Answer: An indicator is a device or an instrument that is used to measure or record variations pertaining to a solution or substance.

Two good properties of an indicator are as follows-

1) It should be specific- It means that the changes, which are measured by the indicator should be expressed in precise terms so that appropriate assessment could be made.

2) It should be time bound- This means that the measurable changes should arrive withing a particular time limit.

Example of indicator- Litmus is an acid base indicator that turns acidic solutions red and basic solutions into blue color.

(a) What cell structures best reveal evolutionary unity?
xeze [42]

Answer:

The correct answer will be-

1. Evolutionary unity-  DNA

2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.

Explanation:

<u>Case I </u>

Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.

The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.

<u>Case II </u>

The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
