Answer 1

binary fission:

in this process the parent cell divides to form two daughter cells

it occurs under favourable conditions

there is no cyst formation.

multiple fission:

in this process the parent cell divides within the cyst to form many daughter cells

it occurs under adverse conditions

the organism forms a protective layer around itself called as cyst.

during zygote formation, man contributes either x or y chromosomes to the next generation.

but female transfers only x chromosomes to the offspring.

at the time of fertilization, if x chromosome come from male then it is a girl and if y chromosome then it will be a boy

thus the gender or sex is determined by the male partner
