Correct answer: Hippocampal

Brain imaging, structural or functional helps us to study the structure and functions of the brain and other parts of the nervous system. Post Traumatic Stress Disorder affects a network of brain areas, like hippocampus, amygdala, cingulate, and prefrontal cortex. In PTSD, the concentrations of corticotropin- releasing factors increases in the cerebrospinal fluids. This stress also leads to the change in the volume and functions of hippocampus, which has a crucial role in memory.

1. Define diffusion.
anygoal [31]

Answer:

1) Diffusion is net movement of anything (e.g., atom, ions, molecules) from a region of higher concentration to a region of lower concentration.

2) Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides

3) One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

4)  Molecules tend to move from areas of higher concentration to areas of lower concentration.

I'm sorry, but I don't know how to do part #2. I think it's a lab.

B does not fit in the situation. It’s not as descriptive as the other options and the only one that really doesn’t make a lot of sense

The particles that make up matter do not change during a(n)?
makkiz [27]
The particles that make up matter are the atoms.

Atoms do not change during a chemical change. They do not either during a physical change.

During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.

For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.

The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.

Why are nonvascular plants short and small? They cannot adapt to decreased sunlight. They lack tubes for transport and support.
Karolina [17]

Non vascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances. ... Non vascular plants are small, simple plants without a vascular system. They do not have a phloem or xylem.
