Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
The Brodmann areas are a method of mapping the cortex and its distinct functions that was developed by Korbinian Brodmann, after whom the areas are named.
Korbinian Brodmann (November 17, 1868 – August 22, 1918) was a German neurologist best known for classifying the cerebral cortex into 52 distinct regions based on cytoarchitectonic (histological) characteristics. These areas are now commonly known as Brodmann areas.
The Brodmann classification divides the cortex into approximately 52 sequentially numbered areas, though some regions have since been subdivided and others are only found in non-human primates.
It is in charge of motor movements such as contralateral finger/hand/wrist or orofacial movements, learned motor sequences, breathing control, and voluntary blinking. The primary visual cortex (Brodmann area 17) is located on the medial surface of the occipital lobe, in and on either side of the calcarine sulcus.

The answer is D.) the process where distribution of molecules is balanced out by their movement.
Answer:
a) hypothalamus
Explanation:
Within the hypothalamus are nerve cells that, when activated, produce the sensation of hunger.
