Here’s a breakdown of the statements in the context of the Anaemia Mukt Bharat (AMB) Strategy:
- Prophylactic calcium supplementation:
- Incorrect: AMB focuses on iron and folic acid supplementation, not calcium supplementation. Calcium supplementation is addressed under other maternal and child health programs.
- Campaign for delayed cord clamping at the time of childbirth:
- Correct: Delayed cord clamping is promoted as part of AMB to ensure improved iron stores in newborns, which helps prevent anaemia.
- Periodic deworming for children and adolescents:
- Correct: AMB includes periodic deworming to address parasitic infections, a significant cause of anaemia in children and adolescents.
- Addressing non-nutritional causes of anaemia:
- Correct: AMB recognizes non-nutritional causes such as malaria, hemoglobinopathies, and fluorosis in endemic areas and includes measures to address them.
Thus, statements 2, 3, and 4 are correct, and only statement 1 is incorrect.

The structure of an atom is made up of three particles: protons, neutrons, and electrons:
See lessProtons: Positively charged particles located in the nucleus
Neutrons: Uncharged particles located in the nucleus
Electrons: Negatively charged particles that orbit the nucleus in shells
The nucleus is a dense, positively charged part of the atom that contains more than 99.9% of its mass, even though it’s usually less than one ten-thousandth the size of the atom.
The arrangement and number of these particles in an atom determine its properties. For example, a hydrogen atom has one proton, one electron, and no neutrons.
To draw an atom structure, you can:
Draw a small circle to represent the nucleus
Write the number of protons and neutrons in the nucleus
Calculate the number of electrons in the atom
Draw the atom’s shells
Fill the shells with the correct number of electrons for the element
The number of protons and neutrons in an atom can be found on the periodic table. The top number is the mass number, which is the sum of the number of protons and neutrons. The bottom number is the atomic number, which is the number of protons.
