<u>Answer:</u>
The series dilution method is the step wise dilution technique where the dilution factors remain constant in each step.
The advantages of using the series of dilution method over simple dilution are stated below:
<em>a) Aids in reduction of a dense culture of cells to a more usable concentration.</em>
<em>b) In every step of dilution the specific amount of bacteria is removed. </em>
<em>c) Helps in the estimation of concentration of an unknown sample.</em>
<em>This sums up the advantage of using the series dilution technique.</em>

Air is a poor conductor of heat, so the air trapped among the feathers
prevents the loss of heat in cold atmosphere, and prevents overheating

Genetic engineering is applied to techniques like DNA cloning in which the steps are: step 1: DNA cutting from the parent source; step 2: DNA cut is pasted into the matrix to be modified; step 3: matrix is introduced to the host cell and step 4, vector DNA is isolated. Answer then is B.
The correct option is B.
A multi cellular organisms has many cells which carry out various function and which are organised into tissues, organs and organ system. A unicellular organism on the other hand has only one cell with different cell organelles. Thus, in unicellular organisms, it is the cell organelles that carry out different functions. <span />
