Answer:
Reproductive isolation
Explanation:
Reproductive isolation is the lack of successful breeding between organisms of related species due to the existence of morphological, physiological, genetic or behavioural barriers.
Reproductive isolation mechanisms are classified into two:
- Pre-zygotic mechanisms, and
- Post-zygotic mechanisms
The pre-zygotic mechanisms act to prevent breeding or formation of zygote between organisms of related species while the post-zygotic mechanisms act to ensure that aborted or infertile zygote results in cases where fertilization takes place.
<em>The distinct characteristics observed in the species of butterfly can be viewed as a form of morphological reproductive isolation.</em>

Answer:
C
Explanation:
First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
