We have that
<span>1 kilometer (km) of length
Equals 3,280.84 feet (ft) in length</span>
If we apply a simple
rule of 3

Answer:
villi is used and is very imp as it has structure like finger type which help for increase in surface area for more absorption and less wastage of water/minerals
The answer is "because water is produced as a by-product"...the word dehydration should also be a major clue because that means water loss.
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.
Answer:
Mollusca Phylum
Gastropoda class
Explanation:
The Mollusca Phylum is one of the most noticeable phyla that includes a wide variety of forms.
The ancestral Mollusca used to habit the pre-cambric oceans. It was bilaterally symmetrical, with a well-defined head that had tentacles and ocellus. Its ventral surface was plane and muscular, shaping a reptant foot. The dorsal surface was protected with a convex and oval shell.
The Gastropoda class is the richest class among all mollusks. This class experienced a characteristic torsion in their shell. This twist also involved the visceral mass, the mantle, and the mantle cavity. But by the time that this torsion occurred, the shell had already experienced a turn into a coil shape, which was then followed by its torsion.
The typical gasteropod´s shell is a conical structure composed of several tubular spirals containing the individual´s visceral mass. The biggest spiral ends as an opening from which the head and the food protrude.
