This organism spends its day attached a hard underwater surface. Water currents flowing through it provide the organism with food and oxygen and remove its wastes. It has no organs, but some of its cells have specialized jobs

The correct answer is - Domain monera and archaea.

Explanation:

Archaea and monera is the domain of the organism that include organism with single cell organism that present in extreme atmosphere such as hot springs, and saline water or low oxygen water. The nutrition can be attain by the archaea by the different mode such as sulfur or ammonia and other inorganic matter.

It is an organism that belongs to single cell organism group, however some of the organism have cells with specialized jobs for cells.

Thus, the correct answer is - Domain monera and archaea.

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.
