Question

Can someone please help me with my bio homework #5 and 6 A&B?

5. A red blood cell is 7 m m diameter. How many mm is this? From the reading, what is the size of a human ovum or egg in m? How much smaller than a human ovum is the red blood cell (calculate this by dividing the diameter of In mm? the ovum by the diameter of the red blood cell) 6. If you calibrate your microscope so that 10 reticule units seen through the eyepiece corresponds to 0.06 mm on the slide, then you would be able to measure the size of cells and other structures by just using the ocular lens reticule units. For example, if a cell on the slide was 10 reticule units long, it would be 0.6 mm long. If the cell was 20 reticule units in diameter - how could we figure out its size? We could set up a ratio and a proportion. For example 10 reticule units-20 reticule units , then 10x = 20 x 0.06mm 0.06 mm So: 1 0x 2 and x 1.2 x-0.12 mm 10 Try this with the following: A 10 reticule unis.5 reticule units 0.06 mm 0.06 mm Which of the two above is most likely a eukaryotic cel? How did you decide this? How do we know that 1 reticule unit is equivalent to 0.006 mm? Show the ratio.

Explanation / Answer

5. 1 micrometer = 0.001 millimeters

ANSWER 6

A. (10 ÷ 0.06) = (0.5 ÷ X)

B. (10 ÷ 0.06) = (2.5 ÷ X)

Cell in part A is eukaryotic cell, because eukaryotic cells are larger than prokaryotic cell. And 0.03 mm is larger than 0.015 mm

C. (10 ÷ 0.06) = (1 ÷ X) --- 1 is 1 reticular unit
