  2. Scrotum

  3. Testis

  4. Prostrate

Testes are masses of coiled

  1. Uriniferous tubules

  2. Malpighian tubules

  3. Vasa efferentia

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

The tubular structures present inside the testis are known as seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis. 

The uriniferous tubule is  a urine-bearing tubule in a nephron of a kidney. Malpighian tubules are slender tubes normally found in the posterior regions of arthropod alimentary canals. 
Vasa efferentia is the several highly convoluted tubules that lead from the  testis. 
Therefore, the correct answer is option D.

Testes are placed inside the

  1. Abdominal cavity

  2. Urinary bladder

  3. Scrotum

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

The testes are located outside the abdominal cavity in a pouch of skin called the scrotum. This placement is essential because sperm production requires a temperature slightly lower than the core body temperature.

Head of epididymis present at head of testis is

  1. Caput epididymis

  2. Cauda epididymis

  3. Vas deferens

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

Head of the epididymis of the sperm which receives spermatozoa via the efferent ducts of the mediastinum of the testis which is also called as Caput epididymis.

So the correct option is 'Caput epididymis.'

Multiple choice botany the world of microbes bacteria - introduction, shape and structure bacteria: types and structure bacteria; benefits and harmful effects non cellular organism : virus world of virus

Which of the following is the location of mucilage capsule present in bacteria which serves as an extra covering?

  1. Outside the cell membrane

  2. Inside the cell membrane

  3. Outside the cell wall

  4. Inside the cell wall
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The mucilage capsule present in bacteria serving as an extra covering is present outside the cell because it is a temporary layer surrounding the cell wall and protects the bacteria from antibiotics and dessication.

So, the correct option is C.

Multiple choice zoology animal diversity - ii (phylum: chordata) aves and mammalia classifications of chordata aves

Cloaca is

  1. Common aperture for digestive and urinary systems

  2. Common aperture for digestive, urinary and reproductive systems

  3. Common chamber in which reproductive, urinary and digestive tracts open

  4. Common chamber for digestive and urinary tracts
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cloaca is a chamber or cavity that acts as an exit channel in organisms like reptiles, birds and amphibians.

It is a common chamber where reproductive, urinary and digestive tracts open.
So the correct answer is 'Common chamber in which reproductive, urinary and digestive tract open'

Multiple choice zoology the age of adolescence human respiration the mechanism of breathing breathing and its movements

Which structure gives us ability to speech?

  1. Epiglottis

  2. Vocal cord

  3. Larynx

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

The vocal cord has two small bands of muscle within the larynx. These muscles vibrate to produce the voice. It is a V shape inside larynx. When we talk, the vocal cord tightens up and move closer together and air from lungs forced between them and make then vibrate, producing the sound.

So the option B, Vocal cord is correct.

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

Choose the correct answer from the alternatives given.
Which of the following is the cartilaginous structure that folds down to meet the uprising larynx to close off the airway during swallowing?

  1. Trachea

  2. Epiglottis

  3. Cricoid cartilage

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

A flap-like epiglottis closes the opening to the larynx during swallowing to prevent swallowed matter from entering the trachea (airway). So, the correct option is 'Epiglottis'.

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

Choose the correct answer from the alternatives given.
In which of the following structures vocal cords are located?

  1. Oesophagus

  2. Larynx

  3. Pharynx

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

The vocal cords are folds of membranous tissue that are located within the larynx at the top of the trachea. Their edges vibrate in an airstream to produce voice. So, the correct option is 'Larynx'.
