Open-pit mining creates a large hole in the ground after minerals are removed from the surface. Which statement best describes an environmental consequence of this process?
Heavy metals are released into surrounding soil, poisoning local vegetation.
High salinity of wastewater reduces soil fertility and growth of vegetation.
Billions of gallons of water are pulled from surrounding ecosystems.
Wastewater is contaminated with oil and becomes sludge in landfills.
Answer: (A) Heavy metals are released into surrounding soil, poisoning local vegetation.
Explanation: Open-pit mining falls under the surface mining category in the lesson 01.07 page 3/8 under the affects of surface mining the only one that is in the multiple choice questionnaire is "Heavy metals are released into surrounding soil". (don't know how much this helps since I'm 7 days late but hey this is a new curriculum and I've had trouble finding answers on brainy so why not contribute for once ¯\_(ツ)_/¯ )
The correct statement that best describes an environmental consequence of open-pit mining is that heavy metals are released into the surrounding soil, poisoning local vegetation.
The large hole left by open-pit mining becomes filled with water during heavy rains with heavy metals dissolving in the water to form solutions.These solutions percolate the surrounding soil and when they are taken up by the vegetation on the soil, the plants become poisoned by the heavy metals.In other words, the hole created by open-pit mining serves as an avenue for heavy metals to get into the surrounding soil and gets into the food chain through the plants.

How will a solution change if a base is added?
The hydroxide ion concentration will decrease and lower the pH.
The hydroxide ion concentration will decrease and raise the pH.
The hydrogen ion concentration will increase and lower the pH.
The hydroxide ion concentration will increase and raise the pH.
Answer:
As the concentration of hydrogen ions in a solution increase, the more acidic the solution becomes. As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. ... Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls, and vice versa.

what is Monosaccharide?
Answer:
A Monosaccharide is just the simplest form of sugar. It's general term applied to a sugar that cannot be broken down into anything 'simpler'. A great example of this is glucose. Glucose cannot be hydrolized to form anything else, but there are more complex forms of glucose like glycogen. Glycogen is basically a bunch of glucose molecules bonded together and used as "stored glucose", but glycogen can be hydrolized to form individual glucose molecules (monosaccharides).

The body systems that would immediately get involved with my reaction to the cut are nervous system, circulatory system, integumentary system. That is option A
The systematic factors that are required for wound healing after sustaining a cut in the finger include:
The nervous system: here the nerve cells in the skin help wounds to heal. When an injury occurs, cells known as glial cells change into repair cells and disseminate into the wound, where they help the skin to regenerate.The circulatory system: The cut surfaces become inflamed and blood clot and cell debris fill the gap between them. Phagocytes from the blood stream, begins to remove the clot and cell debris stimulates fibroblast.The integumentary system: the skin contains extracellular matrix (ECM) which is made of collagen and elastic fibres that provide structure to the skin and are necessary for wound closure.Learn more here:

What similarities, if any, do you think exist between a human’s reproductive cycle and the life cycle of a fern? What differences, if any, can you think of?
Answer:
The similarity between ferns and humans is that both go through meiosis and mitosis. But ferns are different because they have multicellular, free-living haploid and diploid forms. In humans, the haploid stage exists in the form of single cells—sperm and eggs. Only the diploid stage that begins with a zygote grows mitotically to form a multicellular, free-living human.
Explanation:
Humans and ferns are similar as both of these organisms fertilize to reproduce while differs in the haploid form of life which is present in the ferns and the male and female reproductive parts present in humans.
What is the life cycle of a fern?
The life cycle of fern includes the diploid fern which gives rise to the haploid spores that grows and form a gametophyte plant in which both the male and female reproductive systems are present. The male gamete undergoes fertilization with the female gamete to form a diploid spore (seed) which gives rise to the new fern plant.
Human’s reproductive cycle include diploid animals and the male and female genders which can be distinguished clearly. The male gamete-sperm fertilizes with the female gamete-egg to form the diploid zygote that gives rise to a new human.

On a graph, the vertical axis is
the y-axis and the horizontal
axis is the x-axis. Onəwhat axis
should the INDEPENDENT
VARIABLE be placed?
A
on the vertical or y-axis
B
on the horizontal or x-axis
Answer:
x-axis
Explanation:
you control those values/variables
On a cartesian plane, the independent variable belongs on the x-axis.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
The independent variable is the variable that is being manipulated or controlled in an experiment, and its values are typically plotted along the horizontal or x-axis.
The dependent variable, which is the variable being measured or observed in response to changes in the independent variable, is usually plotted on the vertical or y-axis.
This convention allows us to easily visualize and analyze the relationship between the two variables.
therefore, The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid
Answer:
by feeding on the organism on the previous level, the consumers at each level will receive energy. However, most of the energy is lost at each trophic level and very little gets transferred from one trophic level to another. Approximately, 10% of the energy is transferred from one trophic level to another.
Explanation:
hence, when a level takes energy from a previous level, the engery transfers but slowly gets less, so some levels get less energy depending on where the engery was located.
