Answer;
Golgi apparatus or golgi complex.
Golgi complex is the organelle that modifies proteins before they are either used by the cell or transported out of the cell.
Explanation;
Golgi complex is also called golgi apparatus or golgi bodies; is made up of membrane-bound sacs .
Its function is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell. That is; modifying, sorting and packaging of proteins for secretion.
Additionally; it is also involved in the transport of lipids around the cell, and the creation of lysosomes.
Answer:
delaying cell senescence, apoptosis, and death
Explanation:
Peristaltic movement is the constriction and relaxation of longitudinal muscles in the gastrointestinal tract in the esophagus, stomach, and the small intestines. It occurs in a wavelike constriction resulting to a process called peristalsis. In the esophagus the movement helps push food in form of bolus (small rounded mass of food) to it.
Answer:
d. self-replicating RNA molecules
Explanation:
RNA molecules are single stranded, not included double stranded RNA structures from self folding, and DNA molecules are double stranded. It is thus believed that RNA molecules was the original genetic material and eventually DNA evolved from RNA and overtook RNA as the genetic material given DNA enhanced stability. Thus the answer has to be RNA.
