The aquifer which will be most effective in purifying polluted ground water is AN AQUIFER COMPOSED MAINLY OF SAND.
An aquifer refers to a zone of permeable rock strata which transmit ground water freely. An aquifer must be permeable and porous. Ground water can be extracted from an aquifer by using a water well.
Answer:
C. They have a greater surface-to-volume ratio.
Explanation:
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.

If your choices are the following, then the correct answer is C:
a. The aerobic bacteria were able to capture the sunlight and generate sugars from it.
b. The aerobic bacteria helped protect the cell against desiccation.
c. The aerobic bacteria metabolized sugars and generated large amounts of ATP.
d. The aerobic bacteria helped protect the cell against predation.
This is actually the endosymbiotic theory of how we humans (and other organisms alike) have evolved to have mitochondria inside our cells. Evidence to support this is that mitochondria have their own DNA different from ours.
<em>A</em> can't be the answer because that is more related to plants. <em>B and C </em>are also wrong because they simply do not provide those functions.
The correct answer is C. This part is called the epithelium.
It is the muscular coat which consists of inner circular and outer longitudinal smooth muscle. Its main work is peristalsis.
To propel urine. The outer layer is the mucosa which has transitional epithelium that continuos with the lining of the renal pelvis and also the urinary bladder.
This layer of its work is to secrete mucus which protects and coats the surface of the cells.
