Aclient with a diagnosis of pernicious anemia comes to the clinic and reports numbness and tingling in the arms and legs. what do these symptoms indicate?
a) loss of vibratory and position sensesb) neurologic involvementc) severity of the diseased) insufficient intake of dietary nutrients

The correct answer is option B) "Neurologic involvement".

Explanation:

The disease of pernicious anemia could elicit neurologic symptoms that comes from a patient that suffered myelin degeneration and loss of nerve fibers. The neurologic symptoms include numbness and tingling in the arms and legs as well as paresthesias, weakness, clumsiness, and an unsteady gait. When a patient suffers with any of these symptoms is considered that she or he has pernicious anemia with a neurologic involvement.

the answer is d.) homologous; have mammary glands

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.
