Aheterozygous male and a homozygous female plants are cross-pollinated. what is the genotypic ratio of the offspring

When a heterozygous male and homozygous female plants are cross-pollinated the genotypic ratio of the offspring will be tt, Tt

Explanation:

In a pea plant, when the heterozygous male plant (Tt) is cross-pollinated with homozygous female plant (tt) ;

T × t = Tt

t × t = tt

t × T = tT

t × t = tt

Therefore, the genotypic ratio of the offspring is short and tall (tt, Tt) because the dominance of tall trait is less that the short trait, indeed the chances of tall offspring is low.

a- all cells come from pre-existing cells

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.
