Hello!! Your answer would be C - Medulla oblongata. The medullary respiratory center includes two groups of neurons that extend throughout the length of the medulla oblongata. They are called the ventral respiratory group and the dorsal respiratory group. The ventral respiratory group is responsible for regulating inspiration and expiration. The dorsal respiratory group stimulates the inspiratory muscles, like the diaphragm (near bottom of ribs). It also helps process sensory information related to the respiratory system. Neurons in the brainstem are a part of the pontine respiratory group which limits inspiration and help the rhythm of breathing. I hope I helped give you a better understanding. Have a great evening!!

This branch of biomechanics that is being referred above is called NANOBIOMECHANICS or BIONANOMECHANICS. This branch of study focuses on the understanding of how cell materials interact within the body and one of these is how diseased or defective blood cells react to forces. Mostly, nanobiomechanics cover biomechanics problems or diseases.
I believe the best way to explain is that three times as many tall plants as short plants. The parental generation is the first set of parents crossed, the F1 generation consists of all the offspring from the parents, while the F2 generation consists of the offspring from allowing the F1 individuals to interbreed. From the Mendel's experiment the F2 generation results from self-pollination of F1 plants, and contained 75% of tall plants and 25% of short plants.
