Answer:
The correct answer is - the phenotypic ratio would be 9:3:3:1.
Explanation:
The two traits that are dominant are free earlobe and straight thumb that are denoted by the E and T on their alternative recessive alleles attached lobe and hitchhiker thumbs denoted by the e and t respectively. The heterozygous condition will be EeTt.
The cross between EeTt and EeTt will produce gametes ET, Et, eT, and et by each. The phenotypic ratio of the cross would be 9:3:3:1, which means 9 out of 16 offspring will be dominant in both trait, 3 will be free lobe and hitchhiker thumb, 3 will be straight thumb and attached earlobe, and 1 will be recessive in both traits. For the cross please check the attached image.
Thus, the correct answer is - the phenotypic ratio would be 9:3:3:1.
In absence of oxygen, the respiratory cycle cannot function, which shuts down the Krebs cycle.
For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

Answer:
It would block the generation of action potential in the motor neurons
Explanation:
Tetrodotoxin (TTX) is a toxic compound found in the Pufferfish which could affect the neuronal signalling in the humans.
The tetrodotoxin binds to the sodium channels present in the motor neurons in the soma region of the neuron where the binding of the tetrodotoxin to the sodium channels inhibits the inward flow of the sodium ions. The reduction in the influx of sodium ions does not change the depolarization of the cell membrane and hence action potential is not generated in the motor neuron.
Thus, It would block the generation of the action potential in the motor neurons is the correct answer.
