Answer:
Option 4
Explanation:
Folate is vitamin B and occurs naturally in various food items such as green leafy vegetable, lentils, peas, beans, in fruits such as banana, melon, and enriched products such as bread, juices etc. Folate is essential for making up genetic material or DNA. Out of all given options, option 4 has both lentil and spinach (green leaves) which are rich source of folate. Option 1 has bread as a source of folate. Hence, the correct answer is option 4.
A test that combines radioactive chemicals and antibiotics to detect minute quantities of substance in a patient's blood is RBC nuclear scan.
It used small amounts of radioactive material that is marked as tag and red blood cell as RBC's. After this your body will be scanned to see the cells and tracking the movement of body.
This process firstly removing blood from a vein. Then RBC are separated from the rest of the blood. After this the cells are mixed with radioactive material. After a short time, the tagged RBC are injected into your veins.
Veins is a tube like structure that forms part of blood circulation system of the body, that carrying oxygen-depleted blood.

The suborganellar structure that will become visible after staining is nucleoid.
In the field of biology, nucleoid can be described as a region inside the prokaryotic cell in which the DNA is present.
The prokaryotes do not have a membrane-bound nucleus like the eukaryotes. Hence, the region where the genetic material of the prokaryotes is present is an irregular shaper structure referred to as the nucleoid.
When DNA is stained with a DNA-binding dye, the suborganellar structure that will become visible will be the nucleoid as it is the region where the DNA is present.
