You are called urgently to examine a term, 2-hour-old newborn who has had temperature instability, difficulty with feeding, and a sus- pected seizure. he has atypical facies (wide-set eyes, a prominent nose, and a small mandible), a cleft palate, and a holosystolic murmur. stat laboratory tests and chest radiograph reveal marked hypocalcemia, a boot-shaped heart, and no apparent thymus. which of the following is the most likely diagnosis?

a. ataxia–telangiectasia
b. digeorgesyndrome
c. hyper-ige syndrome
d. scid
e. wiskott-aldrich syndrome

Answer is B. DiGeorge syndrome.

Explanation:

DiGeorge syndrome is a disorder which is caused when part of chromosome 22 is missing. This results in several body systems developing poorly. It is caused when there is abnormal formation of certain issues during fetal development.

One of the symptoms is epileptic seizure.

DiGeorge syndrome is also referred to as the velocardiofacial syndrome.

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.
