A student asks a class the following question, “Polyethylene has a relatively short formula (C2H4) while nylon has a long formula (C12H22N2O2). However, in a toothbrush, the handle is relatively long while the bristles are relatively short. How is this possible?”

Choose the explanation below that best responds to the student’s question.


A
Molecules are so small that they cannot be seen with a naked eye. Therefore, being a slightly bigger molecule on that scale will not influence how big the part of the toothbrush is.

B
In a toothbrush, the polyethylene chain is most likely a longer chain of molecules than the nylon chain, making the handle longer than the bristles.

C
Polyethylene is used for the bristles and nylon is used for the handle, because the size of the molecule does determine the size of the object being built by the molecules.

D
Polyethylene has a short formula, but it makes a long chain. Nylon has a long formula, but it is fat, not long. That is why the nylon bristles are short while the handle is long and thin.

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.

Answers

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.

The answer would be A! :)

Answers

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.
