Behavioral Psychology and Physiology Questions

Multiple choice physics the essence of change forms of energy and energy conservation energy for everything forms of energy

When you climb a staircase, you spend______ energy and gain ____energy.

  1. Kinetic - potential

  2. Chemical - electrical

  3. Muscular - kinetic

  4. Muscular - potential
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When someone climb staircase then he has to do so physical work, so some muscular energy is spemt, also if his relative position wrt earth chamges so some gain in kinetic energy of the body, body was initial at rest amd finaly at rest so no kinetic energy is gained or lost.

So best possible answer is option D.

Multiple choice biology nervous system of man divisions of nervous system autonomic nervous system the human brain

Which one of the following is the example of action of autonomous nervous system?

  1. Knee-jerk response

  2. Pupillary reflex

  3. Swallowing of food

  4. Peristalsis of the intestines
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Peristalsis of the intestines is the example of the action of the autonomous nervous system. The organs of our body (viscera), such as the heart, intestines and stomach, are regulated by a branch of the nervous system known as the autonomic nervous system. It consists of autonomic neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to glands, smooth muscle and cardiac muscle. ANS neurons are responsible for regulating the secretions of certain glands (i.e., salivary glands) and the regulation of heart rate and peristalsis (contraction of smooth muscle in the digestive tract), among other functions. So, the correct answer is option D.

Multiple choice biology nervous system of man divisions of nervous system autonomic nervous system the human brain

Which of the following is not an effect produced by parasympathetic stimulation?

  1. Pupil dilation

  2. Increased saliva

  3. Increased stomach activity

  4. Constriction of bronchi
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dilation of the pupil is the function of the sympathetic nervous system. Parasympathetic stimulation causes: slowing down of the heartbeat; lowering of blood pressure; constriction of the pupils; decreased heart rate; salivation increase; peristalsis of the GI tract.

Multiple choice biology nervous system of man divisions of nervous system autonomic nervous system the human brain

One of the examples of the action of the autonomous nervous system is

  1. Knee-jerk response

  2. Pupillary reflex

  3. Swallowing of food

  4. Peristalsis of the intestines

  5. All of the above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Esophageal peristalsis and sphincter function are controlled by the autonomic nervous system. Swallowing is a complex mechanism using both skeletal muscle (tongue) and smooth muscles of the pharynx and esophagus. The autonomic nervous system (ANS) coordinates this process in the pharyngeal and esophageal phases. Knee jerk is a sudden kicking of the lower leg after the tendon below knee cap has been tapped. The pupillary reflex is also controlled by autonomic nervous system.

Multiple choice zoology nervous system nervous systems involved in emotions types of nervous system components of nervous system

ANS affects the

  1. Reflex actions

  2. Sensory organs

  3. Internal organs

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

The autonomic nervous system (ANS), also known as the visceral nervous system and involuntary nervous system, is a division of the peripheral nervous system, that influences the function of internal organs. The autonomic nervous system is a control system, that acts largely unconsciously and regulates the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.

Which of the following is not an effect produced by parasympathetic stimulation?

  1. Dilation of the pupils

  2. Increased saliva production

  3. Increased stomach activity

  4. Constriction of the bronchi
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The parasympathetic nervous system decreases respiration and heart rate and increases digestion. Stimulation of the parasympathetic nervous systems results in the construction of pupils. Decrease heart rate and blood pressure.

So, the correct option is 'Dilation of pupil'.

Multiple choice physics the human eye and the colourful world human eye and its working what is inside our eyes? human eye and defects of vision

A series of fast moving still pictures can create an illusion of movement because.

  1. the eye can focus on very rapidly changing pictures

  2. eye is quicker than the brain

  3. the eye can separate two images only when the interval of separation between them is more than one-tenth of a second

  4. the optical cortex can see through the rapidly moving images
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Human eye cannot differentiate two images when the interval of separation between them is less than one-tenth of a second

Multiple choice zoology gas exchange in humans human respiration the mechanism of breathing breathing and its movements

What are correct about control of Broca area ?
1.Breathing 
2.Movement of vocal cords
3.Movement of teeth
4.Movement of tongue

  1. 1, 2, 3 correct

  2. 1, 2 correct

  3. 2, 4 correct

  4. 1, 3 correct
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Broca's area is primarily associated with speech production. It controls the motor movements of the tongue and vocal cords necessary for articulation.

Multiple choice biology our skeletal system and the skin bones and movements joints in the human body joints

The second vertebra, the axis which helps in a rotatory
movement of the head has a knob like process called

  1. Hypapophysis

  2. Metapophysis

  3. Odontoid process

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

First cervical vertebra is called atlas. Second cervical vertebra is known as axis. The atlas supports the head. Axis has a peg like process called Odontoid  process / Dens.

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

Fish are given food at the same time as a tap on their glass bowl and soon learn to approach when a tap sounds even in the absence of food.

  1. Reasoning/insight

  2. Imprinting

  3. Classical conditioning

  4. Habituation

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

Fish are given food at the same time as a tap on their glass bowl and soon learn to approach when a tap sounds even in the absence of food - it is an example of Classical conditioning.

Classical conditioning is a type of learning behaviour in which a potential stimulus is responsible for eliciting a response and is repeated many times.

Which of the following behaviour takes place in an animals life at a certain critical time?

  1. Dominance

  2. Reflex

  3. Instinct

  4. Imprinting

  5. Habituation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A form of learning that occurs during a brief genetically determined critical period shortly after birth is called as imprinting. Habituation occurs throughout the life where individual learn to ignore the irrelevant stimuli. Reflex is a response to external or internal stimuli experienced throughout the life. Instinct and dominance are innate behaviours. The correct answer is D.

Which among the following is a simple act of learning that involving loss of sensitivity to unimportant stimuli?

  1. Reasoning/insight

  2. Imprinting

  3. Classical conditioning

  4. Habituation

  5. Instinct
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Instinct is a kind of behaviour which does not involve any prior learning and is inherent and automatic. Thus, the loss of sensitivity to unimportant stimuli is a natural act which is instinctive in nature. For example, dancing of honeybees in the direction of food, animal fighting and courtship behaviour are are instinct behaviour.
