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.

Describe the processes that turn metamorphic rock into igneous rock and the energy that powers the processes.
TiliK225 [7]

So, we know that a metamorphic rock is either an igneous or a sedimentary rock that are exposed to intense heat and pressure.

But when the metamorphic rock is thrusted deep underground through subduction, it will again be subjected to intense heat. This can cause it to melt, turning it into a magma. When the magma cools down, it again becomes an igneous rock and the rock cycle continues.
