Some osmoregulator like lobed fin fishes (Shark,rays,coelocanth)store organic compound within the body in order to increases $O.P$ of body fluid. These stored organ compound are-

  1. $TMO$ and uric acid
  2. $T.M.O$ and urea

  3. Urea and Hippuric acid

  4. Allentoin and urea.

B Correct answer
Explanation

Elasmobranch fishes like sharks, rays, and coelacanths retain high levels of urea and trimethylamine oxide (TMO or TMAO) in their body fluids to maintain osmotic equilibrium with the marine environment and protect their tissues from the toxic effects of high urea.

The mallard duck possesses a keeled sternum. What is the function of this specialised bone structure?

  1. To provide stability in water

  2. To provide a site of attachment for the large flight muscles

  3. To increase the body's surface area for heat exchange

  4. It is a weapon used in sexual competition between males
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A keel in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs.
In birds, the sternum (typically) has a keel-like projection to which the pectoral muscles attach; these muscles provide the all-important downstroke in powered flight. In contrast, flightless birds lack a keeled sternum -- if you don't have big, strong flight muscles, you don't need a keel to attach them to.

The supportive structure of our pinna is also found in _______________.

  1. Tip of nose

  2. Ear ossicles

  3. Vertebrae

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

  • The kind of tissue that forms the supportive structure in our pinna (external ears) is also found in tip of the nose. 
  • As External pinna is made up of elastic cartilage. 
  • It is passage towards middle ear. Hence, The supportive structure of our pinna is also found in the tip of the nose.
So, the correct answer is 'tip of nose'.

A joint made for power is

  1. Knee joint

  2. Suture in cranium

  3. Joint between vertebrae

  4. Mandibular joint
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The lower jaw is made up of a single bone called mandible.
  • The mandible is the longest and strongest bone in the face. It forms the lower jaw and holds the teeth in place.
  •  Movement of the lower jaw opens and closes the mouth and also allows for the chewing of food. The lower set of teeth in the mouth is rooted in the lower jaw.
  • The mandibular joint is a joint made for power. It connects the lower jaw bone to the skull.
  • So, the correct answer is 'Mandibular joint'.

The characteristics and an example of a synovial joint in humans is :

  1. Characteristics - Fluid cartilage between two bones, limited movements, Examples - Knee joint

  2. Characteristics - Fluid filled between two joints, provides cushion, Examples - Skull bones

  3. Characteristics - Fluid filled synovial cavity between two bones, Examples - Joint between atlas and axis

  4. Characteristics - Lymph filled between two bones, limited movement, Examples - Gliding joint between carpals
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
All articulations between bones that help in a certain kind of movement, are placed at a distance from each other to prevent friction between them during movement. This space between the two bones is filled with synovial fluid that also helps reduce friction. For example the ball and socket joint of the pelvic girdle, the pivotal joint between the atlas and the axis
So, the correct answer is 'Characteristics - Fluid filled synovial cavity between two bones, Examples - Joint between atlas and axis'

Which one of the following secretes a watery fluid for lubricating and cushioning the joint?

  1. Ligament

  2. Cartilage

  3. Tendon

  4. Synovial membrane
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements.
  • The synovial cavity is covered by the synovial membrane which secretes a watery fluid called synovial fluid for the lubricating and cushioning joint.
  • So, the correct answer is 'Synovial membrane'.

Synovial joints may be classified into subtypes according to

  1. Shape

  2. Amount of synovial fluid

  3. Number of bones

  4. Amount of cartilage
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Based on the movement ability, fibrous and cartilaginous joints are functionally classified as a synarthrosis or amphiarthrosis, the synovial joints are classified on the basis of shape.

So, the correct option is 'Shape'.
