Antibiotics have a tendency to weaken the immune system.
Answer:
English:
RNA and DNA are polymers made up of long chains of nucleotides . A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
Spanish:
El ARN y el ADN son polímeros formados por largas cadenas de nucleótidos. Un nucleótido está formado por una molécula de azúcar (ribosa en el ARN o desoxirribosa en el ADN) unido a un grupo fosfato y una base nitrogenada. Las bases utilizadas en el ADN son la adenina (A), citosina (C), guanina (G) y timina (T).
C. The digestive system breaks down food and the circulatory system transports the nutrients throughout the body.
The Digestive system is the system that helps the body digest food. It consists of the following organs: liver, stomach, gallbladder, large and small intestines, pancreas, rectum, and esophagus.
The Circulary system is the system that pumps blood through body. The blood contains all the nutrients and minerals the body needs. The system consists of the following organs: heart, blood vessels, blood, lymph, lymphatic vessels, and glands.
The correct answer is: Endoplasmic reticulum.
One of the functions of the endoplasmic reticulum is transport of secretory proteins. Synthesized proteins are transported in vesicles to the Golgi apparatus.
Gastric chief cells have a high rate of enzyme secretion such as pepsinogen and gastric lipase. It is the cell also responsible for secretion of chymosin.
