Answer:
C) the group is paraphyletic.
Explanation:
In the classification of hominoids, the orangutan, gorilla, and chimpanzee are grouped together into the Pongidae family; while humans are placed in another family (Hominidae) because this classification recognizes to Pongidae as a paraphyletic group. The paraphyletic groups are the taxa that have a common ancestor and include some (instead of everyone) their descendants. In this case, the Pongidae family is composed of genera that descended from one ancestral species but does not include the complete list of the descendants of that species.
Answer: Gram staining is arranged in the following order;
1) Crystal violet
2) iodine
3) Alcohol-acetone
4) safranin
Explanation:
Applying primary stain to a heat fixed smear of a bacterial culture
Then you add iodine which binds the crystal violet and traps it in the cell. After you decolourise with ethanol finally counter shade with safranin
The data you will collect is the blood phenotype.By adding serums that each contains a particular antibody such as anti-A, anti-B, or anti-D ... to see if there's an agglutination with erythrocytes' antigen and the antibodies, proving the presence of the appropriate antigen in the blood.
This will help to confirm the blood grouping if this technique is done in parallel with the plasma test ( of Simonin-Michon).
