Salt is most likely to be mined using which mining technique?
A.) Mountaintop removal
B.) Solution mining
C.) Placer mining
D.) dredging
Answer:
B.) Solution Mining
Explanation:
Definintion: solution mining is mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water.
Sorry if it's wrong!
=> Solution mining is done by pumping water into subterranean salt deposits, found in many parts of the world, dissolving the salts and pumping the brine to the surface for drying and further use.

An investigation involving osmosis and plant cells was performed by a group of students. Sweet potatoes were used as
the source of plant cells in the experiment. A sweet potato was diced into evenly sized andshaped cubes and placed
in beakers containing various glucose concentrations. The experimental setup is shown in the table here.
Which statements accurately predict the beaker in which water will enter the cells at a greater rate, causing an
Increase in mass for the sweet potato cells?
A)
Beaker 1
B)
Beaker 3
C) beaker 4
Answer:
A
Explanation:
Water will enter and leave the cells at the same rate via osmosis
The correct option is (A) Beaker 1 in which water will enter the cells at a greater rate, causing an increase in mass for the sweet potato cells.
What is Osmosis?Osmosis refers to a process in which the water or solvent diffuse across a semipermeable membrane (here cell membrane) from the area of high solute (here glucose) concentration to low solute concentration. The concentration of glucose in the water of beaker 1 is 1.5M which is highest as compared to other beakers.
The concentration of glucose solution in beaker 1 is hypertonic to the concentration of glucose in the cell which makes the water to move inside the cell via osmosis. Movement of water inside the cell results in increase in mass for the (sweet potato) cells.
Thus, the water will enter the cells at a greater rate in the beaker 1 because the glucose concentration is highest in the beaker 1 corresponding to its cell glucose concentration.

In which of the following situations does the cell use active transport?
Answer: The correct option is B. Sodium ions move into the cell from areas of lower concentrations.
Explanation:
Active transport can be described as a process in which molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Energy is required for the process of active transport to occur.In the option B, sodium ions are moving into the cell from areas which have a low concentration of sodium i.e against the concentration gradient. Hence, option B tells that the sodium ions will move inside the cell by the process of active transport.

Answer:
Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity. Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity.
Explanation:
Muscle tissue has four distinct properties: excitability, contractility, extensibility, and elasticity.
What are muscles?The human body contains approximately 600 muscles. Skeletal, smooth, and cardiac muscles are the three primary types of muscle.
The neuromuscular system is the collaboration of the brain, nerves, and skeletal muscles to end up causing mobility.
Muscle fibers are highly specialized cells that make up the muscular system. Their main function is contractility.
Movement is governed by muscles, which are attached to bones or vital organs and blood vessels. Muscle contraction causes nearly all movement in the body.
Muscle tissue is distinguished by characteristics that enable movement. Muscle cells are excitable, meaning they respond to stimuli.
They are contractile, which means they can simplify and produce a pulling force. When muscles are attached between two movable objects, such as two bones, they contract.
Thus, these are the three physiological concepts associated with muscular tissues.
