The substrate of the citric acid cycle which can block respiration when it is present in excess is MALONATE. Malonate inhibits respiration by competing with succinate dehydrogenase for its acitve site. Malonate binds to the active site without reacting, thus competing with succinate. This disrupts the cellular respiration in the cell.
I’d say conical shape- coniferous trees are known for this shape.
Answer:
BbxBb.
Explanation:
If Bb gene is crossed with Bb, the offspring is produced with normal hearing because both the genes are recessive in which the deafness gene hide and the hearing gene is dominant so the offspring can hear sounds clearly. The dominant A gene is responsible for deafness and we can see the offspring BbxBb in which no dominant gene is present. The other three offspring are deaf because of the presence of dominant A gene in their genetic makeup.
