Answer: Prodomal period or stage.
Explanation: The prodromal period comes after after the incubation period (i.e. stage of entry and multiplication).
During this stage, the pathogen continues to multiply and the host starts to establish general signs and symptoms of illness, which occurs as result of the immune system activation. Signs and symptoms like soreness, pain, fever, swelling, or inflammation, is experienced by the host.
However, these signs and symptoms serves as basic diagnostic tool to determine the particular disease.
Answer:
The instructions for making proteins are coded in the (cytoplasm / <u>DNA</u> / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / <u>nucleus</u>).
Explanation:
The genetic code is contained in DNA, or deoxyribonucleic acid. This is usually the same among most organisms, save some RNA viruses. But in eukaryotes, the DNA is in the nucleus, whereas in prokaryotes the DNA is in the "nucleoid region", or a twisted up section near the middle of the cell.
