Answer:
a. 1/2 b. The organism is an animal
Explanation:
a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?
Medullary index = diameter of medulla/diameter of hair.
Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,
Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2
b. Is this organism human or animal?
Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.
<u>Colony morphology on agar</u> is NOT a phenotypic test.
Examples of phenotypic tests are;
- Antibody reaction
- Antibiotic resistance profile
- Gram staining
Explanation:
Colony morphology is the visible shape taken by a colony of microorganisms. Phenotype, on the other hand, is the external traits of an individual organism based on its genotype and environmental influence. Colony morphology is not determined by the genotype of the organisms hence can't be considered a phenotype trait.
