In the previous section, you learned that the allele for brown eyes (B) is dominant, and blue (b) and green eyes (g) are recessive, well green eyes are dominant over Blueeyes. What I color would someone with the following genotypes exhibit? (a) BB, (b) Bb, (c) gb, (d) Bg, (e) bb.

(a) BB will have brown eyes

(b) Bb will have brown eyes

(c) gb will have green eyes

(d) Bg will have brown eyes

(e) bb will have blue eyes

Explanation: Allele for brown eyes (B) is dominant, therefore it will manifest outwardly whether is in a homozygous or a heterozygous condition. In this case, BB,Bb and Bg will manifest as brown eyes. Allele for blue eyes (b) and that for green eyes (g) are recessive but (g) is dominant over (b), therefore gb will manifest outwardly as green eyes.

Because (b) is recessive, it must occur in a homozygous state in order to manifest outwardly. This means that (bb) will manifest outwardly as blue eyes.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
