<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>
Answer:
1. Evolution can be defined as the gradual development of an organism creating diversity.
2. A common misconception is that Homosapiens are descendants of Apes.
3. analogous structures are features of different species that are similar in function, but not necessarily in structure; such as bird wings and insect wings. homologous structures, however, is an organ or bone with similar underlying anatomical features found in different animals; such as the arms of primates.
4. vestigial structures are structures that have no apparent function and appear to be residual parts from a past ancestor, such as wings of flightless birds.
