An aquifer is actually an underground layer of water that contains permeable rocks, gravel, sand etc. the water can be brought to the surface by making a water well. Hydrogeology is the study of aquifers and the way of water flow in the aquifers. The depth of the aquifers differs from area to area and the aquifers that are closest to the surface are used for drinking and irrigation purposes. </span>
Answer: The correct answer is as follows:
Stage 1) Egg - Frogs begin their life as fertilized eggs. A typical female frog can lay thousands of eggs, depending on the species. In the pond, the eggs float on the water in clusters until they hatch in 2-3 weeks.
Stage 2) Larva (tadpole) - During the tadpole stage, the frogs eat, grow and develop into froglets (with four legs) through a process called metamorphosis. As tadpoles, they rely on rudimentary gills, mouths, and tails for swimming. The tadpole's diet includes other frog eggs, bugs, mosquito larvae, and other dead insects. As their four legs and external respiration develops, the froglet is almost ready to leave the water.
Stage 3) Adult - At around 12 weeks of age, the frog has reached maturity as an adult and is ready to explore dry land. With its gills and tail totally absorbed back into the body, the frog remains an amphibian but spends most of its time out of the water. As an adult, the frog uses its sticky tongue to capture and eat insects, snails, slugs, and worms. They return to the water to lay new eggs and the cycle of life repeats.
Explanation:
I would say the first one
Supercooling and Superheating. "superheating". Generally speaking, a substance undergoes a "phase change" from liquid state to gaseous state when it is heated to its boiling point.
"Supercooling" is the process of chilling a liquid below its freezing point, without it becoming solid.
B. Hold large amounts of food.
Some parts of plant materials, like cellulose, are hard to digest. The digestive tract of herbivores is adapted so that the food can be digested properly.
