I only have 10 points, so.. Sorry. 1. The colors of an opaque object are the result of: refracted light reflected light the light transmitted 2. Sounds which we hear are the result of vibrations True False 3. In the English system, force is measured as: ft. lbs. ft.-lbs. ft.-lbs./sec. 4. A force of 2,500 pounds drags a truck 30 feet in 1/2 minute. How much work is accomplished? How much power was required? Work = 75,000 ft-lbs, Power = 32, 5000 ft-lbs/sec Work = 7,500 ft-lbs, Power = 250 ft-lbs/sec Work= 75,000 ft-lbs, Power = 2,500 ft-lbs/sec 5. The resistance which opposes the motion of moving parts is called ___ inertia friction gravity 6. The "work principle" for real machines can be defined as, "The work accomplished by a machine will always be less than the work needed to operate the machine." True False 7. Mass and weight are essentially the same. True False 8. A single chemical which will not divide into any other simpler substance is: an element a compound a molecule 9. What is "atomic number"? a place in the Periodic Table the number of atoms in a molecule the number of protons in an atom the number of units of atomic weight 10. The atomic weight of an atom is? equal to the number of protons equal to the number of neutrons approximately the number of neutrons plus protons an actual (real) weight of the atom a relative weight

 The plant is at the bottom of the food chain, because it provides energy, or nutrients, for other small organisms such as a grasshopper. The same goes for the grasshopper and the mouse, the mouse and the snake, and it keeps going till the hawk.
  The plant is considered a primary producer, because it provides energy for the grasshopper. However, the hawk is at the top of the food chain, because he is predator. In a way, he can be considered a producer for much bigger animals, but in this case, the hawk is at the top of this chain because he is the main predator in this situation.
 I hope this helps in some way!! Also if you have any other questions let me know! Biology is my FAVORITE subject, and I have multiple notes on this subject! XD
Answer:
plant - grasshopper - mouse - snake - hawk
Explanation:
A food chain shows how energy is transferred from one organism to another in an ecosystem. Arrows point from one organism to the organism that eats it. Photosynthetic organisms, such as plants, are always at the bottom of a food chain. In a desert ecosystem, plants would be eaten by grasshoppers, grasshoppers would be eaten by mice, mice would be eaten by snakes, and snakes would be eaten by hawks. So, the most likely food chain would be:
plant → grasshopper → mouse → snake → hawk

Plate Tectonics
Explanation:
Study Island
Answer:
The direction of winds changes at night especially in coastal areas.
It can be explained with the help of land and sea breezes.
Sea breezes occur during daytime in which cool breezes from the sea flow towards land.
In contrast, during night time the water remains warmer as compared to the land due to which air above the sea gets warmed and become less dense. Consequently, the lighter and warmer air rises and creates a low-pressure zone above the water. Â
It pulls the denser air above the land to the empty space over the water.
Thus, breezes move from land to the sea at night.
Answer:
The answer is indeed Uranus.
Explanation:
Uranus is the third planet furthest from the sun, approximently 1. 784 billion miles away from the sun. Which makes it very cold, Uranus is also the only planet that is upside down, which means that instead of rotating from side to side, it rotates from top to bottom.

Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.
Answer:
Radio waves from space are sensed by a giant parabolic reflector which concentrates them toward the top of a focusing antenna. A radio receptor converts the radio waves into electrical signals which are amplified and then transmitted to the center of the parabola. They are then recorded and analyzed in the laboratory so that scientists can obtain a radio image of the source observed. The parabolic antenna can usually be oriented to detect radio waves from all directions of space.
Answer: Are all different
Explanation:
A classification system is a system of categorizing, organization and naming the organisms or entities in a proper order. The classification system varies according to different subjects, author and utility of classifying the subjects of classification. It is the basis of identification, and grouping of the organisms or entities. Thus all the classification systems are different.
