Multiple choice biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

Both reptiles and birds share a number of anatomical features which led biologists to believe that birds descended from reptiles. What are those features?

  1. Presence of an egg tooth in the young at the time of hatching

  2. Lower Jaw made up of five parts

  3. Presence of only one occipital condyle

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

Since crocodiles plummet from a typical precursor with dinosaurs, they can give a helpful developmental correlation with feathered creatures. (In spite of their appearance, flying creatures are more firmly identified with crocs than reptiles are.). Fossilized skulls of child dinosaurs demonstrate a similar example they take after grown-up winged animals.

So, the correct option is 'All the above'.

The production of sounds by some insects by rubbing together parts of the body, usually to attract a female, is known as

  1. Undulation

  2. Stridulation

  3. Cacophony

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

Stridulation is the act of producing sound by rubbing together certain body parts. This behavior is mostly associated with insects, but other animals are known to do this as well, such as a number of species of fish, snakes and spiders. The mechanism is typically that of one structure with a well-defined lip, ridge, or nodules (the "scraper" or plectrum) being moved across a finely-ridged surface (the "file" or stridulitrum—sometimes called the pars stridens) or vice versa, and vibrating as it does so, like the dragging of a phonograph needle across a vinyl record. Sometimes it is the structure bearing the file which resonates to produce the sound, but in other cases it is the structure bearing the scraper, with both variants possible in related groups. Common onomatopoeic words for the sounds produced by stridulation include chirp and chirrup.

So the correct option is 'Stridulation'.

In frogs, body proportions do not change with their growth. A frog  that is twice as long as another will be  heavier by approximately ?

  1. Two-fold

  2. Six-fold

  3. Four-fold

  4. Eight-fold
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In frogs, body proportions do not change with their growth. This means that the weight and height of a frog increase and decrease proportionately. If one of these parameters increase, so does the other, and by the same proportion, and vice-versa. Hence, if a frog is twice as long as another, it will be approximately two times heavier also.

So, the correct answer is 'Two-fold'.

Multiple choice evs super senses sleeping time animal senses sense organs in animals

Sloth is considered as folivores because 

  1. They sleep for 17 hours.

  2. The bulk of their diets consists of buds, tender shoots, and leaves.

  3. They are carnivores

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

A folivore is an organism that is a specialized herbivore and eat leaves. Sloth is an animal that feeds on leave buds and tender shoot. Due to the low metabolic rate, they don't have to eat much. So, they only eat leaves to survive.

So, the correct answer is 'The bulk of their diets consists of buds, tender shoots, and leaves'.

Which of the following shows aestivation? 

  1. Bees

  2. Sparrow

  3. Rat

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

Aestivation is the type of summer sleep, performed by cold-blooded animals. It helps in maintaining the body temperature by avoiding the excessive water loss and any internal body damaged due to high temperatures. It is performed by bees, snails, earthworms, salamanders, frogs, earthworms, crocodiles, tortoise, etc.

So, the correct option is 'Bees'.

Receptors of pressure present in deep layers of skin are 

  1. Krause's end bulb

  2. Meissner's corpuscles

  3. Corpuscles of Ruffini

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

Meissner corpuscles are one of the three types of cutaneous receptors which are sensitive to fine touch. Three types are cutaneous receptors are sensitive to pressure which are namely Pacinian corpuscles, Ruffini endings and Krause end bulbs. Out of these, onion-shaped Pacinian corpuscles lie deep inside the dermis. The Ruffini endings are present deeper in epidermis near the base while the Krause end bulbs are present in specialized regions only, for example, conjunctiva of eyes, mucous membrane of lips and tongue etc. Thus, the correct answer is option D.

Which of the following organ senses temperature?

  1. Tongue

  2. Nose

  3. Skin

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Sensitivity to temperature is a skin sense that is related to the human need to maintain internal temperature balance or thermal homeostasis. 
  • When the body becomes hotter than the normal temperature the sweat glands releases sweat which in turns cools the skin as it evaporates. This helps the lower internal temperature of the body
  • Hence the organ which senses temperature is skin.
  • So, the correct answer is 'Skin'.

Which of the following have taste buds?

  1. Palate

  2. Mucous lining

  3. Tongue

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

Taste buds are sensory organs that are found on your tongue and allow you to experience tastes that are sweet, salty, sour, and bitter. Taste buds have very sensitive microscopic hairs called microvilli. Those tiny hairs send messages to the brain about how something tastes, whether if it is sweet, sour, bitter, or salty.

So, the correct answer is 'Tongue'.

Identify the sense organs.

  1. Eyes

  2. Nose

  3. Tongue

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Sense organs are organs of the body which responds to external stimuli by conveying impulses to the sensory nervous system. For example, eyes, nose, tongue, and ear.
  • We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin. Our brain receives signals from each of these organs and interprets them to give us a sense of what's happening around us.
  • So, the correct answer is 'All the above'.

Which of the following is a deep pressure receptor scattered in the dermis of our skin?

  1. Phonoreceptor

  2. Meissner's corpuscles

  3. Olfactory receptor

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

  • Photoreceptors - These are the structures responsible for light sensitivity.
  • Meissner's corpuscle - They are located in the upper surface of the skin and is sensitive to touch.
  • Olfactory organs - The organs that are responsible for the detection of smell.
  • Pacinian corpuscles - They are embedded deeply into the skin, below the layer of dermis or hypodermis. They act as the receptors for pressure on the skin.
So, the correct option is 'Pacinian corpuscles'.
