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.

1.

A. Pass Laws

B. Organize Seminars

C. Create a Tax collection program

2.

A. Recycling and waste disposal

B. Poaching

C. Deforestation

<u>Correct Option:</u>

<u>Organize seminars</u> to educate other students about the deteriorating environmental conditions and the steps needed to improve the area. Also, encourage other students to volunteer for workshops about <u>deforestation</u>.

<u>Option:</u> B and C respectively.

<u>Explanation:</u>

As the environmental conditions are deteriorating day by day, thus it is necessary to train to boost upcoming generation for preserving it in most appropriate manner. For such actions awareness is necessary which should be encouraged by some volunteers of non-profit organization, environment protecting units of state and central, etc to conduct seminar in colleges and schools for students to make them understand the need of plantation and disadvantages of deforestation. The pattern to aware them should be remarkable, in order to create huge impact on the new generations towards green land.
