Answer:
Explanation:
Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas.
Answer:
<em>The correct option is D) Diane will have to travel a farther distance to move the chair.</em>
Explanation:
To slide the chair up an inclined path, Diana would have to travel a further distance. While using the ladder to reach the second floor window would have made the distance smaller, but more force would have been required to move the chair through climbing a ladder. Diane would have got easily exhausted for moving the chair across the ladder. Using the inclined path will make the distance farther but as much force would not be required in this process. Hence, the method of using an incline is better.
Answer: Cellular respiration is the process by which microorganisms obtain the energy available in carbohydrates. They take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrate and release the energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen gas is identical to the oxygen gas given off in photosynthesis.
Explanation:
Dependent reaction is the factor that is observed and measured
