According to the State University of New York, a fetal pig has a total of seven lung lobes. The right lung is larger and is divided into four lobes<span>: the apical, cardiac, diaphragmatic and intermediate. The left lung has </span>three lobes<span> because it does not have an intermediate lobe.</span>
I believe the positive control receives a treatment with a known response, so that this positive response can be compared to the unknown response of the treatment. This is used in electrophoresis to compare the DNA strands to the DNA standard. The negative control is used when no response is expected, which is also used in the process of electrophoresis. Electrophoresis is a technique used in laboratories in order to separate macromolecules based on size. It applies a negative charge so proteins move towards a positive charge. It is sued for the analysis of both DNA and RNA.
<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.
