Answer:
Explanation:
1. can generate energy – Both , In landfills methane gas is produced which is used to generate electricity, like wise heat energy produced in incinerator is also used for producing energy
2. emits toxins through combustion – Incinerators produce dioxins which is a dangerous chemical
3. drains liquids into the ground – Land fill, leachate is a common issue with all landfill site.
4. releases greenhouse gases – Both, methane and other carbon gases are produced in both landfill and incinerators
5. requires a substantial amount of land – land fill site , needs a large land to dump the city waste
6. generate ash – Incenerator only
Answer
1. The writing utensil’s placement facilitates the drawing of two or more lines with a single stroke of the pantograph. This means while drawing an image two or more copies of varying sizes may be created at the same time. The pantograph mirror is used to extend or retract an image.
2. The operation of a pantograph relates to dilations and similarity in that both of the processes are done on the graph and it is possible to use similar triangles through measuring the size of the triangles. Pantograph contains links that maybe arranged in other ways because they contain a parallelogram.
3. You can use similar triangles to describe the working of the pantograph because the ratio of similitude is set when determining where to put the pin. When one triangle is moved with the part being specific to the point (tracing style), along the outline of the image, an enlarged/reduced version of the image is created by movement of the other triangle (drawing stylus point).
4. Pantograph has been replaced by modern ways of producing duplicates such as photocopying, mass printing and digital filing. This is because the technique is currently outdated and the fact that it is difficult to use then now due to their complex designs which does not allow users to properly grip an actual writing utensil like the pen.
The answer is; concentration of oxygen and/or total atmospheric pressure is lower at high altitudes
This means that at high altitude, due to the low pressure, every breath has a lower oxygen content than at a lower altitude. This, therefore, necessitates the body to increase the erythrocyte numbers in the blood to maximize the uptake of oxygen from the thinner air.
Answer:
B. move by osmosis from solution B to solution A
Explanation:
Remember that osmosis as a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
