Answer:
Explanation:
1)Glucose is a simple sugar which can be readily absorbed by the body. Once inside, glucose undergoes oxidation, which results in the release of ATP, a high-energy molecule that provides energy for the cell.
2)Similarity: Both Amoeba and human beings are heterotrophs and derive nutrition from other organisms.Similarity: Both Amoeba and human beings are heterotrophs and derive nutrition from other organisms.
Difference-Human beings have a complex digestive system and different nutrients are digested in separate regions. Amoeba does not have a digestive system and all the nutrients are digested in the food vacuole.
3)Humans cannot survive only on raw, leafy vegetables, or grass. It is because the grass is rich in cellulose, which is a type of carbohydrate that humans are not able to digest due to the absence of cellulose-digesting enzymes. ... So human cannot survive only on raw, leafy vegetables.
4)Absorption: The process of absorbing food in the form of nutrients into the blood stream of the body.
Assimilation: The process of nutrients being absorbed by each cell of the body in the form of energy.
5)Rumination-Regurgitating food after a meal and then swallowing and digesting some of it. Cattle and other ruminant animals have a four-chambered stomach for the rumination of food and so can chew their cud.
6)The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
7)Ingestion is the process of taking in the food into the body either by swallowing or absorbing it. Amoeba pushes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. This process is known as phagocytosis
8)ingestion - the intake of food into the body
egestion - the elimination of wastes out of the body.
digestion-The elimination of wastes of the digestion occurs through the anus in animals.
9)Incisors are the teeth that you use to bite into your food. Canines - Your canines are the next teeth that develop in your mouth. You have four of them and they are your sharpest teeth, used for tearing apart food.
10)Solid foods aren't as nutritious as breast milk or formula, which are essential for proper growth and brain development in young infants. Solid foods are harder to swallow. A baby may not be developed enough to swallow solid food properly before the 6 months.
