I would answer muscle because muscles are bones that are strong and may break but its nearly inpossible.. ao i think muscles and musclea are the moat important thing because they help you so the stuff you do everyday
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>
Climate change as been the most of the problem
Explanation:
The effect of the position of the CG on the load imposed on an aircraft's wing in flight is significant to climb and cruising performance. ... This requires a higher AOA (Angle of Attack) of the wing, which results in more drag and, in turn, produces a higher stalling speed.
