(a) because aluminium is a soft malleable metal. it can be made to in sheets to form thin wrapping sheets. also, it does not react with food items.
(b) because metals are good conductors of heat and electricity. the immersion rod needs electric supply to get heated and to heat liquids.
(c) they're kept in kerosene to keep them from coming in contact with oxygen and moisture as they react to form their hydroxides.
4. Magnesium is a metal. Metals react with oxygen to form metallic oxides. So Magnesium oxides are basic in nature. But nonmetals react with oxygen to form nonmetallic oxides. These oxides differ from metallic oxides because they are acidic in nature. Nonmetallic oxides react with water to form acids. Therefore, Sulphur dioxide is acidic in nature. Magnesium oxide is basic in nature.
5. Copper forms a green deposit on its surface when exposed to air which is usually a mixture of copper carbonate and copper hydroxide. It's acidic in nature.

Which winds blow steadily from specific directions and over long distances? _________
Answer: hot air
hot air
cool air
Explanation:
The wind blows cool air inland during the day is sea breeze.
The wind blows cool air toward the sea at night is land breeze.
The winds blow steadily from specific directions and over long distances are global winds.
What are the global winds ?The term global wind is defined as winds that occur in belts that go all around the planet. Earth is hottest at the Equator and gets cooler toward the poles.
Global winds are winds that blow steadily from specific directions over long distances. Warm air rises at the equator and sinks at the poles, causing winds to blow from the poles to the equator at the earth's surface.
In a sea breeze the cold air travel from sea towards land during daytime and in a land breeze the cold air travel from land towards sea during night time.
Thus, The winds blow steadily from specific directions and over long distances are global winds.

The figure of speech is hyperbole and through it, the reader can infer that Seabiscuit is a very fast horse.
What is a hyperbola?A hyperbole is a figure of speech that allows a term within the text to be emphasized through exaggeration. In the text above, we can see that the narrator claims that Seabiscuit is the fastest horse in the universe.
This is an exaggeration, since there are no horses in the entire universe, nor would it be possible to determine which is the fastest. However, this exaggeration serves to show the reader how fast Seabiscuit is, despite its physical structure.In the text above, we can see that the narrator claims that Seabiscuit is the fastest horse in the universe.
Therefore, The figure of speech is hyperbole and through it, the reader can infer that Seabiscuit is a very fast horse.

Rosa drew a flow chart of the carbon cycle.
Flow chart of the carbon cycle with 4 boxes connected by arrows. Box 1: carbon dioxide in the atmosphere. Box 2: X. Box 3: consumers eat producers. Box 4: Y. The arrow that follows box 4 connects to box 1.
Which labels best complete the flow chart?
A
X: Producers undergo photosynthesis.
Y: Decomposers return carbon to the soil and release waste.
B
X: Decomposers return carbon to the soil and release waste.
Y: Producers undergo photosynthesis.
C
X: Decomposers take in carbon dioxide.
Y: Producers absorb carbon through their roots.
D
X: Producers absorb carbon through their roots.
Y: Decomposers take in carbon dioxide.
The correct Answer is A.
The Flow chart of the Carbon Cycle, will look as follows:
1. Carbon dioxide in the atmosphere.
2. Producers undergo photosynthesis (in this process plants among other producers like algae, use CO2 to produce energy).
3. Consumers eat producers (a primary level of consumer like a rabbit eats the producers or plants).
4. Decomposers return Carbon to the soil and release waste.
And the cycle continues again, by going back to step 1.
