Which of these is a liming factor with respect to human population size?
A
emigration
B
high standard of living
C
immigration
D
improved medicare
E
natality
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Emigration is considered a limiting factor because it refers to the movement of individuals out of a population, which directly results in a decrease in the population size and density of a specific area. In ecological and demographic terms, factors that reduce population size or growth rate act as "limiters" to the population's expansion in that specific region.

B

C
baldness
D
blindness
E
blood group
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
Sex-linked traits are characteristics determined by genes located on the sex chromosomes (X or Y). While "blindness" is sometimes associated with sex-linkage (specifically color blindness or night blindness), baldness (specifically male-pattern baldness) is frequently cited in biology examinations as a primary example of a sex-linked or sex-influenced trait. In the context of standard educational curricula, baldness is the most distinct example among the provided options for traits influenced by sex-linked inheritance or sex-related factors.
