomena of light from rainbows to sunsets to the haloes around the moon. Q: Fermat's principle states that light will always take the path of least amount of? A:
****
A: time

Answer the following question given this paragraph: Red algae are a very large group of protists making up about 5,0006,000 species. They are mostly multicellular and live in the ocean. Many red algae are seaweeds and help create coral reefs. Q: Where do most red algae species live? A:
OPTIONS:
- rivers
- lakes
- seas

oceans

Answer the following question given this paragraph: Cerebral palsy is a disease caused by injury to the developing brain. The injury occurs before, during, or shortly after birth. Cerebral palsy is more common in babies that have a low weight at birth. But the cause of the brain injury is not often known. The disease usually affects the parts of the brain that control body movements. Symptoms range from weak muscles in mild cases to trouble walking and talking in more severe cases. There is no known cure for cerebral palsy. Q: Cerebral palsy is a disease caused by injury to what organ as it is developing? A:
OPTIONS:
- heart
- skin
- liver
- brain

Answer: brain

Question: Answer the following question given this paragraph: Catalysts are not reactants, but they help reactants come together so they can react. You can see one way this happens in the animation at the URL below. By helping reactants come together, a catalyst decreases the activation energy needed to start a chemical reaction. This speeds up the reaction. Q: A catalyst decreases the amount of what resource that is required in order to begin a chemical reaction? A:
OPTIONS:
- positive energy
- motion energy
- kinetic energy
- activation energy
Answer: activation energy

input: OPTIONS:
- cartilage
- skin
- mucous
- mantle Now, answer this question: Answer the following question given this paragraph: Mollusks have ventral nerve cords. The tissue beneath the shell is called the mantle. The mantle cavity contains hemolymph. Figure 15.33 Which of the following statements about common features of chordates is true? a. The dorsal hollow nerve cord is part of the chordate central nervous system. In vertebrate fishes, the pharyngeal slits become the gills. Humans are not chordates because humans do not have a tail. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column. Q: What is the tissue beneath a mollusks' shell called? A:
A:
output:
mantle
