Answer:
The correct answer is - *It relates directly to the characteristics of the plant's environment*
Explanation:
The relationship between structure and function can be represented by the leaf structure as the structure of a particular plant leaf gives an idea about the characteristics of the environment it is habituated.
In the dry area or deserted area, leaves are modified into spikes to save water in order to lower transpiration, number of waxy coating, number of chlorophyll, and other modifications that give an idea about the environment and light intensity, and other characteristics.
Answer:
All the offspring from parthenogenesis are female. So if the female stick insects carry on reproducing alone, the males could be wiped out. ... This may help explain why parthenogenesis remains rare, even in species that are capable of it. In such species, "males typically force females to mate".

Carbon skeletons may vary in length, shape, number and location of double bonds and other elements covalently bonded to available sites.
A carbon atom contains four valence electrons thus, exhibiting a strong tendency to make covalent bonds with other atoms so as to complete its octet. Covalent bonds join carbon atoms together in long chains that create the skeletal framework for organic molecules.
A carbon atom could be linked to as many as four additional carbon atoms in an organic compound. Carbon atoms can also quickly form double bonds (where four electrons are shared among two atoms) and triple bonds (where six electrons are shared).
This variation in carbon skeletons contributes to the diversity and complexity of organic molecules.
