Asezual reproduction results in greater reproductive success than does sexual reproduction when:
a. pathogens are rapidly diversifying
b. a species has accumulated numerous deleterious mutations
c. there is some potential for rapid overpopulation
d. a species is in stable and favorable environments.

d. a species is in stable and favorable environments.

Explanation:

Asexual reproduction is a mode of reproduction which can be seen in the simple organisms. A single organism give birth to many offsprings. This process does not requires mates and gamete formation. The sexual mode of reproduction involves two parents of opposite sex. This process requires gamete formation. When the gametes of opposite sex fuse together they form a zygote which is a precursor of new offspring.

Asexual reproduction results in greater reproductive success than sexual reproduction as this process does not require mates to give birth to the offsprings. But the asexually reproducing organisms requires stable and favorable environments for production of large number of offsprings. If the external environmental conditions are unfavorable the organism will not survive and reproduce. Thus the reproductive success will decline.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
