Anaerobic process means that process which doesn't require oxygen . Glycolysis can occur in the absence of oxygen and that is why it is an anerobic process. It also takes place in oresence of oxygen, called aerobic process.
The correct answer A.eukaryotic cells ,prokaryotic cells. This means the blood cells are eukaryotic and the bacteria are prokaryotic cells.
The red blood cell although lacks nucleus still is considered to be eukaryotic in nature. The stem cell from where the red blood cell originates has a nucleus which disappears on maturity to make space available for carrying oxygen and carbon dioxide .
The bacterial cells are prokaryotic in nature. The bacterial cell is also enclosed by a cell membrane and the cellular contents are present in the cytoplasm. The bacteria lack the membrane bound structures as opposed by the eukaryotes. nucleus, mitochondria and chloroplast are some of the organelles lacking in the prokaryotic bacteria.
<span>Motility: Mechanical breakdown and mixing of ingested nutrients by smooth muscle movements, passage of nutrients through the digestive tract, and elimination of undigested or unabsorbed residues from the body.</span><span>Secretion: Release of enzymes, hormones, and other substances that take part in digestion.</span><span>Digestion: Chemical reduction of ingested nutrients into particles, then into molecules small enough to cross the lining of the gut and reach the internal environment of the body.</span><span>Absorption: Passage of digested nutrients from the gut lumen into the blood or lymph, which distributes them throughout the body.</span>
