Answer:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

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.
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.

Explanation:
All of the following are advantages of using solar energy except it is a form of coninuous power and it is responsible for it reduces the dependence on fossil fuels. Thus, option B is correct.
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.
Therefore, All of the following are advantages of using solar energy except it is a form of coninuous power and it is responsible for it reduces the dependence on fossil fuels. Thus, option B is correct.

What does it mean when two objects are said to exert a mutual force of attraction?
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.
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.

Outline the pathway of a breath of air from the nose to the alveoli.
Answer:
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Explanation:
Mark as Brainliest Answer
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.

A phase change diagram for water is shown below. The star on the diagram represents the temperature and pressure of some water vapor that a scientist has placed in a special container.
The scientist wants to make changes to the container that will allow the container to have some liquid water, some ice, and some water vapor at the same time. What change should the scientist make to the container?
A.
The temperature should not be changed, but the pressure should be increased.
B.
The temperature should not be changed, but the pressure should be decreased.
C.
The temperature should be increased, but the pressure should not be changed.
D.
The temperature should be decreased, but the pressure should not be changed.
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.

What condition is required for piles of sediment to become a sedimentary rock?
1. Low force
2. High energy
3. High pressure
or 4. Low temperature
Sedimentary rocks are created by the accumulation of already existing rocks or fragments of extinct organisms on the Earth's surface, hence option 3 is correct.
What is a sedimentary rock?Weathering causes rock fragments to become loose, which are subsequently moved to a basin or depression where sediment is trapped.
Sedimentary rock is created when sediment is firmly buried and gets compressed and cemented. Large boulders to tiny clay particles have been found in clastic sedimentary rocks.
The process of erosion involves moving weathering products from the weathering site, either as solid material or as dissolved components, to finally be deposited as sediment.
Therefore, sediment is any unconsolidated accumulation of solid, weathered material to become a sedimentary rock that requires High pressure, hence option 3 is correct.

1.The amount of heat present
2.The amount of water present 2 out of 3 numbers are correct
or 3.The type of minerals that combine
Answer: the answer is (d)
Explanation:
The initial rocks that form an underground rock that was melted and the history of the molten rocks' cooling are the two main elements that affect the formation of igneous rocks.
What factors affect the rock's formation?
After a rock has been fractured, the fragments of rock and minerals are carried away by a process known as erosion.
The type of igneous rocks that form from magma depends on three factors, the chemical composition of the magma, the temperature at which solidification takes place, and the rate of cooling, which affects the crystallization process.
Therefore, factors determine the type of rocks that forms underground forces of weathering and erosion, and Magma's chemical makeup is subject to change.
