Which statement best describes how this puddle demonstrates that matter is too small to be seen without magnification?
The light causes a reflection to appear on the surface of the water.
The person cannot see the bottom of the puddle.
The twig floats on top of the puddle of water.
The water cannot be seen when it evaporates.
Answers
Answer:
The twig floats on top of the puddle of water.
Explanation:
The twig will almost seem like magic. Because water is clear its hard to understand matter holding the twig up. But under a microscope you are able to see the qualities of water and the building blocks of matter.
The twig floats on top of the puddle of water best describes how this puddle demonstrates that matter is too small to be seen without magnification. The correct option is C.
Thus, The inability of the individual to see the puddle's bottom proves that the matter (in this case, the water's constituent particles) is too small to be seen without a magnifying glass.
Because the water droplets are so tiny and tightly packed, light cannot penetrate through the puddle to expose its bottom.
This finding emphasizes how tiny the individual particles are that make up matter.
Thus, The twig floats on top of the puddle of water best describes how this puddle demonstrates that matter is too small to be seen without magnification. The correct option is C.

What is fossil fuel?
A fossil fuel has been hydrogen that contain the material found in the nature in the earth's crust from the remain of the dead plants and animals that has been extracted and burned as the fuel. Fossil are natural source of energy, it is made from decomposition of plants and animals. Fossil fuels are found in the earth's crust and it must contains carbon and hydrogen which could gives energy by the burning. Natural gas usually found in pockets above oil deposits. It is also found where natural oil is found.
Coal, oil including natural gas are the best examples of the fossil fuels. Coal has been a material usually found in the sedimentary rock deposits where rock and plants are buried from long time. Oil has been originally found as the solid material between layers of sedimentay rocks, like shale. This material has been heated and converted into a gasoline.

Answers
The temperature should be decreased, but the pressure should not be changed.
What is Temperature and Pressure relation ?In contrast, as a gas's pressure falls, its volume rises as a result of the gas's ability to spread its particles farther apart. Because the volume of the gas has risen, weather balloons become larger as they ascend through the sky to lower pressure areas.
This is because when the atmospheric gas exerts less pressure on the balloon's surface, the inside gas expands until the internal and external pressures are equal.
Some of the early studies that established the quantitative relationship between the pressure and volume of a gas were done by the Irish chemist Robert Boyle (1627-1691).
Therefore, The temperature should be decreased, but the pressure should not be changed.

Air travels through the following structures on its path to the alveoli (the site of gas exchange): nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles.
What is breathing?The trachea (windpipe), which is further separated into bronchial tubes, receives it from there. Bronchioles are another division of the bronchial tube, the little alveoli structure is where the bronchioles eventually come to a stop.
Through our noses, we breathe air into our bodies, after then, it moves via the larynx, pharynx, and nasal cavity before entering the windpipe, also known as the trachea.
Therefore, air enters both lungs through bronchi that branch off of the trachea.

can someone make a story about calcium? pls help me
Answers
Answer:
um a story about Calcium? sure... Pls mark me brainliest!
Explanation:
Calvin Calcium was strong. Calvin Calcium was sturdy. Calvin Calcium had very good teeth. He
was a happy little boy and drank all of his Phenyl-Free. But one day all that changed. Here’s what
happened…
“I’m not going to drink my ‘milk’ any more,” said Calvin one morning at breakfast.
“Oooh,” said his mother, “then you can get your calcium from green, leafy
vegetables.”
“No,” said Calvin, “I’m not going to eat green, leafy vegetables either.”
“Oooh,” said his mother, “what will happen to Calvin?”
It wasn’t too long before Calvin found out.
In May, it was time for Calvin to have his dental check-up.
“Oooh,” said the dentist, “you have four cavities, Calvin. Have you
been eating foods with lots of sugar? Have you been forgetting to brush your teeth?
Maybe you haven’t been eating enough foods that give you calcium.” The dentist
filled the four cavities, and Calvin’s teeth were fine again. Calvin didn’t mind—too
much.
But in July, Calvin and his friends, Fred and Linda, were
building a tree fort.
They were almost done when, whoops, Calvin lost his balance and
tumbled to the ground!
“My arm hurts!” wailed Calvin.
“Oooh,” said his mother, running from the kitchen, “we’d better go
to the doctor!”
Doctor Smith felt Calvin’s arm very carefully.
“Oooh,” said the doctor, “you have a broken arm, Calvin.”
He put Calvin’s arm in a cast, and Calvin couldn’t go out to play for a long
time. He missed splashing in Fred’s pool to get cooled off on hot days. He
missed Linda’s birthday party. They played lots of neat games and had his
favorite low protein foods. But most of all, he missed playing with his friends.
He could hear them playing ball and roller skating every day.
Calvin went back to the doctor because it was
taking so long for his arm to heal.
“Oooh,” said the doctor, “it looks as if you haven’t been
eating foods with lots of calcium to make your bones strong.”
The Calvin Calcium Story
One morning Calvin said to his mother, “I’d like some of my ‘milk’ for breakfast.”
So that morning Calvin drank his ‘milk’. It tasted very good.
At lunch, Calvin said, “I’d like some green, leafy vegetables, please.”
So that noon, Calvin had green, leafy vegetables. They tasted very good too.
At dinner, Calvin said, “I’d like some green, leafy vegetables AND some ‘milk’, please.”
So Calvin had collard greens and lots of his ‘milk’ for supper. How good they tasted!
Calvin’s arm was almost healed now. Soon he would be able to join his
friends at the pool, on skates, and in their ball games.
When Calvin went to the dentist that fall, he had only one cavity. Calvin said
he had been brushing his teeth after eating AND eating foods that give him
calcium, especially his ‘milk’.
Calvin was again a strong, sturdy, happy boy—with very good teeth and strong bones!

