c. to drain underground lakes where minerals are found
d. to create strip mines and quarries below the surface of the earth
The function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.
What is subsurface mining?Subsurface mining is the process in which mineral ores are too deep to extract at with this mining techniques, subsurface mining methods are used .
An advantage and good thing of subsurface mining is that it will not disturb land than surface mining it only disturbs less than one-tenth the surface amount of land as surface mining and the method.
Therefore, the function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.

4. What would most likely be the result of an invasive species entering an ecosystem?
5. Why are humans responsible for many invasive species?
#4: An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts
#5: It is not surprising that human population density is a leading cause of species invasions. Species are easily moved by human and animal (particularly domestic animal) vectors, and increasing populations residing next to protected areas simply means increasing the odds of species introduction

is used by television stations for pictures
Which headings best complete the chart?
A) X: Phase, Y: Pulse
B) X: Pulse, Y: Phase
C) X: AM, Y: FM
D) X: FM, Y: AM
In the electromagnetic spectrum, the headings which best describe the chart are X: FM, Y: AM.
What is electromagnetic spectrum?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Write a paragraph on why food needs to be digested. :)
Please hurry I need it.
Answer: You die if no digest
Explanation:
Food needs to be digested because your body can't contain large stuff whole, so it has to be converted into a smaller amount. For Instance, if you were to eat a entire turkey then your body would just explode I guess if you wouldn't digest it. Also, without digesting food you can't enter new food into your body. Therefore, this is why food needs to be digested.

A scientist is investigating which type of medicine would dissolve faster, a solid pill or a scoop of powder. Which hypothesis should the scientist develop given prior knowledge about surface area?
A.
Powders have more surface area and will dissolve faster.
B.
Solid pills have less surface area and will not dissolve.
C.
Solid pills have more surface area and will take longer to dissolve.
D.
Powders have less surface area and will dissolve faster.
Answer:
A.
Powders have more surface area and will dissolve faster.
Explanation:
please mark this answer as brainlest
The solute-like solids can dissolve in the solvent through the dissolution process. Powders have more surface area that permits more dissolution.
What is surface area?The surface area is the amount of space covered or occupied by an object. It is directly dependent on the solubility and increases with an increase in the solubility.
The surface area of the powder is more compared to the solid pill and hence, the solubility of the scoop of powder is more than the pill.
Therefore, powder dissolves faster because option A. has more surface area.

Explain the flow of energy in the food chain and why stored energy is an important concept of it.
Answer:
"The process of transfer of energy to various trophic level of food chain is known as flow of energy. Energy flow in ecosystem from energy source to autotrophs to heterotrophs."
Explanation:
The energy flow from the primary members, plants to the other level of organism in food chain. Storage of energy is very important because, the stored energy in plants are distributing to all other levels in food chain and utilizing for activities.
What is energy distribution in food chain ?The sun is the main source of energy for practically all ecosystems on earth. Energy moves from one trophic level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose.
Primary producers are then consumed by primary consumers, who are in turn eaten by secondary consumers, and so on. The sun is the main source of energy for practically all ecosystems on earth.
Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose. Only 10% of energy is distributed to the other level and 90% are lost to the surroundings.

The local newspaper has published the passage below.
Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.
Which statement in the news passage above is inaccurate?
The aurora australis cannot be seen from space.
