A behavioral strategy of adaptation called echolocation is found in 

  1. bats

  2. butterfly

  3. praying mantiis

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

Bats are nocturnal flying mammals which do not employ eyesight for location of their path. food place of rest etc. They produce high frequency sound which produces echoes after striking various objects on the principle of sonar. Echoes are then analysed by bats to know their path.

Raj was swimming in a pond. When he walked back to his car, he noticed that several newly hatched ducklings were following his moves. Which among the following explains it correctly?

  1. Tropism

  2. Conditioning

  3. Sympathetic nervous system

  4. Associative learning

  5. Imprinting
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation
  • Tropism is referred to as the response to a stimulus.
  • Conditioning is a behavior where the response comes from frequent predictable consequences.
  • The sympathetic nervous system regulates the unconscious actions.
  • Associative learning is when a new response becomes associated with a particular stimulus.
  • Imprinting is a way of learning at a certain phase of life in which the organism follows the surrounding environment.  It is generally seen at the early hours of a newborn. It helps in the vocational development of organisms.
So, the correct option is 'Imprinting'.

B Correct answer
Explanation
When two or more people encounter each other, sooner or later one of them will speak or give some indication of acknowledging the presence of others. This is called the transactional stimulus. The other person will then say or do something which is in some way related to the stimulus, and that is called the transactional response.

It is difficult to climb the steps having greater inclination. Why?

  1. Less erect steps require less energy

  2. Greater inclination requires less effort because of the high mechanical advantage

  3. Greater iriclination requires more effort because of the low mechanical advantage

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

As steps become more inclined, the vertical height gained per step increases, requiring more work against gravity. This reduces the mechanical advantage because a greater portion of the applied force goes into lifting vertically rather than moving forward.

Migration in birds is guided in part by-

  1. Celestiial navigation

  2. Temperature chnages

  3. Territorial aggression

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

Birds that nest in the Northern Hemisphere tend to migrate northward in the spring to take advantage of burgeoning insect populations, budding plants and an abundance of resting locations. This is guided by celestial navigation with a sextant.

So, the correct option is 'Celestial navigation'.

The bye-bye gesture, we do using hands is an example of 

  1. Periodic motion

  2. Oscillatory motion

  3. Linear motion

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

The motion of the hand is an oscillatory motion, as the motion repeats in a finite interval of time and the to and fro motion happens in a given time period

As the hand moves to one extreme, a restoring force acts in the opposite direction to move it back to the mean and then to the other extreme position. Thus, the bye-bye gesture of the hand is an oscillating motion


The correct option is (b)

Imitation is

  1. Involuntary response

  2. Voluntary response

  3. Stimulus

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

A) An involuntary response is not under conscious control. It generally constitutes the reflexes.

B) A voluntary response is controlled by our consciousness.
Imitation is controlled by our consciousness as when we imitate; we observe, learn and then reciprocate. 
C) Stimulus is the input to one's body, it can be either external or internal.
So, the correct option is 'Voluntary response'.

Multiple choice biology movement and locomotion in living organisms movements in plants coordination in plants tropic and nastic movements in plants

Movement of tendrils is

  1. Hydrotropism

  2. Chemotropism

  3. Thigmotropism

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

Most vines and other climbing plants have tendrils that coil rapidly around supports. These grasping organs usually grow straight until they touch something; the contact stimulates a coiling response caused by differential growth of cells on opposite sides of the tendrils, the directional growth in response to touch is called thigmotropism, and it allows the vine to take advantage of whatever mechanical supports it comes across as it climbs upward toward a forest canopy.

Zig-zag movement is

  1. Hyponastic

  2. Nutational

  3. Both (A) and (B)

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

Nutation is the bending movements executed by some plant organs such as stems, leaves, roots, etc, by which the part is inclined successively in various directions. Nutations are due to unequal rate of growth of different sides of the organ. Nutational movement includes all the movements in plants caused by growth in contrast to variation movements or movements produced by reversible turgor changes.

  1. Thigmotropism movement

  2. Chemotactic movement

  3. Thigmonasty

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

Seismonasty is the nastic movement of plants in response to mechanical stimuli like touch or vibration, which is characteristic of Mimosa pudica.

Touch me not plant shows ----- movement.

  1. Seismonastic

  2. Hyponastic

  3. Epinastic

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

Mimosa pudica is well known for its rapid plant movement. Like a number of other plant species, it undergoes changes in leaf orientation termed "sleep" or nyctinastic movement. The foliage closes during darkness and reopens in light. The leaves also close under various other stimuli, such as touching, warming, blowing, or shaking. These types of movements have been termed seismonastic movements. The movement occurs when specific regions of cells lose turgor pressure, which is the force that is applied onto the cell wall by water within the cell vacuoles and other cell contents. When the plant is disturbed, specific regions on the stems are stimulated to release chemicals including potassium ions which force water out of the cell vacuoles and the water diffuses out of the cells, producing a loss of cell pressure and cell collapse; this differential turgidity between different regions of cells results in the closing of the leaflets and the collapse of the leaf petiole.

Therefore, the correct answer is option A.

Non-directional movement of a plant part with respect to stimulus is a

  1. Tropic movement

  2. Nastic

  3. Both A and B

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

Plants exhibit two types of induced movements of curvature. These are namely tropic and nastic movements. The directional growth movements in which direction of growth is determined by the direction of stimulus are known as tropic movements. Examples: thigmotropism, phototropism, chemotropism, gravitropism etc. This makes option A incorrect. The non-directive growth movements of plants, wherein the direction of stimulus is not the determinant of the direction of movement, are known as nastic movements. These movements always occur in one direction. Examples: Seismonasty, photonasty, thermonasty etc. This makes option B correct. Thus, the correct answer is B.

When we touch the leaves of a touch-me-not plant, they bend down. This is an example of

  1. Thigmotropism

  2. Thigmonasty

  3. Phototropism

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

The leaves of touch-me-not plant show thigmonasty. Its leaves respond to vibrations when they are touched or shaken. The speed of the response depends on the magnitude of the stimulus. Flicking the leaf hard will cause the leaf to close faster whereas a gentle touch at the tip of a leaf will lead to a slower response. Thus the correct answer is option B.

Movement of _______ to stimulus of touch is called seismonastic movement.

  1. Mimosa

  2. Rose

  3. Lotus

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

On touching the Mimosa leaves the water concentration inside the plant changes due to which the plant leaves tend to get closed. This movement or response of plant is called seismonastic movement.
