<span>The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. We add therefore the number of protons and number of neutrons </span>

How is the way a dog looks at a face similar to the way humans look at faces
GarryVolchara [31]

Answer:

ever wonder if your dog really really loves you — or if he’s just in it for the kibbles?

Alas, scientists haven’t figured out exactly how our dogs feel about us. But a study published this week in the journal PLOS One has yielded fresh insight into how dogs see us. It adds to existing research showing that — much like humans, other primates and even goats — our canine friends use specific regions of their brain to “process” our faces.

“Our study provides evidence that human faces are truly special for dogs, as it involves particular brain activity,” study co-author Dr. Luis Concha, an associate professor at the National Autonomous University of Mexico’s Institute of Neurobiology, told The Huffington Post in an email. “To dogs, the human face is no ordinary thing.”

The second electron transport chain ends with a(n) ______ that creates NADPH.
mote1985 [20]
1. The right answer is enzymes
NADPH are molecules which are produced during reduction of metabolites (for example glucose metabolism, lipid metabolism...)

2. The right answer is enzymes.
<span>The dark reactions (carbon cycle) act by the reduction of carbon dioxides (CO2) to the level of a carbohydrate (like fructose).
</span>
3. The right answer is ATP.
ATP, or adenosine triphosphate, is a nucleotide of the purine family used to store and transport energy (purines are nitrogenous bases).

4. The right answer is the Calvin cycle.
The Calvin cycle is a series of biochemical reactions that take place in plant chloroplasts. The Calvin cycle makes it possible to manufacture glucose, an energy molecule, from carbon dioxide. This is called carbon fixation.

5. The right answer is NADH
The overall assessment of glycolysis is:Glucose + 2 ADP + 2 Pi + 2 NAD + -----> 2 pyruvate + 2 ATP + 2 H2O + 2 NADH
As we can see, the glycolysis produce indeed 2NADH from a reduction of metabolites during the process.

6. The right answer is Glycolysis.
Glycolysis is the first chain of carbohydrate catabolism, it is carried out in the cytosol by soluble enzymes and anaerobically (without oxygen supply). Its function is the synthesis of a molecule rich in energy, as well as the formation of pyruvate which will have several destinies, including the Krebs cycle.
<span>The Krebs cycle (or tricarboxylic cycle or citric acid cycle) is the energy platform of the cell, continuing the catabolism of carbohydrates after glycolysis. It is realized in the mitochondrial matrix and is done exclusively in aerobic.</span>
