Answer: a. runs through the infundibulum
Explanation: The hypothalamus and the pituitary gland (hypophysis) are linked by a structure called the infundibulum. The infundibulum contains vasculature and nerve axons, these nerve axons have endocrine properties.
The hypothalamic-hypophyseal tract runs through this infundibulum
The hopping movement of small grains and sand is called saltation.
During chemical reactions, the bonds that hold molecules together break apart and form new bonds, rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form; without this energy, the reaction cannot take place, and the reactants remain as they were. Simplisticly said During chemical reactions, the chemical bonds between atoms are altered.
