Of what is this an example? a child with a widow's peak has a mother who is homozygous dominant for a widow's peak and a father who is homozygous dominant for a widow's peak.

a, heterozygous

b, homozygous dominant

c, homozygous recessive

d, heterozygous recessive

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

hope this .

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
