Solution
Growth can best be determined in a population of Spirogyra by measuring the
A
total length of the filament
B
total widths of the filaments
C
rate of photosynthesis in the population
D

A
malleus, incus and stapes
B
malleus, stapes and incus
C
stapes, incus and malleus
D
stapes, malleuls and incus
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
The sequence of ear ossicles, starting from the fenestra ovalis (oval window) and moving towards the eardrum, is: stapes, incus, and then malleus.
Stapes (Stirrup): This is the innermost ossicle, and its footplate sits directly on the oval window.
Incus (Anvil): The incus articulates with the stapes, forming a chain of bones.
Malleus (Hammer): The malleus is the outermost ossicle, and its head articulates with the incus, while its handle is attached to the tympanic membrane (eardrum).
