"Mother-of-Pearl" is

biology biological diversity species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. A hard iridescent substance forming the inner layer of certain shells

  2. A special large sized pad found in Japan

  3. An oyster which yields the pearl

  4. A title given to Queen Victoria on becoming the Empress of India

Show answer
Correct Option: A
Explanation:

Nacre, also known as the mother of pearl, is an organic-inorganic composite material produced by some molluscs as an inner shell layer; it also makes up the outer coating of pearls. It is strong, resilient, and iridescent. So, the correct option is A. ( A hard iridescent substance forming the inner layer of certain shells )

Snakes are

biology kingdom animalia species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. Viviparous

  2. Oviparous

  3. Herbivores

  4. None of the above

Show answer
Correct Option: B
Explanation:

Snakes lay eggs and are hence Oviparous and not Oviparous.

Snakes are carnivores as they eat other small prey like rats, birds, etc.
So the correct answer is 'Oviparous'. 

The animals that give birth to young ones are

biology kingdom animalia species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. Reptiles

  2. Birds

  3. Amphibians

  4. Mammals

Show answer
Correct Option: D
Explanation:

Mammals are the warm-blooded vertebrate animal that is distinguished by the possession of hair or fur, females that secrete milk for the nourishment of the young. They give birth to young ones so they are known as viviparous.
So, the correct answer is 'Mammals'.

Which one is true of male gamete of angiosperms?

biology biological diversity species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. Large nucleus

  2. Thick sheath of cytoplasm

  3. Thin sheath of cytoplasm devoid of ce organelles

  4. Both B and C

Show answer
Correct Option: A
Explanation:

Pollen grains form the first cell of male gametophytic generation.It divides into two unequal cells; a small generative cell and a larger vegetative cell. During the germination of pollen tube over the carpel, the vegetative tube nucleus migrates into the pollen tube and reaches up to the distal end. The generative cell also migrates into the pollen tube and divides to form two male gametes. Each male gamete consists of a large nucleus surrounded by a thin sheath of cytoplasm. 

Thus, the correct answer is option A. 

Which of the following is correct in case of  homosporous pteridophytes?

biology biological diversity species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. All the sporangia are similar

  2. Male and female gametophytes exist

  3. Two different types of spores are present

  4. None of the above

Show answer
Correct Option: A
Explanation:

Homosporous pteridophytes produce only one type of spores. Also, all the sporangia in a homosporous pteridophyte are similar.

So, the correct option is 'All the sporangia are similar'.

The zygote of angiosperms is

biology biological diversity species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. Haploid

  2. Diploid

  3. Triploid

  4. Polyploid

Show answer
Correct Option: B
Explanation:
  • In angiosperms, as the pollen tube penetrates the ovule, it releases two sperm cells. One fuses with the egg to create a diploid zygote which develops into an embryo, while the other joins with the fusion nucleus to form a triploid nucleus that develops into endosperm.
  • So the correct answer is ' Diploid'.

Which of the following external characters help in differentiating a male cockroach from a female one? 

biology biological diversity species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. Abdominal segments

  2. Anal cerci

  3. Anal styles

  4. Antennae

Show answer
Correct Option: C
Explanation:

Anal style are a pair of thread like appendages arising from the 9th segment of the male cockroaches. They are characteristic feature of male cockroaches and help in copulation.

So, the correct option is 'Anal Styles'.

The blood of cockroach contains no heamoglobin. It means that

biology biological diversity species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. Oxygen goes directly into tissues by diffusion

  2. Respiration is anaerobic

  3. Cockroach does not respire

  4. Oxygen goes, directly into intracellular capillary system

Show answer
Correct Option: A
Explanation:

Cockroach blood is not red because they do not use hemoglobin to carry oxygen. In fact, their bloodstream is not used to carry oxygen either. They use a system of pipes called tracheae to bring the oxygen and remove carbon dioxide from their tissues and oxygen goes directly into tissues by diffusion. So, the correct option is A. ( Oxygen goes directly into tissues by diffusion )
