PAPER 2026 QUESTIONS WITH ANSWERS
GRADED A+
• How are agar plats inoculated for disk diffusion testing of antiseptics and
disinfectants....
Answer: a swab is used to inoculate the entire surface of the plate, producing
a lawn of growth
• Satellite viruses are....
Answer: dependent of other viruses for replication
• Flagella.
Answer: -help locomotion -flexible -made of microtubules in 9+2 fashion
• Key scientists of spontaneous generation.
Answer: Francesco Redi, John Needham, Lazzaro Spallanzani
• Photosynthetic Membrane Structures.
Answer: -Cyanobacteria and photosynthetic bacteria have specialized
structures to perform photosynthesis - Infoldings of the plasma membrane
encloses photosynthetic pigments (e.g. chlorophyll)
• In general, most DNA viruses multiply in the host cell's __ while most RNA
viruses multiply in the host cell's __ ....
Answer: nucleus, cytoplasm
• microscope types.
Answer: 1.light microscope 2.electron microscope 3.scanning probe
microscope
• Which of the following is not a polymer....
Answer: glucose
• cell wall.
Answer: found in eukaryotes & prokaryotes, Found outside the cell
, membrane, Aids in protection against osmotic pressure changes
• All of the following are helminths except....
Answer: trypanosomes
• Steps of Flagella Staining.
Answer: 1.No heat smear 2.Primary stain (specialized) 3.Decolorizer (water)
4.Counter stain (carbol fuschin)
• A drug exhibiting which therapeutic index value would be the safest, most
effective to use on a patient....
Answer: 20
• path of light.
Answer: CondenserIlluminator (light source)-->Specimen-->Objective
lens-->Ocular lens
• differential interference contrast "Nomarski" microscope.
Answer: similar to the phase contrast, two beams of light are created in
which the direction of wave movement (polarization) differs, this results in
high-contrast images of living organisms with a three-dimensional
appearance.
• Which of the following is not a polymer....
Answer: glucose

Answer: Barbara McClintock
• Chitin is a chemical component of the cell walls of....
Answer: fungi
• intermediate filaments.
Answer: -anchor nucleus and other organelles -form nuclear lamina
• John Needham.
Answer: Believed there was a life force that caused spontaneous generation
• cell wall in myobacteria.
