Multiple choice biology biodiversity and classification animal classification and its benefits criteria for new system of classification five kingdoms of living organisms

Kingdom Animalia are classified into

  1. Phylum Porifera

  2. Phylum Arthropoda

  3. Phylum Chordata

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Kingdom Animalia is classified into 36 phyla on the basis of similarity and dissimilarity. Phyla are further divided into the class.
Phylum Porifera belongs to the animal kingdom which has the cellular level of organization.
Phylum of the animal kingdom which has tissue level of organization are Arthropoda, Platyhelminthes, Nematoda, Cnidaria, Annelida, Echinodermata, Mollusca and Chordata.
Thus, the correct answer is option D.

Multiple choice biology biodiversity and classification animal classification and its benefits criteria for new system of classification five kingdoms of living organisms

An organisms lacks complete digestive tract is

I. Jellyfish
II. Mollusk
III. Earthworm

  1. I, II and III

  2. I only

  3. II only

  4. III only

  5. I and III only
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Jellyfish have an incomplete digestive system as the same orifice is used for both food intake and waste expulsion. Mollusk and earthworm have a complete digestive system with distinct openings for food intake and waste expulsion. 

Therefore, the correct answer is option B.

Amniotic membranes are formed in
I. Amphibians
II. Birds
III. Mammals
IV. Reptiles

  1. I, II and IV

  2. II and III

  3. II, III and IV

  4. I and IV

  5. IV only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Amniotic membrane is the innermost layer of the placenta consisting of a thick basement membrane and an avascular stromal matrix. This is a thin tough and transparent  pair of membranes that form a sac in which the fetus of tetrapods vertebrates such as reptiles, birds and mammals develop. Thus, the correct answer is option C.

The statements given in the box describe an animal. Identify the animal.

$\bullet$ It is a carnivore.
$\bullet$ It lives in a forest.
$\bullet$ It is being wiped out by poachers killing them for their skin, bones, nails and teeth.

  1. Chinkara

  2. Black buck

  3. Tiger

  4. Chiru
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Tiger is a carnivore animal which feeds on the flesh of the other organisms. This animal is commonly found in the forests. Due to the activity of the poachers and hunters, the number of these animals have been greatly reduced. The animals are hunted for the skin, bones, teeth and nails. The project tiger was initiated to protect the tigers.

Thus, the correct answer is option C.

Explanation

Kingdom Animalia consists of organisms that range from the simplest of the animal forms to the most complex. 
Currently 1.7 million living organisms are known to science. Out of these 1.2 million are animals and about 0.5 millions.

Hence the correct answer is option D. 

Multiple choice biology biodiversity and classification animal classification and its benefits criteria for new system of classification five kingdoms of living organisms
ORGANISM Jaws Lungs Amniotic Membrane Hair No tail Bipedal
Lamprey 0 0 0 0 0 0
Shark 1 0 0 0 0 0
Salamander 1 1 0 0 0 0
Lizard 1 1 1 0 0 0
Tiger 1 1 1 1 0 0
Gorilla 1 1 1 1 1 0
Human 1 1 1 1 1 1

For the data table shown above, a 1 indicated that the trait is present and a 0 indicates that the trait is absent.
Which of the following statements represents an accurate interpretation of the data?

  1. All organisms in the table share all of the derived characteristics.

  2. Only humans and gorillas share all of the derived characteristics.

  3. Because it shares none of the derived characteristics, lampreys constitute an out-group.

  4. Because it shares just one of the derived characteristics, sharks can be considered an internal branch of the phylogenetic tree.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

From the table, it is seen that except Lamprey, all organisms share derived characteristics. Because it shares none of the derived characteristics, it constitute an out-group. Humans and gorillas share most of the derived characteristics. Because it shares just one of the derived characteristics, sharks can be considered an outer most branch of the phylogenetic tree.

Thus, the correct answer is 'Because it shares none of the derived characteristics, lampreys constitute an out-group.'

Study of ticks and mites is called

  1. Acarology

  2. Entomology

  3. Malacology

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

Ticks and mites are the groups of organisms that belong to the family Arthropoda and subclass Acarina. So the study of these Acarina organisms is called as acarology.

Entomology as the name indicates it is the study of insects.
Malacology is the study of Molluscs that belongs to zoology
Carcinology is the branch of science that deals with the study of organisms like crayfish etc., that belongs to crustaceans. Thus, the correct answer is option A.

Maximum nutritional diversity is found in the group _________.

  1. Fungi

  2. Animalia

  3. Monera

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

Fungi take their nutrition by absorbing organic compounds from the surrounding environment. Monera kingdom contains unicellular prokaryotic organism. Kingdom Plantae consists of multicellular photosynthetic eukaryotes. Kingdom Animalia has multicellular eukaryotic  organisms which consume organic matter and hence maximum nutritional diversity is found in this group.

The correct answer is B.

Animals with self fertilization is

  1. Paragonimus

  2. Dugesia

  3. Taenia solium

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In Taenia solium both self-fertilization and cross-fertilization occur. In self-fertilization, sperms produced in proglottid fertilize the ova produced in the same proglottid. In cross-fertilization, sperms produced in a proglottid fertilize ova produced in another mature proglottid of the same worm. In paragonimus and dugesia self-fertilization is absent.
