This happened because the tall plant genotype is dominant, so if the plant has at least one tall gene, it will be tall. All the F1 generation are heterozygous with this tall dominant gene.
        
             
        
        
        
Answer:
Option (C).
Explanation:
Oxidative phosphorylation may be defined as the process of the production of ATP molecule by the use of enzyme and transfer of electrons from one complex to the other complex.
The liver cells has five times large surface area of inner mitochondrial membrane than the outer membrane. This increases the surface area of the inner mitochondrial membrane that increase the rate of the oxidative phosphorylation. The complexes of the electron transport chain is located in the inner mitochondrial membrane.
Thus, the correct answer is option (C).

Answer:
Although more offsprings are produced by the process of external fertilization but the process of internal fertilization is more efficient as compared to external fertilization. This is because, in external fertilization, it is more difficult for the sperm to find the egg and fertilize it. Even after fertilization, it might be that the zygote gets eaten up by a predator. There are none such risks in internal fertilization. The zygote is protected during the internal fertilization which makes this process more efficient.
