The potato crop devastation occurred in Ireland for not using one single potato species.

Explanation:

Potato became the staple crop of 18th Century Ireland and was easy to grow in the soil of this place.  Later, it became the most dependent crop of the people of Ireland which made its supply very demanding leading to the yielding of more than one species of potatoes.

This yielding reduced the variety in the genetics of potatoes that helped in preventing the disease that affect potatoes by making the Irish people susceptible to famine. The Phytopthora bacteria affected the potatoes of North America in the year 1840 and Ireland’s moist weather in that same year made the blight to thrive.

CaHeK987 [17]

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.
