Multiple choice zoology reproduction in organisms parthenocarpic fruits parthenogenesis the life cycle of plants

In honey bees, males (drones) are formed from

  1. Unfertilized eggs

  2. Fertilized eggs

  3. Embryo

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The male honey bees are called drones. Drones are formed from the unfertilized eggs i.e. haploid eggs of the queen bee. Fertilized eggs form queens and female workers. Drones are meant for mating with the queen bee and soon die after mating.
So, the correct answer is 'Unfertilised eggs'.
Multiple choice zoology reproduction in organisms parthenocarpic fruits parthenogenesis the life cycle of plants

Thelytoky, a type of parthenogenesis, occurs in

  1. Aphids

  2. Typhlina

  3. Honey Bee

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

The type of parthenogenesis in which females are produced from unfertilized eggs is known as thelytoky. The daughter cells produced are diploid in nature. It mainly occurs in aphids. It is mainly of two types, apomictic and automictic. 

So, the correct answer is option A.

Spiny ant eater belongs to

  1. Prototheria

  2. Metatheria

  3. Eutheria-Pholidota

  4. Eutheria-Insectivora
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Animals belonging to the subclass Prototheria lay eggs like non-mammals. But they feed their newborns with the secretions of their mammary glands. They are also called Monotremes as they have a single opening for both excretion and reproduction. There are only three surviving species of monotremes, spiny anteaters are one of them.

So, the correct answer is 'Prototheria'.

  2. Releaser pheromones

  3. Search image

  4. Territoriality

  5. Visual communication
Reveal answer Fill a bubble to check yourself
C Correct answer

    2. Pheromones are used as a form of communication between two mating species.
    3. A male generally marks it's territory inorder to avoid anymore competition for mating.
    4. Visual communication is primarly used to locate and identify the mating partner.
    So, the correct option is 'Search image'.
Multiple choice biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

Which of the following is the correct binomial nomenclature?

  1. APIS INDICA

  2. Trypanosoma gambiense

  3. Ficus Bengalensis

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

The various conventions followed while writing Binomial nomenclature are : 

1. It is conventional to write the first letter of the generic name with a capital and the first letter of the specific name with a small letter.
2. Scientific names must be underlined separately when written by hand.
In printed matter, these names are printed in Italic and underlined when handwritten.
In option A, all the letters are capitalized.
In option B, all conventions are followed.
In option C, the generic name is wrongly capitalized and not written in italics.
In option D, the name is not written in italics.
So, the correct option is 'Trypanosoma gambiense'.

Multiple choice biology control and coordination in living organisms hormones coordination in human beings- chemical control endocrine system in humans

Pheromones when secreted upon the skin surface, its odour generally affect 

  1. Skin colour

  2. Genitalia

  3. Breast

  4. Mutual behaviour of members of a species
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pheromones are the chemicals or compounds which have peculiar odour. These are secreted and released by the organisms with the help of glands present on the skin surface at various locations. These pheromones have odour which help in attracting the other member of the same species. The pheromone initiates a neuronal response and there is change in the physiolodical behaviour of the organism. There are various forms of pheromones like alarm pheromeones, food trail phereomeones and sex phereomones.

So, the correct answer is option D.
