Scrubbers is another name for Flue gas desulfurization equipment. Flue gas desulfurization equipment reduce the impact of coal use by removing sulfur dioxide in flue gas from fossil-fuel power plants and from the emissions of other sulfur oxide emitting processes. Power plants use flue gas desulfurization equipment to remove impurities such as sulfur, nitrogen oxides and other particulates from smoke before it goes away from their smokestacks.
Answer:
This question is incomplete; the question is asking to identify variables such as the DV, IV, Constants etc
Independent variable (IV): Type of flowers
Dependent variable (DV): Growth of flowers
Constants: the same amount of sunlight, same amount of water
Explanation:
The independent variable is the variable that an experimeter changes or manipulates deliberately in order to bring about an effect in another variable. In this experiment, the TYPE OF FLOWER on each soil is changed by Alex, hence, it is the independent variable.
Dependent variable is the variable that is being measured in the experiment. It is the variable that responds to the changes made to the independent variable. In this case, the dependent variable is the GROWTH OF THE FLOWERS measured.
Constansts or control variable is the variable that the experimenter keeps constant or unchanged throughout the experiment in order to maintain the outcome of the experiment. In this case, the constants are the same amount of light, same amount of water
Answer:
Slump creep and weathering
Explanation:
Freeze-thaw weathering occurs when water from rainfall or melt snow penetrate into cracks and the temperature is lowered than a liquid and freeze. The process where exposed rock is broken. It gives the landscape a new shape.
When the freeze occur it expands the rock and when the temperature increases above freezing the thaw ice further penetrate into the crack.
Weathering the breaking down of rock into smaller frequent affects freeze-thaw as it allows water to penetrate into cracks.
Slump is the downward movement of materials from rock surface, it allows material to move alone the rock surface liquid such as water can be allowed to move and penetrate cracks. crack rock fragment that results from freeze thawing are deposited at rock base and form smaller rocks
Creep is also the movements of weathered materials down the slope of rock surfaces. It could result from freeze thaw.
The right option is; nucleotides
Nucleotides are the building blocks of DNA macromolecules.
Nucleotides are the building blocks (monomers) that make up a DNA molecule. Each nucleotide that constitutes DNA has three components which are; a five-carbon sugar (ribose or deoxyribose), a nitrogenous base, and a phosphate group. Nucleotides perform several important roles in the cell. They transfer chemical energy to cellular functions that require energy such as in proteins synthesis, and in the movement of the cell. Nucleotides are also involved in cell signaling.
