Answer:
The answer is letter c, The structure of individual neurons.
Explanation:
Brain-imaging technique- <u><em>this comprises of different techniques for analyzing the brain's activities as well as structure, function and other problems.</em></u>
There are many brain-imaging techniques such as <u>Positron Emission Tomography or PET,</u> which traces the part of the brain that is activated during specific tasks as well as the localization of brain activity in response to a specific stimulus. These areas are seen with high radioactivity.
Patterns of blood flow in the brain can be detected by using <u>MRI (Magnetic Resonance Imaging) test.</u> There is an increase in blood flow to areas in the brain with high activity level.
With the explanation given, it shows that letter c is the only choice that the brain-imaging techniques cannot determine.
In the following orbital the lone pair on each N atom is present:
N1: sp3,
N2: p,
N3: p,
N4: sp2,
N5: sp2
Sitagliptin is an anti-diabetic drug used to treat type 2 diabetes and is marketed under the brand names Januvia and others. One carbon atom has no pi bonds, while the first nitrogen atom is linked to two hydrogen atoms. It thus possesses sp3 hybridization.
The second nitrogen atom possesses a single pair of electrons and is bound to three other atoms. It is hence sp2 hybridized. The nitrogen atoms in positions 3, 4, and 5 have sp2 hybridization.
The lone pair of nitrogen in the first nitrogen atom is in the sp3 orbital. The second and third nitrogen atoms' only pair of electrons are in p-orbitals. The fourth and fifth nitrogen atoms' lone pair of electrons are in sp2 orbitals.

Answer:
The correct answer is C.
Explanation:
The respiratory center is divided into 3 main groups, the dorsal respiratory group and the ventral respiratory group, both located in the <u>medulla</u>, and the pontine respiratory group, located in the <u>pons</u>. This last one also divides into two areas: <em>the pneumotaxic and the apneustic center.</em>
During quiet, restful breathing, the dorsal group stimulates the diaphragm and the intercostal muscles for inspiration. Expiration then occurs depending on the elastic recoil of the lungs. When forced expiration is required, the ventral group activates.
