Robert is baking a cake. The instructions tell him to weigh all the ingredients before mixing. He has 100 g of eggs, 100 g of water, and 250 g of flour. He decides to weigh the cake after baking. It weighs 425 grams. He is confused by the results. Which answer supports what happened during the mixing and baking process.
A. Baking is a closed system, so he must have mismeasured. None of the reactants left the system.
B. Baking is an open system, so he must have mismeasured. None of the reactants left the system.
C. Baking is a closed system, so he measured correctly. Some of the reactants may have left the system.
D.Baking is an open system, so he measured correctly. Some of the reactants may have left the system
Answer: C.Baking is a closed system, so he measured correctly. Some of the reactants may have left the system.
Explanation : baking is a closed system and he probably didnt measure wrong so i think in the baking it lost some.

When an El Niño occurs, there is less wind in an area. This results in less upwelling, which in turn does not bring nutrient-rich, cold water to the surface. This has a negative impact on people who make their living from fishing. Lesson 2.12 Question 1 options: True False
When an El Niño occurs, there is less wind in an area. This results in less upwelling, which in turn does not bring nutrient-rich, cold water to the surface. This has a negative impact on people who make their living from fishing. This statement is true.
What happens when El Niño occurs?El Nio occurs when surface water in the equatorial Pacific warms above average and east winds blow weaker than usual. La Nia is the opposite condition. The water is cooler than usual during this phase of ENSO, and the east winds are stronger. El Nios occur every 3 to 5 years on average.
Trade winds weaken during El Nio. Warm water is pushed back east, toward the Americas' west coast.
During El Nio, the upwelling of cooler oceanic water along the South American coast decreases. The trade winds typically move from South America to Asia/Australia, dragging warm surface water away from the coast while colder, nutrient-rich water rises to shallow depths.
Thus, This has a negative impact on people who make their living from fishing. This statement is true.

Write a short paragraph about electrical current using the terms conductor and insulator.
Answer:
Bet
Explanation:
In a conductor, electric current can flow freely, in an insulator it cannot. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. ... Most atoms hold on to their electrons tightly and are insulators.

Answer:
1.They generate power only from the kinetic energy of moving water (current).
2.relating to the motions of fluids or the forces which produce or affect such motions — compare hydrostatic.
3. It uses water motion to generate a high-pressure liquid rather than electricity.
4. tidal currents, ocean currents or river currents into electrical power.
5.When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.
