Answer: 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.

Answer:
Energy may be transferred from place to place or transformed into different forms,
Explanation:
Energy cannot be created or destroyed
The larger the electronegativity value is, the stronger the attraction of electrons to an atom is. This means that in a covalent bond the atom with the higher electronegativity value will have a slightly negative charge since it pulls the electron(s) towards itself while the other atom gain a slightly positive charge since the electrons move further away from its nucleus.
