All of these are the components of the catabolic pathway or using the nutrients to provide energy from it. The breakdown of food molecules begins in the mouth and continues to the small intestine. The nutrients are absorbed through the wall of the small intestine which. The surface of the intestine wall is specially modified (contains a huge number of hair-like structures-microvilli) which increase nutrient absorption. (more area for nutrients to be absorbed). The digestive tract is lined with mucosa which consists of simple columnar epithelial cells. Monomer subunits of the food, like glucose are than absorbed and diffused down a concentration gradient into capillary blood. Glucose is converted into pyruvate molecules through the process of glycolysis. Catabolism ends in the major energy-converting organelle, the mitochondrion, where the ATP is produced.
Answer:
NAD is reduced
Explanation:
Glycolysis is the first step in the breakdown of glucose in order to generate energy for cellular metabolism. Glycolysis helps to convert glucose into pyruvate and hydrogen ion.
In redox reaction, oxidation is the removal of hydrogen and reduction is the addition of oxygen. In the process of glycolysis, the NAD is reduced to form NADH and H.
If NAD is not present, glycolysis will not be able to continue. During aerobic respiration, the NADH formed in glycolysis will be oxidized to reform NAD+ for use in glycolysis again.
Everything explodes without it. One sentence :)

Answer:
The correct answer is option b. "Alpha eventually replaced by theta".
Explanation:
Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves. Theta waves are the dominant waves during sleeping, and also could be seen during deep meditation.
Answer:
Adult sponges are sessile. This means they are unable to move from place to place.
