Diversity in Living Organisms

3,829 Questions

The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

Gorilla, chimpanzee and orangutan are some of the animals which resemble man in many _____ (i) _____. Among these animals, chimpanzee has the _____ (ii) _____ resemblance to man. In fact, the bone structure of all these animals has many similarities to that of man. Their constitution and the number of their teeth are _____ (iii) ______ to ours. Like human beings, they too have _____ (iv) ______  on their forehead. Their skulls are also like ours. Even their blood is _____ (v) _____ to ours. However, they cannot speak like us.

  1. same

  2. similar

  3. related

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

The passage discusses similarities between great apes and humans. The final sentence comparing blood composition requires establishing similarity, not identity. Blood from different primates is not identical (same would mean exact match), but it shares significant biochemical similarities (similar), making it useful for comparative studies. Related and close are less precise terms in this scientific context.

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

The passage describes physical similarities between humans and great apes. The context mentions features visible on the forehead that both species share. Great apes, like humans, have expressive facial skin including wrinkles on their foreheads. Eyes cannot be on the forehead, hair is present but not the focus, and the brain is internal - not a surface feature.

  1. conditions

  2. respects

  3. types

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

The phrase resemblance in many respects is a standard English idiom meaning similarities in multiple aspects or areas. Conditions refers to states or circumstances, types means categories, and factors are elements that influence something. None of these fit naturally with the verb resemble - you resemble someone in respects (aspects), not in conditions, types, or factors.

  2. less

  3. most

  4. closest
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Among great apes, chimpanzees are humans' closest living relatives, sharing approximately 98% of DNA. The blank requires a superlative form comparing resemblance levels. Closest is the correct superlative of close. Most would work with a base adjective like similar (most similar), but closest is the proper form when the root word is close.

  3. similar

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

The passage compares anatomical features of great apes and humans. The structure are _____ (iii) ______ to ours requires an adjective that can follow this form. Similar works correctly: are similar to ours. More is incorrect because more...to is ungrammatical (more requires than). Just like doesn't work because the structure would be are just like ours (no to needed). Better makes no sense in this comparison context.

Directions: Read the passage carefully and choose the correct answer to the numbered blank.

Kangaroos are animals _____(i)______ only in Australia. They are called marsupial animals because they are the only mammals that _____(ii)______ their young ones in a pouch outside their bellies. They are very powerful animals. Kangaroos _____(iii)______strong and long hind legs. They use these to hop. They use their long and _____(iv)_____ tails to balance their bodies while _____(v)_____.

  1. born

  2. found

  3. left

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

In the context of the passage, 'found' is the correct word because it indicates where kangaroos exist geographically - they are found only in Australia. 'Born' would imply they originate only there (which is true but doesn't fit the context of location), while 'left' and 'taken' don't make sense in this context of geographical distribution.

  1. curved

  2. thin

  3. powerful

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

The word 'powerful' is the correct choice because the tail must be strong and muscular to effectively balance the kangaroo's body while hopping. The passage earlier describes kangaroos as 'very powerful animals,' and this description logically extends to their tails, which are crucial for their movement. 'Curved,' 'thin,' and 'straight' don't convey the necessary strength.

  1. create

  2. have

  3. use

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

'Have' is the correct verb to complete the sentence structure 'Kangaroos have strong and long hind legs.' The sentence is describing a physical attribute that kangaroos possess. 'Create' doesn't make sense as they don't create their legs. 'Use' would require 'use' to 'hop' which doesn't fit grammatically. 'Display' is not appropriate for describing possession of a physical characteristic.

They are very powerful animals. Kangaroos _____(iii)______strong and long hind legs. They use these to hop. They use their long and _____(iv)_____ tails to balance their bodies while _____(v)_____.

  1. hopping

  2. springing

  3. jumping

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

'Hopping' is the correct action because kangaroos use their tails specifically to balance while hopping, which is their primary mode of locomotion. The sentence 'They use these to hop' earlier in the passage directly references this movement. While 'bouncing' and 'jumping' are similar, 'hopping' is the specific term for kangaroo movement. 'Springing' is not typically used to describe kangaroo locomotion.

Multiple choice

Directions: Sometimes we conclude about characteristics of a general phenomenon by studying or analyzing characteristics of a particular phenomenon. Below are given such inductive arguments. The generalization is given first, followed by a particular statement. You have to find out whether the numbered particular statement strongly confirms, vaguely hints, contradicts, or is irrelevant to the generalisation. Read the question below and answer accordingly.

Generalisation: Predatory animals have eyes in the front of their heads, with overlapping visual fields.

  1. All felines have eyes in front of their heads.
  2. Horses have eyes on the sides of their heads, with visual fields that do not overlap. What type of support does statement (I) provide for this generalisation?

  1. Strongly confirms

  2. Vaguely hints

  3. Contradicts

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

Felines are examples of predators. Hence, statement 1 confirms the generalization.

Multiple choice

Which of the following statements regarding prokaryotic extracellular appendages are TRUE? P. Bacterial glycocalyx is located inside the cell wall. Q. Bacterial capsule is a well organized bacterial glycocalyx. R. F pili is involved in transferring DNA from one bacterium to another. S. Fimbriae help bacteria to attach to the other structures.

  1. P and Q

  2. P and R

  3. Q and R

  4. Q and S

  5. Q, R and S
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Bacterial capsule is a well organized bacterial glycocalyx that is firmly attached to the bacterial cell wall. F (conjugation, sex) pili are involved in the transfer of plasmids from one bacteria to the other. Fimbriae are short pili found in large numbers and used to attach bacteria to surfaces.
