    Female worms are parthogenetic

    Explanation
    Strongyloides stercoralis is a type of parasitic worm that is known to reproduce through parthenogenesis, which means that the female worms are capable of reproducing without the need for fertilization by males. This reproductive strategy allows the female worms to produce offspring without the need for a mate, which can be advantageous in certain environments or situations where males may be scarce or unavailable.

    The larvae are encysted in striated muscles

    Explanation
    Trichinella spiralis is a parasitic worm that causes trichinosis in humans. One of the key characteristics of this parasite is that its larvae are encysted in the striated muscles of the host. This means that the larvae form protective cysts within the muscle tissue, allowing them to survive and develop. This is an important adaptation for the parasite as it enables the larvae to persist in the host for an extended period of time and also facilitates their transmission to new hosts when the infected muscle tissue is consumed.
