Vagus nerve
Cranial nerves supply sensory and motor information to structures of the head and neck, controlling the activity of this region. Only the vagus nerve extends beyond the neck, to innervate thoracic and abdominal viscera.
Answer:
Out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
Explanation:
As we all know, that rate of diffusion is linked to the surface area--to--volume ratio. Larger surface area--to--volume ratio depicts that the surface area of an object is higher that than of its volume. The higher surface area provides higher area for diffusion.
Thus, any smaller object with larger surface area--to--volume ratio will provide higher diffusion rate and hence the time for diffusion will decrease.
While any object with smaller surface area--to--volume ratio will provide lower diffusion rate and hence the time for diffusion will increase.
Thus, out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
Answer:
In most species of frogs, fertilization is external. The male frog grabs the female's back and fertilizes the eggs as the female frog releases them (Figure 2.2B). ... The egg pronucleus and the sperm pronucleus will meet in the egg cytoplasm to form the diploid zygotic nucleus.
