The hormone that controls the level of calcium and phosphorus in blood is secreted by parathyroid gland.

Parathyroid gland is tiny glands. It controls the body’s calcium level. Each gland is about the size of a grain of rice. Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney.

Spina bifida is one of the possible neural tube defects that can occur during early embryological development.

Meningocele is a sac formation containing meninges and cerebrospinal fluid (CSF). Meningocele is the simplest form of open neural tube defect characterized by cystic dilatation of meninges containing cerebrospinal fluid without any neural tissue. A complex meningocele is associated with other spinal anomalies. Meningocele is a typically asymptomatic spinal anomaly and is not associated with acute neurologic conditions.

The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. DNA must be compacted into nucleosomes to fit within the cell nucleus.

Two molecules of acetyl co-A condense to form acetoacetyl co-A, which condenses with the third molecule of acetyl co-A to yield a six-carbon compound HMG co-A.

Hippocampus part of the brain is responsible for transferring short-term memory to long-term memory.

Hippocampus is a region of the brain which is primarily associated with memory. It is derived from the Greek word hippokampos (where hippo means 'horse' and kampos means 'sea horse') as the shape of its structure is similar to the sea horse. It plays an important role in the consolidation of information from short-term memory to long-term memory.

The theory of cognitive development was proposed by Jean Piaget. Jean Piaget's theory of cognitive development suggests that children move through four different stages of mental development. His theory focuses not only on understanding how children acquire knowledge, but also on understanding the nature of intelligence.

Article 342 of the constitution deals with specifying a particular tribe as a scheduled tribe.

Article 342 provides for specification of tribes or tribal communities or parts of or groups within tribes or tribal communities which are deemed to be for the purposes of the Constitution the Scheduled Tribes in relation to that State or Union Territory.

Diplopia is an early clinicalmanifestation of increased ICP in olderchildren.

Diplopia is an early sign of increased ICP in an older child. Visual changes can range from blurred vision, double vision from cranial nerve defects, photophobia to optic disc edema and ultimately optic atrophy. Clinical suspicion for intracranial hypertension should be raised if a patient presents with the following symptoms: headache, vomiting, and altered mental status varying from drowsiness to coma.

Plant diseases can be infectious (transmitted from plant to plant) or noninfectious. Common plant disorders are caused by deficiencies in plant nutrients, by waterlogged or polluted soil, and by polluted air. Too little (or too much) water or improper nutrition can cause plants to grow poorly. Plants can also be stressed by weather that is too hot or too cold, by too little or too much light, and by heavy winds. Pollution from automobiles and industry, and the excessive application of herbicides (for weed control) can also cause noninfectious plant disorders.

L-Glutamate is the most abundant free amino acid in brain and it is the major excitatory neurotransmitter of the vertebrate central nervous system. Most free L-glutamic acid in brain is derived from local synthesis from L-glutamine and Kreb's cycle intermediates.

The term used for describing a child's one-word utterances is Holophrases.

When the child is about twelve months old, he/she start to say some words, usually single words. These single words are referred to as Holophrases. As an instance, a child says 'mine' to mean 'this toy is mine', and like that, there are more single words a child speaks when he/she begin to talk.

Power dissipation is given by:

Power

Where V is the potential difference across resistance, I is current flowing and R is resistance.

Given: Power (P) = 800W; Voltage (V) = 200V; Current (I) = ?

The electric power of an electric heater is given by:

Power (P) = VI  
800 = 200 x I
I = 4A

The control of interest of banks is based on the recommendation of Narsimha Committee, with the aim to examine all aspects of the financial system's structure, system, functions, etc.

When a drug binds to a receptor to produce a pharmacologic effect, the drug may be called an Agonist.

Agonist and blocker are synonymous. An agonist is a drug that activates certain receptors in the brain. An agonist is a medication that mimics the action of the signal ligand by binding to and activating a receptor.

The Government of India intends to launch PM PRANAM (programme for restoration, awareness, nourishment and melioration of mother earth) scheme to reduce the use of chemical fertilizers by incentivizing states.

Koyna river does not join the Gulf of Khambhat.

The Food Safety and Standard Association of India (FSSAI) awarded Bhopal Railway Station a 4-star ‘Eat Right Station’ certification.

It has been provided the certification for providing "high-quality, nutritious food to passengers". The certification is part of the ‘Eat Right India movement- a large-scale effort by FSSAI to ensure safe, healthy, and sustainable food for all Indians.

Post-1991 LPG reforms the tertiary sector has grown more than others. It contributes about 54% to GDP employing 31% workforce. The highly educated English speaking labour in the country has taken advantage of this growth.

Nursing diagnoses mostly differ from medical diagnoses, in that they are primarily concerned with human response, while medical diagnoses are primarily concerned with pathology. Nursing diagnoses mostly differ from medical diagnoses, in that they are: dependent upon medical diagnoses for the direction of appropriate interventions. primarily concerned with caring, while medical diagnoses are primarily concerned with curing.

Mr. Bikas has renal calculus, age 35. He is believed to have a small stone that will pass spontaneously. To increase the chance of renal stone passing, the nurse would instruct the client to force fluids and to Ambulate.

Unattached stones in the urinary tract can be passed out with the urine by ambulation which can mobilize the stone and by increased fluid intake which will flush out the stone during urination.

You will expect the nurse to administer the vaccine Subcutaneously in the outer aspect of the upper arm routes.

The subcutaneous route allows drugs such as insulin and heparin to be absorbed slowly over a period of time. Using the correct injection technique and selecting the correct site will minimise the risk of complications.

The pattern followed here is:

Similarly,

• According to the English Alphabet series and its positional value:
• The letters are arranged in such a way that one letter has been skipped between J and L, three letters have been skipped between L and P, five letters have been skipped between P and V and so on as per the English alphabetical series.
• Following the same pattern, eleven letters will be skipped between N and the next letter as per the English alphabetical series.
• The pattern in the series involves adding consecutive even numbers to the position of each letter in the alphabet:
  • J is the 10th letter. Adding 2 gives 12, which is L.
  • L is the 12th letter. Adding 4 gives 16, which is P.
  • P is the 16th letter. Adding 6 gives 22, which is V.
  • V is the 22nd letter. Adding 8 gives 30. Since there are only 26 letters in the alphabet, subtract 26 from 30 to get 4, which is D.
  • D is the 4th letter. Adding 10 gives 14, which is N.
  • N is the 14th letter. Adding 12 gives 26, which is Z.
• Therefore, the next letter in the series is Z.

So, Z will replace the question mark (?) in the given series.

Numbers of the form are added, where n is natural number

Thus, missing alphabet = F

Eosinophils are revealed in sputum by microscopy of a smear stained by Romanowsky or Leishman.

Leishman stain, also known as Leishman's stain, is used in microscopy for staining blood smears. It is generally used to differentiate between and identify white blood cells, malaria parasites, and trypanosomas.

Romanowsky-type stains are used to differentiate cells for microscopic examination in pathological specimens, especially blood and bone marrow films, and to detect parasites such as malaria within the blood.
