Questions Related to diversity and classification in animals

Desert lizard is an example of:

  1. Regulator

  2. Conformer

  3. Behavioral regulator

  4. Partial regulator

Show answer
Correct Option: B
Explanation:

Regulators are those animals that can regulate their body temperature by their own, according to the environment and their need while conformers are those animals that cannot regulate their body temperature and require sun to increase their body temperature. The conformers are also called cold-blooded animals. Some of the examples of conformers are desert lizards, fishes, snakes etc.

So, the correct option is 'Conformer'.

Terrestrial animals must

  1. Excrete large amounts of urine

  2. Conserve water

  3. Activity pump out salts through skin

  4. Excrete large amount of salts in urine

Show answer
Correct Option: A
Explanation:

  • Terrestrial organism conserves water as to them less water is available.
  • The urine thus produced is concentrated releasing urea or ammonia.
  • Since ammonia needs a lot of water to get released from the body.
So, the correct option is 'Excrete a large amount of water'.

Legs of this animal are adapted for running at great speed

biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

  1. Rhinoceros

  2. Deer

  3. Frog

  4. Kangaroo

Show answer
Correct Option: B
Explanation:
  • Deer are the hoofed ruminant mammals. The deers have long legs with powerful muscles and are able to run 40 miles per hour and jump 10 feet high.
  • They are also fast swimmers. Deer have an excellent sense of smell, which allows them to detect predators from a long-distance away.
  • So, the correct answer is 'Deer'.

Animal that lives only in water and also reproduces in water is

biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

  1. Frog

  2. Crocodile

  3. Turtle

  4. Fish

Show answer
Correct Option: D
Explanation:
  • Fish lives only in water because the gills of the fish which act as a respiratory organ, can take oxygen only from water and not from the air. Hence it is necessary for them to live in water. 
  • Fertilization is external in most fish species. Large quantities of eggs and sperm are simultaneously released into the water by females and males. This process of egg release is termed spawning.
  • So, the correct answer is 'Fish'.

The hump of camel helps in storing

biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

  1. Water

  2. Grass

  3. Fat

  4. Urine

Show answer
Correct Option: C
Explanation:
A camel is adapted for xeric (desert) conditions. The following adaptations are found in a camel:
1. Its hooves are covered by a large sole which helps it to move on the hot slippery sand.
2. It has a hump on the back which is filled with fat. This food is utilized when the camel does not get anything to eat.
3. Water gets evenly distributed in different parts of its body and not in a specific pocket or an organ.
4. It excretes very little water from its body.
So, the answer is C.

Which of the following breed of sheep found only in Uttar Pradesh and Himachal Pradesh?

  1. Bakhar wal

  2. Rampur Bushair

  3. Nali

  4. Lohi

Show answer
Correct Option: B

Study following statements and choose the correct alternative.
(P) Those organs which have the same internal structure but different functions, are called homologous organs.
(Q) Organs which have different basic design but have similar appearance and carryout similar functions are called analogous organs.
(R) The impressions of dead plants or animals that lived in the past are known fossils.

  1. All the three (P, Q, R) statements are true

  2. Statements P and Q are true but R is false

  3. Only R is true

  4. All three statements are wrong

Show answer
Correct Option: A
Explanation:

The organs which have the same structure but are involved in performing the different type of functions are known as homologous organs. 

The organs which have similar functions but are structurally different are known as the analogous organs. 
The fossils are the imprints, casts or molds of the dead animals and plants which existed in the past. These fossils are used for the study of the ancient organisms. 
Thus, the correct answer is option A. 

Which of the following is incorrect match?

biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

  1. Polar bear - Eurythermal

  2. Archaebacteria - Hydrothermal vents

  3. Cyanobacteria - Thrive in Antarctic water

  4. Desert lizards - Body temperature fairly constant

Show answer
Correct Option: A
Explanation:
  • Polar bears are stenothermal because they can tolerate only a narrow range of temperature and are restricted to specific regions only. On the other hand, eurythermal animals can tolerate a wide range of temperature variations and thus have a wider distribution on earth.
  • Archaea are microorganisms that define the limits of life on Earth. They were originally discovered and described in extreme environments, such as hydrothermal vents and terrestrial hot springs. 
  • Cyanobacteria can be found in almost every terrestrial and aquatic habitat—oceans, freshwater, damp soil, temporarily moistened rocks in deserts, bare rock, and soil, and even Antarctic habitats, some of the driest and coldest ecosystems on the Earth.
  • Ectotherms like desert lizards do not use metabolic heat to maintain their body temperature but manage to keep their body temperature fairly constant by behavioural means. They bask in the sun and absorb heat when their body temperature drops below the comfort zone but move in to shade when the ambient temperature starts increasing.
  • So the incorrectly matched option is A.

Dominance hierarchies are most common when

biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

  1. resources are uniformly distributed throughout the environment

  2. resources are concentrated in one part of the environment

  3. parental care is wanting

  4. males are larger than females

Show answer
Correct Option: A
Explanation:

Dominance hierarchy is a type of social hierarchy that arises when members of a social group interact, to create a ranking system. In social living groups, members are likely to compete for access to limited resources and mating opportunities. In most cases the dominance hierarchy is relatively stable from day to day. 

So the correct option is 'resources are uniformly distributed throughout the environment'. 

Assertion  :  The functional unit of excretory organs of
                       lobsters is nephron

Reason  :      The filtration of blood occur in the
                      malpighian body (the glomerulus and
                     Bowman's capsule).

  1. If both the assertion and the reason are true and the reason

    is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is

    not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true

Show answer
Correct Option: D
Explanation:

Nephron is the principal functional unit of the kidney of vertebrates. Its number reaches to one million in each kidney. Filtration of blood occurs in Malpighian body, later is composed of a tuft of capillaries called the glomerulus together with the cupped end of the renal tubules,
known as Bowman's capsule.
