(A) assessing psychological stress

(B) assessing nutritional status

(C) planning and prioritising nutrition intervention(s) to meet nutritional needs

(D) diagnosis of nutritional problems

2. planning and prioritising nutrition intervention(s) to meet nutritional needs

3. diagnosis of nutritional problems

Q :  

Which are the smallest cells in the human body?   

(A) Muscle cells

(B) Nerve cells

(C) Sperm cells

(D) Brain Stem cells

Correct Answer : C
Explanation :

The sperm cell is the smallest cell in the human body. The volume of these cells is quite tiny. The head of a sperm cell is roughly 4 micrometres long, about the same size as a red blood cell (RBCs). Egg cells are the biggest cells in the human body (ovum).

Q :  

Which is a major essential lipophilic (fat-soluble) vitamin required for the protection of cell membranes and the formation of red blood cells (RBCs)?

(A) Vitamin A

(B) Vitamin C

(C) Vitamin D

(D) Vitamin E

Correct Answer : D
Explanation :

Vitamins A, D, E, and K are called the fat-soluble vitamins, because they are soluble in organic solvents and are absorbed and transported in a manner similar to that of fats. Vitamin E deficiency, which is rare and usually due to an underlying problem with digesting dietary fat rather than from a diet low in vitamin E, can cause nerve problems.

Q :  

In which year did Rudolf Virchow published an essay titled ‘Cellular Pathology’ in which he famously declared that "every cell arises from another cell”?

(A) 1865

(B) 1835

(C) 1845

(D) 1855

Correct Answer : D
Explanation :

n 1855, at the age of 34, he published his now famous aphorism “omnis cellula e cellula” (“every cell stems from another cell”). With this approach Virchow launched the field of cellular pathology. He stated that all diseases involve changes in normal cells, that is, all pathology ultimately is cellular pathology.

Q :  

In 1928, who discovered that when a ray of coloured light enters a liquid, a fraction of the light scattered by that liquid is of a different colour?

(A) SN Bose

(B) Lord Rayleigh

(C) CV Raman

(D) John Tyndall

Correct Answer : C
Explanation :

Sir Chandrasekhara Venkata Raman, discovered on 28 February 1928, that when a beam of coloured light entered a liquid, a fraction of the light scattered was of a different color, dependent on material property. This radiation effect of molecular scattering of light bears the name of ‘Raman Effect’, from which many applications in photonic communications and spectroscopy evolved. The Raman Effect is the process of scattering light particles by molecules of a medium.

Q :  

Which of the following glands/organs in human body secretes bile juice?

(A) Pancreas

(B) Liver

(C) Pituitary

(D) Pineal

Correct Answer : B
Explanation :

Bile juice is produced by the liver and stored in the gallbladder, which is a small organ located beneath the liver. When needed, bile is released from the gallbladder into the small intestine to aid in the digestion and absorption of fats and fat-soluble vitamins. So, the correct answer is the liver secretes bile juice, and it is stored in the gallbladder before being released into the small intestine.

(D) Junction point

Correct Answer : B
Explanation :

The junction between the axon of one neuron and the dendrite (or cell body) of the next neuron is called a synapse. At the synapse, electrical or chemical signals are transmitted from one neuron to another or to an effector cell, such as a muscle cell or gland cell. Synapses play a crucial role in the transmission of nerve impulses within the nervous system.
