Think about the manipulated variable as the changing item in the experiment. If this changes, the response will. (This is the Independent Variable)
Think of the Responding Variable as the result of the variable only can change when Manipulated is changed. (This is the Dependent Variable)
Hope This Helps :)
Manipulated variable in each case are watering of plants, number of chocolates, trees having leaves,water in acid rain, amount of calcium respectively and responding variables are growth height, amount of homework,number of bird nests,fish population,bone strength.
What are variables?Variables are defined as any characteristics, number or quantity which can be measured . It can also be called as a data item . It is called as variable because they can vary and can have variety of values.
There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variable which do not change
Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

Which of the above organisms gets its energy from photosynthesis?
Only I
Only IV
I, II and III only
I, II, III and IV
Answer:
grass
Explanation:
it is a plant, hope this helps
Answer:
Only I
Explanation:
rabbits and foxes are not plants so it does not go through photosynthesis (they eat food to get their energy instead) . A mushroom is a decomomposer that breaks things down to get it's energy thus make the grass the only plant that goes through photosynthesis.

Scientists hope to use aerogels to aid in oil spill cleaning process by floating aerogels on water where oil has been spilled. For this to occur how would the density of aerogels compare to the density of seawater? a a. The mass of aerogels must be larger. b b. The volume and mass of aerogels must be larger c c. For the same mass, the aerogel must take up less space. d d. For the same volume, the aerogel must have a smaller mass.
I WILL GIVE BRAINLIEST
Answer:
Cleaning up oil spills and metal contaminates in a low-impact, sustainable and inexpensive manner remains a challenge for companies and governments globally.
But a group of researchers at UW–Madison is examining alternative materials that can be modified to absorb oil and chemicals. If further developed, the technology may offer a cheaper and “greener” method to absorb oil and heavy metals from water and other surfaces.
Aerogels, which are highly porous materials and the lightest solids in existence, are already used in a variety of applications, ranging from insulation and aerospace materials to thickening agents in paints. The aerogel prepared in Gong’s lab is made of cellulose nanofibrils (sustainable wood-based materials) and an environmentally friendly polymer. Furthermore, these cellulose-based aerogels are made using an environmentally friendly freeze-drying process without the use of organic solvents.
It’s the combination of this “greener"material and its high performance that got Gong’s attention.
“For this material, one unique property is that it has superior absorbing ability for organic solvents — up to nearly 100 times its own weight,” she says. “It also has strong absorbing ability for metal ions.”
Treating the cellulose-based aerogel with specific types of silane after it is made through the freeze-drying process is a key step that gives the aerogel its water-repelling and oil-absorbing properties.

A pitcher throws a softball toward home plate. When the ball hits the catcher’s mitt, its horizontal velocity is 32 meters/second. The softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what’s the force of the impact? Use F = ma, where .
Answer:
To calculate the force of impact F, first lets calculate the acceleration a of the ball:
a=v/t where v is the velocity of the ball and t is time
a=32/0.8=40 m/s²
To get the force F we need the Newtons second law:
F=m*a where m is the mass of the ball and a is the acceleration.
F=m*a= 0.2*40 = 8 N
So the impact force is F= 8 N.

Min was writing about changes in the state of matter for a research paper. Which of these changes might she include as examples of sublimation?
Choose the two statements that apply.
A. Clothing is hung outside on a day when the temperature is below the freezing point of water. The clothes dry, even though they freeze first.
B. An ice cube melts on the floor, then it evaporates.
C. Bromine is a reddish brown, liquid element. In a closed container, a reddish brown gas exists above the surface of the bromine.
D. Dry ice changes directly to carbon dioxide gas
Sublimation is the process by which solids are instantly transformed into gases. The forces of attraction between solids are completely defeated when they absorb enough energy. Solids, such as dry ice, undergo sublimation.
What is sublimation?Similar to melting, freezing, and evaporation, sublimation is a form of phase transition, or change in a state of matter. Without ever entering a liquid phase, a substance transforms from a solid to a gas through sublimation. Typical sublimation examples include dry ice, which is solid CO2,additional elements that cannot be sublimated. A solid-solid combination is separated by sublimation when one of the components sublimes (transforms from solid to gaseous state without producing liquid) following heating, leaving the other non- sublimable components behind.Sublimation is the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase in between. Sublimation is an endothermic phase transition that occurs at temperatures and pressures lower than a chemical's triple point in the phase diagram.To learn more about Sublimation refer to:
