  1. Distance of food source

  2. Direction of food source

  3. Both distance and direction of food source

  4. Distance and direction of enemy

Show answer
Correct Option: C
Explanation:

The waggle dance is a special 'figure of eight' dance that is done by the honey bee in its hive. By this, a worker tells the others where it has found nectar. It is done to give other bees information about the direction and distance to flowers that have nectar or pollen or both.

  4. Fats

Show answer
Correct Option: A
Explanation:

A mixture of monosaccharids sugars and other carbohydrates, Honey is mainly fructose(about $38\%$) and glucose(about $32\%$), with remaining sugars including maltose, Sucrose and other complex carbohydrates. It's glycemic index ranges from $31$ to $8$, depending on the variety.

  1. 10 m

  2. 50 m

  3. Less than 75 m

  4. More than 75 m.

Show answer
Correct Option: D
Explanation:
D) More than $ 75\,m $
As the food source becomes more distant the round dance is replaced by the waggle dance. The waggle dance includes information about the direction and energy required to fly to the goal. Energy expenditure is indicated by the length of time it takes to make one circuit.

An animal where male carries half the chromosomes present in female is?

  1. Amoeba

  2. Gorilla

  3. Honey Bee

  4. Geometrid Moth

Show answer
Correct Option: C
Explanation:

Bees have a different number of chromosomes. Females, workers and queens have 32, 16 are contributed by the queen's eggs and 16 come from the drones sperm. Since drones hatch from unfertilized eggs, they only have the 16 chromosomes that were in the egg. Drones are haploid because they only have one set of chromosomes.


So, the correct answer is 'Honey Bee'.

What is true in case of Honey Bee?

  1. Male diploid, female haploid

  2. Male diploid, female diploid

  3. Male haploid, female haploid

  4. Male haploid, female diploid

Show answer
Correct Option: D
Explanation:
In case of honey Bees, males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid (Haplodiploidy).

So, the correct answer is 'Male haploid, female diploid'.

Male produce sperms by mitosis in _______________.

  1. Periplaneta americana

  2. Apis mellifera

  3. Drosophila melanogaster

  4. Lepisma

Show answer
Correct Option: B
Explanation:
In organisms which have haploid males (such as honeybees, Apis mellifera), there is a variation of meiosis during spermatogenesis. The meiosis-I is abortive i.e. the chromosomal events such as crossover and separation of homologous chromosomes, do not happen. However, some cytological changes do happen which is described by Sharma et al (1961) as "simulation of the normal meiosis I". This is followed by meiosis II (which is mechanistically same as mitosis). So, basically there is no halving of the number of chromosomes and the gametes are also haploid.

So, the correct answer is 'Apis mellifera'.
