12. Which of the following will you use to have a clearer image
of individual bacteria strands?
A. Low Power Objective
B. High Power Objective
C. Oil immersion Objective
D. Any of the above
Ans: C. Oil immersion Objective
- By placing a substance such as immersion oil with a refractive
index equal to that of the glass slide in the space filled with air, more light
is directed through the objective and a clearer image is observed. Immersion
oil is best for viewing samples that are dead or not moving protists can
occasionally be viewed with immersion oil, but the best specimes for oil
immersion do not move. Oil immersion is
required when viewing individual bacteria strands or details of striations in
skeletal muscle.
13. What are the correct steps in making a wet mount?

Ans: D. III-I-IV-II
- In a wet mount the specimen on a microscope slide is to get
better view of the spicemen is placed in a drop of water or other liquid held
between the slides and the cover slip by surface tension. The water improves
the image quality and also supports the specimen. The correct way of doing it
is choice D.
14. What is the first step in staining a specimen on a microscope
slide?
A. Adding chemical fixative
B. Applying an appropriate stain
C. Treating the sample with a surfactant
D. Mounting the sample on a microscope slide
Ans: C. Treating the sample with a surfactant
- The main purpose of staining a specimen on a microscopic slide
is to get a better view. Of specimen. The stain usually colors one part of the
specimen, but not another part. By creating that color contrast it becomes
easier to view parts of the subject. The first step is permeabilization, which
is when the sample is treated with a surfactant. This chemical breaks down cell
walls and allows in larger molecules of dye.
The next step is fixation where a chemical fixative is added which will
create chemical bonds between proteins and enhance their rigidity. The samples
must then be mounted on a microscope slide, the samples may be grown directly
on the slide. The last step is applying an appropriate stain which color cells,
tissues and components.
15. Which method of microscope sample placing is appropriate if
the sample is pollen?
A. Dry Mount
B. Wet mount
C. Smear Slides
D. Squash Slides
Ans: A. Dry Mount
- Dry mount require a blank microscope slide, a glass cover slip
and a noun moisture based specimen. Examples of dry mount slides include
insects legs, flower petals, power or substances such as grains of sand or dry chemical, dirt samples and
even newsprint. Wet mount slides are used to view liquids under the microscope.
Wet mount slide samples might include pond water, cheek cells blood or sperm
sample. The purpose of making a smear is to fix the bacteria onto the slide and
to prevent the sample from being lost during a staining procedure. Squash
sliding is used for soft samples.
16. Which may be a replacement for burette when used for
titration?
A. Disposable syringe
B. Eppendorf cup
C. Plastic spot plate
D. Snap-lid glass
Ans: Medical disposable syring may be used as a replacement for
pipettes and burettes in a microscale titration. The disposable syringe has a
transparent cylinder with well read graduation, which is smudge-proof. When
using disposable syringes as burette replacements, liquids must be filled in
the syringe without any air bubbles. For this purpose first some liquid is
taken up with syringe and then abruptly forced out again. If this process is
repeated several times, the bubble-free filling of the syringe can be managed.
Slow charging and discharging is possible with these syringes.
17. Which of the following can serve as alternative for petri
dishes and spot plates?
I. Tin can
II. Plastic
III. Empty pill package
IV. Container of cosmetic product
A. I only
B. I and II only
C. I, II and III only
D. I, II, III and IV
Ans: D. I, II, III and IV
- Empty package material which produce in many households as waste
products, can also be used as rection chambers for chemical and physical
experimental. For instance the use of empty pill package, glass, tin, plastic
cups, or containers of cosmetic products are very well suited. These empty pill
package also have the same benefits as the multiwellplates. Once the aluminum
foil is removed from the drug package all the expirements, which can be
conducted in spot plates, can also be conducted in a empty pill package. If
larger capacity than the capacity than the capacity provide by the empty
provided by the empty drug package is required, glass (e.g cleaned jam or honey
jar ), or plastic cups can alternatively be usd as reaction vessels.
18. Plants are classified as herbs, shrubs and trees. What
is the basis in this biological classification?
A. Evolutionary relationship
B. Gene pool
C. Morphology
D. Phylogenetics
Ans: C. Morphology
-Morphology forms the primary basis for classifying
organism into various taxonomic groups of taxa. It deals with the structure or
the physical appearance of the organisms. The similarities in the morphological
characters are used for grouping the plants together as herbs, shrubs, vines
and trees. Phylogenetics is the study of evolutionary relationship among the
species.
19. Which of the following statements is TRUE?
A. Prokaryotic cells came before Eukaryotes cells
B. Prokaryotic cells are bigger than Eukaryotic cells
C. Eukaryotic cells are simple, Prokaryotic cells are complex
D. Eukaryotic cells do not have nucleus, prokaryotic cells do.
Ans: A. Prokaryotic cells came before Eukaryotes cells
- Prokaryotic cells are often thought to be the first life on the
planet. Evidence supports the idea that eukaryotes cells are actually the
descendants of separate prokaryotic cells that joined together in a symbolic.
20 In a laboratory experiment design to demonstrate one aspect of
photosynthesis, three test tubes were treated as shown above. The test tubes
were then placed under a bright lamp for 24 hours. Which of the following is
the best explanation for the observed color change in tube 2?
A. The aquatic plant used carbon dioxide, raising the pH of the
solution
B. The light bleached the solution from its original color of
yellow to blue
C. The light plant produce oxygen during photosynthesis which
caused the color change
D. The aquatic plant produced carbon dioxide, which change into
carbonic acid and caused color change.
Ans: D. The aquatic plant produced carbon dioxide, which change
into carbonic acid and caused color change.
- Bromothyle blue can be used as an indicator of CO₂
concentration. CO₂ dissolves in solution and a small percent becomes carbonic
acid. Plants utilize CO2 during photosynthesis, thus raising the pH of the
solution and changing the color of the solution from yellow to blue.
