1. confined aquifers

Explanation:

Artesian well is a type of deep tubular well that is dug underground to collect water for consumption. This type of well is located in confined aquifers.

What distinguishes the artesian well from the others is that it is not necessary to use a pump to make the water rise, as in the case of the cistern. The type of underground reservoir makes the water that passes through the tube spurts on the surface naturally.

The underground reservoir that has the necessary characteristics for drilling an artesian well is the result of very specific geological conditions. The confined aquifer, as this type of deep groundwater is called, results in gushing wells. This type of reservoir is located between impermeable layers of the subsoil.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
