  • To view the haemocoel, you would pick Scolopendra

    Haemocoel is present in Centipede, as it belongs to Phylum Arthropoda. Hence, the correct answer is option (C). Note: Haemocoel is a body cavity present in the animals belonging to Phylum Arthropoda and Phylum Mollusca. Centipede shows haemocoel as it is an arthropod.

  • The growth in arthropods goes along with Ecdysis And Molting

    In order to cope with this situation, arthropods undergo a process of shedding their exoskeleton and forming a new one periodically throughout their lifetime. This process, shown in Figure below, is called molting, or ecdysis, and is regulated by special hormones that coordinate molting events with stages of growth.

  • The electric current is produced when electron move from one position to another position.

    The mobility of electrons decide the magnitude of electric current and the number of electrons will decide the resistivity.

    The charge of electrons is correlated to electric current.

    The electric current will be produced in the direction of opposite to the flow of electrons.
    The drift current is produced in the circuit in the direction of movement of electrons.
