The introduction of foxes in order to control, or even decline, the rapidly growing rabbit population was not effective due to very simple reasons, reproduction rates and available area for living.
The rabbits are reproducing quicker than the foxes, and not just quicker, but in larger numbers with every lither, thus outnumbering the foxes by far, even if each fox manages to kill a rabbit or two each day.
The area available for the rabbits to live and spread out is huge, so they are not limited by a small amount of area where their number will have to stop to grow because of lack of food sources, thus spreading around without any problem, especially because of the lack of competition.

Answer: homo sapiens is the only species with a large enough oral cavity and a low enough larynx to allow for speech production.
<span>One line of evidence that speech only possible for modern homo sapiens is the anatomy of their throat. Speech depends on certain anatomical arrangements and the Homo sapiens is the only species with a large enough oral cavity and a low enough larynx that would allow speech.</span>
The right answer is polarity.
In chemistry, polarity is a characteristic describing the distribution of negative and positive charges in a dipole. The polarity of a bond or a molecule is due to the difference in electronegativity between the chemical elements that compose it, the differences in charge that it induces, and to their distribution in space. The more the charges are distributed asymmetrically, the more a bond or molecule will be polar, and conversely, if the charges are distributed in a completely symmetrical manner, it will be apolar, that is to say non-polar.
Polarity and its consequences (van der Waals forces, hydrogen bonding) affect a number of physical characteristics (surface tension, melting point, boiling point, solubility) or chemical (reactivity).
Many very common molecules are polar, such as sucrose, a common form of sugar. The sugars, in general, have many oxygen-hydrogen bonds (hydroxyl group -OH) and are generally very polar. Water is another example of a polar molecule, which allows polar molecules to be generally soluble in water. Two polar substances are very soluble between them as well as between two apolar molecules thanks to Van der Waals interactions.
It shows the "rank" of the organism is not a characteristic of the cladistics system. Showing the probable sequence of origins, and showing shared derived characteristics are characteristics of the cladistics system.
