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.

almond37 [142]

Answer:

B) and D) are the correct answers

Explanation:

Hadalpelagic zone contains life such as amphipods , snailfishes  and cusk-eels.

Epipelagic zone is the ONLY zone where visible light and algae can be found.  Lower than that the amount of light is  insufficient for plants to carry out  photosynthesis.

The mesopelagic zone has a diverse biological community that includes unique organisms adapted to live in a low-light environment including fish like

the blobfish, bristlemouths or the tasselled anglerfish.

Cells that engulf bacteria or cell debris within loose connective tissue are
gulaghasi [49]

Answer:

macrophages

Explanation:

Macrophages are a type of immune cells that function as phagocyte. They are produced by white cells called the monocytes. Upon ingestion of bacterial cells, cytotoxic compounds e.g cytokines are produced that digest the bacteria.

The macrophages are activated by the presence of microbes in the blood. They activate antigen T presenting cells to produce cytokines that further destroy the engulfed bacteria.
