Answer:

D.

Explanation:

If it is just a physical change then we can instantly cross out B. and A. as they say in there that they become a new substance and that is not just a physical change. C. is not correct because they combine and there for make a new substance. That leaves D. which makes sense because a physical change would be a change in its size or something that doesn't change the material, this is like when you break a rock, it is now in pieces and smaller but it is still the same rock therefor it is a physical change.

Define the following terms in regards to the brain: ventricles, hemispheres, gyri, sulci, fissures, lobes, cerebral cortex.
Ymorist [56]

Answer:

ventricules.-The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle.

Hemispheres.-The left side of the brain is responsible for controlling the right side of the body. It also performs tasks that have to do with logic, such as in science and mathematics. On the other hand, the right hemisphere coordinates the left side of the body, and performs tasks that have do with creativity and the arts.

Gyri and Sulci.- Sulci, the grooves, and gyri, the folds or ridges, make up the folded surface of the cerebral cortex.  A sulcus is a shallower groove that surrounds a gyrus.

Fissures.- A fissure is a large furrow that divides the brain into lobes and also into the two hemispheres as the longitudinal fissure.

Lobes.- Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.

Cerebral cortex.- the furrowed outer layer of gray matter in the cerebrum of the brain, associated with the higher brain functions, as voluntary movement, coordination of sensory information, learning and memory, and the expression of individuality.
