Clean coal is meant to drastically improve emissions, but no matter how much you treat it, it still creates an environmental impact
The correct answer is this: ZEITOUN SPOT FISH SWIMMING IN THE FLOOD WATER.
The passage given above was drawn from an account of Hurricane Katrina by Dave Eggers. In the passage, he described the hurricane experience as an apolycapses, thus likening the event to the great destruction that will befall the earth at the end of the world as recorded in the bible in the book of Revelation. The hurricane was so bad that those animals that can not fly were carried away in the flood, even the fish inside the water were affected.
Answer:
What is the effect of power/magnification on the frequency and size of organelles under a microscope?
Explanation:
Organelles within the cell are responsible for carrying out various functions. Some cells are more specialized than others, and may have particular organelles at a higher frequency, or showing a variation in size; sub-cellular structures become more visible at higher magnifications under the microscope.
Hypotheses:
- organelle A's frequency decreases while B's frequency increases at higher magnifications
- organelle A's size increases while B's size decreases at higher magnifications
<em />
<em>Dependent variables: size and frequency cell organelles</em>
<em>Independent variable: power/magnification at low (x4), medium(x10) and high (x40)</em>
<em>Controlled variables: Type of organelles, microscope used, cell examined, </em>
Method:
1. Examine the organelles A and B in a cell mounted on a slide; use the fine adjustment to focus on the cell.
- Frequency: What is the average number of organelle A versus B, seen at low (x4), medium (x10) and high (x40) magnifications?
- Size: Measure the average diameter of organelle A versus B using an ocular micrometer at low, medium and high magnification.
2. Record and tabulate observations.
(1) A. (2) D. (3) B. (4) A. (5) B. (6) C. (7) B. (8) B. (9) B. (10) A.
A. Catabolic because it brings substances together
