What is the name of thespecific organelle that is studded with<br> ribosomes in a eukaryoticcell?
Alik [6]

Answer:

The (rough) endoplasmic reticulum

Explanation:

The endoplasmic reticulum is a system of interconnected membranes that functions in the synthesis of several membrane-related proteins and lipids. There are two types of endoplasmic reticulum in the eukaryotic cell;

  • Smooth endoplasmic reticulum
  • Rough endoplasmic reticulum

The smooth endoplasmic reticulum is actually smooth because it has no ribosome attachment while the rough endoplasmic reticulum appears rough due to the attachment by ribosomes.

<em>Therefore, the name of the specific organelle that is studded with ribosomes in eukaryotic cell is endoplasmic reticulum.</em>

Write characterize progression of infectious disease.
vlada-n [284]

Answer:

* Infectious disease management depends on precise portrayal of disease progression so transmission can be forestalled. Gradually progressing infectious diseases can be hard to characterize because of a latency period between the time an individual is infected and when they show clinical signs of disease.

* Defining directions through sickness states from infection to clinical illness can assist researchers with creating control programs dependent on focusing on individual infection state, possibly decreasing both progression and creating misfortunes because of the illness.

Explanation:

Gradually progressing infectious diseases are hard to characterize in light of the fact that they are frequently connected with an inactivity period between the time an individual is infected and when they give clinical indications or side effects of illness.

To successfully control infectious diseases, it is paramount to see how the disease progresses.
