Multiple choice biology habitat and adaptation terrestrial adaptations in plants desert ecosystem adaptation in terrestrial plants

Animals living in cold regions have?

  1. legs to run fast

  2. fat for additional insulation

  3. long necks

  4. long eye lashes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Animals that live in colder areas have to protect their bodies against extremely cold environmental conditions. Their bodies cannot withstand such cold climates. So, they have a thick white fur over their bodies. This provides an additional layer over their skin. As a result, the air gets trapped in this layer and it cannot pass through it, keeping their bodies insulated against the excessive cold.

So, option B " fat for additional insulation" is the correct answer.

Multiple choice bio-chemistry organization of life concept of metabolism metabolism in animals metabolism

It is much easier for a small animal to run uphill than for a large animal, because - ?

  1. small animals have lower $O _2$ requirement

  2. the efficiency of muscles in larger animal is less than in smaller animal

  3. it's easier to carry a small body weight

  4. smaller animals have higher metabolic rate
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
It has been observed that the metabolic rate of an organism is inversely proportional to its body weight, that is smaller animals have a higher metabolic rate. This higher metabolic rate allows them to have higher energy and are quicker in climbing heights as compared to larger animals.

So, the correct answer  is 'smaller animals have higher metabolic rate'.
Multiple choice physics medical imaging ultrasonic sound using ultrasound in medicine ultrasound and its applications

The technique used by bats to find their way or to locate food is ______.

  1. SONAR

  2. RADAR

  3. Echolocation

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

Bats can produce ultrasonic waves by flapping their wings.
They can also detect these waves.these waves produced by the bats after reflection from the obstacles like building guide them to  remain away from the obstacles during night with the help of ultrasonic waves.

Multiple choice physics medical imaging ultrasonic sound using ultrasound in medicine ultrasound and its applications

  1. By detecting reflection of ultrasonic sound

  2. By detecting refraction of ultrasonic sound

  3. By detecting reflection of infrasonic sound

  4. By detecting deflection of infrasonic sound
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

By detecting reflection of ultrasonic sound bats understands position and type of prey of any obstacle in way

Multiple choice biology skeleton and joints introduction to movement introduction to locomotion movement

A skull excavated from a place had large zygomatic arches, 2 pairs of large incisors, 2 pairs of premolars following a gap and 3 pairs of large molars. The foramen magnum was direction posterior. This skull belongs to a 

  1. Predatory mammal with bipedal locomotion

  2. Predaceous dinosaur with bipedal locomotion

  3. herbivorous mammal with Quadrupedal locomotion

  4. Herbivorous dinosaur with Quadrupedal locomotion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A skull excavated from a place had large zygomatic arches, 2 pairs of large incisors, 2 pairs of premolars following a gap and 3 pairs of large molars. The foramen magnum was direction posterior. This skull belongs to a mammalian skull because it is predatory mammal with bipedal locomotion.

So, the correct option is ‘predatory mammal with bipedal locomotion’.

Multiple choice types of circulatory system circulatory pathways transportation in plants and circulation in animals body fluids and circulation biology

Hepatic portal system is found in

  1. All mammals

  2. All amniotes

  3. All vertebrates

  4. Higher invertebrates

  5. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A) The hepatic portal system is the venous system that returns blood from the digestive tract and spleen to the liver. It is present in mammals.

B) Not all amniotes have a hepatic portal system.
C) The hepatic portal system is found in amphibians and mammals.
D) Higher invertebrates do not have a hepatic portal system.
E) Mammals have a hepatic portal system.
So the correct answer is 'All mammals'.

Multiple choice types of circulatory system circulatory pathways transportation in plants and circulation in animals body fluids and circulation biology

which of the following vertebrate organ systems does not open directly to the external environment?

  1. Digestive system

  2. Circulatory system

  3. Excretory system

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

The circulatory system is the only system which is not exposed to the external environment.

So, the correct option is 'Circulatory system'.

Multiple choice bio-chemistry lipids functions of lipids biomolecules: chemical constituents of living cells biochemistry

Which tissue is responsible for providing insulation to the body?

  1. Epithelial tissue

  2. Adipose tissue

  3. Fibrous connective tissue

  4. Nervous tissue

  5. Muscle tissue
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Adipose tissue, or fat, is an anatomical term for loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.

Multiple choice biology neural control and coordination human nose nose nose : the olfactory organ

The olfactory receptors in human body are found in 

  1. Skin

  2. Nose

  3. Throat

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

Olfactory receptors are found in nose. They are associated with the perception of smell. Olfactory receptors expressed in the cell membranes of olfactory receptor neurons are responsible for the detection of odor molecules. Activated olfactory receptors are the initial player in a signal transduction cascade which ultimately produces a nerve impulse which is transmitted to the brain.

Therefore, the correct answer is option B.

Multiple choice biology neural control and coordination human nose nose nose : the olfactory organ

Olfactory receptor organs are sensitive to

  1. Light

  2. Sound

  3. Smell

  4. Equilibrium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Olfactory receptors are also known as odorant receptors. 
  • They are present in the cell membranes of olfactory receptor neurons and are responsible for the detection of odour which gives rise to the sense of smell.
  • Hence,  Olfactory receptor organs are sensitive to Smell.
  • So, the correct answer is 'Smell'.
Multiple choice biology neural control and coordination human nose nose nose : the olfactory organ

Nasal chamber is divided into two parts by ____________

  1. $Sphenoid$
  2. $Palatine$
  3. $Mesethmoid$
  4. $Zygomatic$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The nasal chamber in mammals is divided into right and left halves by the nasal septum, a structure formed by the perpendicular plate of the ethmoid bone, the vomer, and the septal cartilage. Among the given skull bone options, the mesethmoid contributes significantly to this bony partition of the nasal cavity.
