Multiple choice biology animal tissue muscle tissue structure of protein muscle tissues

Contractile proteins are found in_________________.

  1. Bones

  2. Blood

  3. Muscles

  4. Cartilage

Explanation

From all the above options, only muscle has a property of contraction. Muscle possess contractile proteins named, acitn and myosin on myofibrils. Hence, option C is correct. 

Multiple choice biology adapting to a habit extreme adaptations adaptive features adaptations of organisms

The biological adaptation that allows frogs to obtain water for their survival during conditions of water scarcity is the

  1. Presence of modified tongue that acts like a sponge to suck water from damp soils

  2. Presence of water channels in the skin by which they absorb water from their surroundings

  3. Presence of ciliated oesophagus that helps in separating water from ingested particular matter

  4. Selective feeding on plants with large amount of water that would fulfill the water requirement
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In the conditions of water scarcity, the frogs show biological adaptation to reduce water loss or obtain water from the surroundings. The skin is modified to contain water channels. The water is absorbed from the surroundings through the skin and the water channels makes the water available for the survival. 

Thus, the correct answer is option B. 

Multiple choice physics study of sound conditions for hearing echo echo 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 study of sound conditions for hearing echo echo ultrasound and its applications

It has been seen that the behaviour of animals becomes unusual just before the tremor is felt.what is the reason behind this?

  1. Because animals are able to detect infrasonic waves produced at the time of tremor.

  2. Because animals are able to detect ultrasonic waves produced at the time of tremor.

  3. Because animals are able to detect audible waves produced at the time of tremor.

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

Has been seen that the behaviour of animals becomes unusual just before the tremor is felt.This is because animals are able to detect infrasonic waves produced at the time of tremor. Infrasonic waves are waves of frequency less than 20Hz.

Multiple choice biology windows of knowledge human tongue organ of taste tongue : the organ of taste

Each taste bud has a cavity with a pore called as the

  1. Gustatory pore

  2. Taste pore

  3. Papilla pore

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

Papillae give the tongue its rough texture. The surface of the papillae is covered by thousands of taste buds.
Taste buds have the taste sensors or the taste receptors inside them.
Each taste bud has a cavity with a pore called as the taste pore.
Inside each cavity is taste receptor cells or gustatory receptor cells, bathed in saliva.
Each receptor cell has a free hair-like cilium also called as the taste hair which projects into the outer taste pore.
Additionally, each receptor cell has a nerve fibre called as the gustatory nerve extending from its base to the taste centre of the brain.

Which of the papillae are not found in human?

  1. Fungiform papillae

  2. Circumvallate papillae

  3. Foliate papillae

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

Humans possess fungiform, circumvallate, and foliate papillae. Since all these are found in humans, the statement that none of the above are missing is technically true, or the question is flawed.

Which of the following separates the two parts of the tongue?

  1. Papillae

  2. Lingual septum

  3. Terminal sulcus

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

  • Terminal sulcus of the tongue is a V-shaped groove, with a posteriorly oriented apex, on the surface of the tongue, marking the separation between the anterior (oral or horizontal) and the posterior (pharyngeal or vertical) parts of the tongue. Hence, Terminal sulcus separates the two parts of the tongue.
So, the correct answer is 'Terminal sulcus'.

Which of the following is the supporting cell for taste receptor?

  1. Cuboidal cells

  2. Columnar cells

  3. Ciliated cells

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

The taste buds are comprised of two main type of cells, receptor cell and the supporting cell. The receptor cells are neurosensory. They have one free end and the other nerve ending travelling to the taste area of the brain. The supporting cells are the columnar cells. These cells are present between the receptor cells. These cells are about 40 in number. 

Thus, the correct answer is option B.

Which of the following states the location of taste buds on the tongue?

  1. Pouches

  2. Papillae

  3. Palate

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

  • Lingual papillae (singular papilla) are the small, nipple-like structures on the upper surface of the tongue that give it its characteristic rough texture.
  •  The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate. All except the filiform papillae are associated with taste buds. Hence, Papillae states the location of taste buds on the tongue.
 So, the correct answer is 'Papillae'.

Fungiform papillae carry which of the following cranial nerve?

  1. VII

  2. IX

  3. X

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Fungiform papillae contain taste buds (especially for bitter taste), temperature receptors and have a good blood supply. They are scattered over the top and sides of the tongue, mainly towards the tip.
  • Cranial nerves are the nerves which arise from the brain and spinal cord. The facial nerve is the 7th cranial nerve it arises from the pons of the brain stem.
  • The fungiform papillae are innervated by the VII cranial nerve. Hence through 7th cranial nerve fungiform papillae send sensory signals of taste to the brain stem.
  • So, the correct answer is 'VII'.

The cranial nerve that carries information of taste from epiglottis is

  1. VII

  2. IX

  3. X

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

The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves. The X nerve or vagus nerve carries information from the back of the oral cavity and the epiglottis.

So, the correct answer is option C.
