Answer:

7.

Explanation:

pH may be defined as the negative logarithms of hydrogen ion concentration. The pH scale is used to determine the acidity and the basicity of the proteins on the pH scale.

Acids has the pH less than 7 whereas the base has the pH more than 7. Since, the cell contains large amount of water, its pH is 7. Water is a neutral molecule and neutral substances has pH nearly equal to 7 when measured on the pH scale.

Thus, the correct answer is option (A).

Ecological pyramids are graphical representations of the trophic structure of an ecosystem. Regarding these pyramids, check the incorrect alternative.

A) A pyramid is called a number pyramid when it tells you how many individuals there are at each tropic level.

B) The biomass pyramid can be inverted.

C) An energy pyramid can never be reversed.

D) The base of a pyramid is not always represented by the producer. E) A biomass pyramid represents the amount of organic matter found at each tropic level

C. is the wrong option. This is because  it represented the energy fixed in each tropic level . it is never inverted because it flow upwards in the ecosystem.  This energy reduces upwards the pyramid, it is largest at the base of the  producers, and decreases in amount as it flow upwards from one organism at each trophic level to another. This is because each organism uses the energy for biological work
