2025-2026 complete solution
What |are |three |ways |that |biochemists |study |biological |organisms? |- |ANS |-1. |The |relationship |
between |structure |and |function |of |biomolecules.
2. |The |chemical |reactions |of |organisms |and |or |metabolism.
3. |Communication |with |and |among |organisms.
What |is |the |definition |of |biochemistry? |- |ANS |-Biochemistry |is |referred |to |as |the |'chemistry |of |
life' |as |it |investigates |how |the |properties |of |organisms |relate |to |their |molecules.
What |elements |are |important |to |human |life? |- |ANS |-Bulk |elements |and |trace |elements.
Bulk |elements |consists |of |non-metals |and |trace |elements |consist |of |transition |metals |and |
metals. |
Trace |elements |are |important |in |small |amounts.
What |are |considered |bulk |elements? |- |ANS |-C, |H, |N, |O, |P, |S, |Cl, |Na, |K, |Ca.
What |are |considered |trace |elements? |- |ANS |-Mg, |V, |Cr, |Mn, |Fe, |Co, |Ni, |Cu, |Zn, |Mo, |W, |Se, |I.
, What |is |another |name |for |firefly? |- |ANS |-Lightning |bug |or |glow |worm. |Fireflies |are |also |known
|to |be |beetles.
What |are |the |different |bond |shapes? |- |ANS |-Linear, |Trigonal |planar, |Trigonal |pyramidal, |
Tetrahedral, |Bent.
Linear |- |ANS |-180 |degrees, |sp |hybridization. |
A |straight-line |arrangement |of |atoms.
Trigonal |Planar |- |ANS |-120 |degrees, |sp2 |hybridization. |
A |central |atom |with |three |bonded |groups |in |a |flat, |planar |structure.
Trigonal |Pyramidal |- |ANS |-107.5 |degrees, |sp3 |hybridization.
A |trigonal |pyramidal |shape |occurs |when |a |central |atom |forms |three |bonds |and |has |one |lone |
pair |of |electrons.
Tetrahedral |- |ANS |-109.5 |degrees, |sp3 |hybridization. |
A |central |atom |with |four |single |bonds, |forming |a |3D |tetrahedron.
Bent |- |ANS |-104.5 |degrees, |sp3 |hybridization. |120 |degrees, |sp2 |hybridization. |
