Answer;

petit arm

Explanation;

All human chromosomes have 2 arms, the p (short) arm and the q (long) arm. They are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during cell division.

The symbol "p" stands for "petit", small in French, while "q" was chosen merely because it was the next letter in the alphabet.

1. Explain why planarians and flukes are called flatworms.
Marta_Voda [28]

Answer and Explanation:

Platyhelminthes are mostly worm like organisms that are dorsoventrally flattened, meaning they look like a leaf and this is why they are coined names like the Tapeworm, Flatworm, Fluke and Planarian.

Most Platyhelminthes are parasites on other animals but only the Turbellarians are mostly non-parasitic. A few species are commensalists, or mutualists living with other larger organism.

They are classified into:

  • Class Turbellaria
  • Class Monogenea
  • Class Trematoda
  • Class Cestoda