Interestingly, calcium seems to come in fifth place wherever it goes: It is the fifth most abundant element by mass in the Earth's crust (after oxygen, silicon, aluminum and iron); the fifth most abundant dissolved ion in seawater (after sodium, chloride, magnesium and sulfate); and the fifth most abundant element in the human body (after oxygen, carbon, hydrogen and nitrogen). It is, however, the most abundant metallic element in the human body, 99 percent of which can be found in our bones and teeth (about 2 lbs. of it!), according to Chemicool.
In its pure elemental state, calcium is a soft, silvery-white alkaline earth metal. It is important to note, however, that calcium is never found in this isolated state in nature, but exists instead in compounds. Calcium compounds can be found in a variety of minerals, including limestone (calcium carbonate), gypsum (calcium sulfate) and fluorite (calcium fluoride), according to Chemicool. Calcium makes up about 4.2 percent of the Earth's crust by weight.

In order to isolate pure calcium, it must be extracted through electrolysis, a technique that uses a direct electrical current to separate elements from their naturally occurring sources. Once isolated, calcium is quite reactive and will form a grayish-white oxide and nitride coating when exposed to air.

Calcium (Ca) is No. 20 in the periodic table of the elements, appearing just below magnesium in the same column (Group IIA) as the other alkaline earth metals (a group of metals that are more chemically reactive than most metals). Calcium comes from the Latin word "calx," meaning lime. This is not a reference to the fruit, but rather calcium oxide (CaO), the useful building material derived from heated limestone.
Calcium is extremely important to the human body. Not only is it vital for bones and teeth, but it assists in muscle movement by carrying messages from the brain to all our body parts. Cells in all living things must communicate with, or "signal," one another. Calcium ions act as vital messengers between these cells and are necessary in all multicellular life forms. They also assist in the release of hormones and enzymes.
In food, calcium is found in mineral form. Foods high in calcium include dairy products — such as milk, cheese and yogurt — and some vegetables, such as kale, watercress, spinach and broccoli. In order for calcium to absorb properly, it should be taken with vitamin D. Magnesium is also necessary for proper assimilation and use of calcium in the body. In fact, if we take too much calcium and not enough magnesium, it can cause problems in the body.
Lime, or calcium oxide, produces a brilliant, intense light when exposed to an oxyhydrogen flame, according to Chemicool. In the 1800s, before electricity was invented, this substance was used to light up the theater so actors truly performed "in the limelight" — hence the saying.
When turtles (typically pet turtles) don't have enough calcium circulating through their blood, they may get an ailment called Metabolic Bone Disease, commonly known as Soft Shell Syndrome. For a turtle to be healthy, the calcium to phosphorous ratio should be 2:1. When their calcium levels are low, however, the mineral is leached from their bones in the body's attempt to balance things out. The result is soft bones, weakness and a soft, deformed shell, and it often results in death. The disease can be prevented with a proper diet and adequate sunlight (or other appropriate lighting for reptiles).
Stalactites and stalagmites, the icicle-shaped formations found in underground caverns, are formed slowly over time by the build-up of calcite residue. This occurs when water seeps through the cracks in the ceiling of a limestone cave, dissolving and carrying along traces of calcite, the building material of limestone. As the water drips from the ceiling, this calcite residue begins to build up at the site of the drip, eventually resulting in icicle-shaped stalactites hanging from the cave ceiling. This water dripping from the stalactites then forms stalagmites on the ground

A. Each takes turns attracting the other. B. They attract each other at the same time.
C. A third object takes turns attracting each of them.
D. A third object attracts them both at the same time.
Answers
Answer:
B
It says "mutual", so both objects are attracting at the same time. In addition, I do not believe it is possible for objects to take turn acttracting each other so I believe A is false. I think C and D are wrong because a third object is not related to any of these choices. It also explicitly states "two objects" and when it says mutual, it means they are attracting each other.
Two objects are described below.
Thing 1: It pulls things down toward the ground.
Thing 2: It takes the shape of a container.
Which statement is true?
A Both objects are matter.
B Both objects are non-matter.
C The first object is matter, and the second object is non-matter.
D The first object is non-matter, and the second object is matter.

Answer:
D. The first object is not-matter, and the second object is matter.
Explanation:
The first object is gravity, this force pulls things toward the ground. The second object is something I don't know, but it is matter.
hope this helps.
The first object is matter, and the second object is non-matter.
The description provided for each object helps us determine whether they are matter or non-matter.
Thing 1: "It pulls things down toward the ground."
This description implies that Thing 1 has gravitational force, which is a characteristic of matter. Matter is anything that has mass and occupies space. Objects with mass, like planets, people, and all physical substances, exhibit gravitational force. Therefore, Thing 1 is a form of matter.
Thing 2: "It takes the shape of a container."
This description indicates that Thing 2 can fill the space within a container and assume its shape. Matter is capable of taking the shape of its container, whether it's a liquid, gas, or solid. This property is a fundamental characteristic of matter. Therefore, Thing 2 is also a form of matter.
Option A, "Both objects are matter," is incorrect because both Thing 1 and Thing 2 are indeed matter, as explained above.
Option B, "Both objects are non-matter," is incorrect because the descriptions provided for both Thing 1 and Thing 2 indicate that they possess properties of matter.
Option C, "The first object is matter, and the second object is non-matter," is also incorrect, as both objects are matter based on their respective descriptions.
Option D, "The first object is non-matter, and the second object is matter," is not true based on the explanations provided for both Thing 1 and Thing 2.
In conclusion, both Thing 1 and Thing 2 described in the statements are forms of matter due to their properties and characteristics associated with matter.
