Ascientist is observing a worm that was found inside a host. the worm that's an outer body that is smooth and soft. which worm is the scientist least likely to be observing. an earthworm, a pinworm, a hookworm or a tapeworm

The answer is the earthworm

Explanation:

Since the scientist is observing a worm that was found inside a host, and worms are not parasites, nor do they need a host to live. On the contrary, earthworms require living in a moist soil that has organic matter. Earthworms starting the organic particles found in the earth that swallows and then expels them forming a pile of excrement. Earthworms are hermaphroditic, and lay their eggs in moist soil.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
