How human being develop into a organism according to the level of organization​

Higher level of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.

Hydrogen Bromide

Explanation:

Hydrogen is H and Bromine is Br

(C)

In HF, Hydrogen(2.1) and Flourine(3.9) have large difference in electronegativities.

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electron towards itself.

More electronegativity for Flourine, thus, means it pull shared electron pair more towards itself than Hydrogen does. This causes Flourine to acquire partial negative charge and hydrogen to devolop partial positive charge. This results in a polar covalent bond.
