Explanation

Bees have been reported as the most efficient among insect pollinators due to their distinctive characteristics

both managed and wild bees provide pollination services to the vast majority of:

1. fruits,
2. vegetables,
3. forage crops (alfalfa and clovers),
4. oil-producing crops
5. and wild flowering plants 

Explanation

 new blue R can stain the body contents of dead Tylenchida ( ring nematode of woody plants)

while live nematodes remain unstained. 

Explanation

β adrenergic agonists, cause smooth muscle relaxation.

β2 adrenergic agonists' effects on smooth muscle 

Beta-2 agonists

1. trembling, particularly in the hands.
2. nervous tension.
3. headaches.
4. suddenly noticeable heartbeats (palpitations)

Explanation

There are three beta adrenoceptor subtypes:

1. beta-1,
2. beta-2,
3. and beta-3.

Explanation

Neuromuscular blocking drugs are often classified into two broad classes:

1. Pachycurares, are bulky molecules with nondepolarizing activity.
2. Leptocurares, are thin and flexible molecules that tend to have depolarizing activity

Explanation

Neuromuscular blocking agents (NMBAs) come in two forms: 

• Depolarizing neuromuscular blockers: Succinylcholine is the depolarizing neuromuscular blocker

• Nondepolarizing neuromuscular blockers:  can be divided into two classes based on their chemical structure:
  

steroidal (e.g., rocuronium, vecuronium, pancuronium) 

benzylisoquinolinium (e.g., mivacurium, atracurium, cisatracurium).

Explanation

The intramuscular administration of 0.6 mg of atropine sulfate to a 50 – kg adult may produce Decreased Salivation, Decreased Sweating, and  Mydriasis

Atropine Injection is given before anesthesia to decrease mucus secretions, such as saliva.

During anesthesia and surgery, atropine is used to help keep the heartbeat normal

The correct nomenclature for Down’s syndrome with translocation of chromosome 14 to chromosome 21 is depicted as 47 X Y, t(14;21)

***

A Robertsonian translocation can result in trisomy 14 or trisomy 21.

The acrocentric chromosomes include chromosomes 13, 14, 15, 21, and 22

Trisomy 21 is also known as Down syndrome
