The contrast in the development and social behavior of the western honey bee, Apis mellifera, has been shown to depend on whether bee larvae are fed royal jelly or not.
Those larvae fed jelly will accelerate growth and become queens; all others are destined to become drones. The drastically different developmental outcomes occur despite equivalent genomes, suggesting an epigenetic mechanism.

Which of the following choices would be a feasible mechanism to investigate?

  1. Recombination of genomic DNA leading to the loss and expression of relevant genes.

  2. Post-translation modification leading to altered function of the proteins involved in development.

  3. Methylation of histone proteins or genomic DNA resulting in the silencing of genes.

  4. Examining the jelly for genetic material that when incorporated into the larvae, promote the royal pathway.

A Correct answer
Explanation

A- Recombinant DNA technology is utilized to alter a known DNA sequence from one organism and introduce it into another organism by modifying the genotype. Genetic recombination permits new genetic combinations accelerating the genetic diversity in a particular population thereby, leading to the loss & expression of the relevant genes. Genetic recombination results in the evolution in response to the changes in the environment.

The stimuli through which a dancing scout bee communicates the location of a food source to other worker bees in a hive are 

  1. Visual

  2. Acoustic

  3. Contact

  4. Contact and visual
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Honey bees like insects communicate through chemicals and odors. Besides these they also use specific behaviors such as dances to convey information about the availability and type of resources in the environment, and the location of the same. The dancing scout bee's body generally points in the direction of the food source and the sound produced during the dance indicates the profitability and availability of food. Hence, the scout bee uses acoustic stimuli to communicate the location and source of food to other worker bees.

In honey the percentage of maltose and other sugar is ...........%

  1. 9.2

  2. 8.81

  3. 10.5

  4. 11.2
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Honey is mainly consists of fructose (about 38-55%) and glucose (about 31%), with remaining sugars including maltose, sucrose, and other complex carbohydrates. Maltose, sucrose and other sugars accounts for 8.8%. Hence, option B is correct.

Nobel prize winner for the discovery of method of interpersonal communication in honey bee is ......................

  1. Karl von Frisch

  2. H.G. Khorana

  3. Harvey

  4. Darwin
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Karl von Frisch of Germany was awarded Nobel prize in 1973 for his discovery in the field of organisation and elicitation of individual and social behaviour pattern in bees. He showed that honey bees use a dance language to communicate food locations to other bees. He found two types of dance - round and waggle dance. Hence, option A is correct.

Sting apparatus in honey bee is a modified form of ...............

  1. Ovipositor

  2. Wax glands

  3. Alkaline glands

  4. Podical valves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The stinging apparatus of the honey bee is a modified ovipositor (egg laying tube) that all bees and wasps have. In some bees and wasps, the ovipositor is nothing more than a simple egg-laying tube designed to get eggs into hard to reach nooks, while in others it is stiffened to allow holes to be made in wood or penetrate the bodies of other insects in order to lay eggs. As the stinger is a modified egg laying tube, only the female bees posses a sting.

 Which is wrong about Bee colony

  1. Sex differentiation is based on haplodiploidy

  2. Female dominated society

  3. Domesticated species are A. indica and A. mellifera

  4. Fertilized eggs develop into sterile females only.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In a bee colony, fertilized eggs develop into females (queens or workers), not just sterile females. The queen is a fertile female.

  1. Apis indica is the largest species is India

  2. Bees wax is wasteful product

  3. Honey has glucose and arabinose as main constituents

  4. Communication in bees was first studied by Frisch.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Karl von Frisch was a Nobel Prize-winning ethologist who famously decoded the 'waggle dance' used by honey bees to communicate the location of food sources.
