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.

Which of the following animal's body shows bilateral symmetry?

  1. Starfish

  2. Jellyfish

  3. Earthworm

  4. Sponge

C Correct answer
Explanation

Bilateral symmetry means the body can be divided into identical left and right halves along a single plane. Among the choices, earthworms are annelids showing bilateral symmetry, whereas adult starfish are radially symmetrical, jellyfish are radially symmetrical, and sponges are mostly asymmetrical.

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.

Joint between metacarpals and phalanges is

  1. Ball and socket

  2. Pivot

  3. Saddle

  4. Hinge
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. 
  • A hinge joint (ginglymus) is a joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane. It is a type of synovial joint. For example, joint between metacarpals and phalanges is hinge.
  • So,the correct answer is 'Hinge'.

Ginglymoid/hinge joint occurs in

  1. Elbow and shoulder

  2. Elbow and knee

  3. Atlas and odontoid process

  4. Knee and ankle

  • A hinge joint (ginglymus) is a joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane.
  • The knee joint and elbow is a hinge joint/ ginglymoid i.e a type of synovial joint. 
  • So, the correct answer is 'Elbow and Knee'.

Largest synovial joint is

  1. Hip joint

  2. Knee joint

  3. Shoulder joint

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

A synovial joint is a connection between two bones which consists of a cartilage lined cavity filled with fluid. The knee joint is the biggest synovial joint in the human body. At the junction of the knee, the large femur bone of the thigh connects to both the tibia and fibula of the leg, as well as to the patella or knee cap. So, the correct answer is 'Knee joint'.

Synovial fluid is present in

  1. Spinal cavity

  2. Cranial cavity

  3. Freely movable joints

  4. Fixed joints
Reveal answer Fill a bubble to check yourself
C 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.
  • Synovial joints are freely movable joint. Hence synovial fluid is present in freely movable joint.
  • So,the correct answer is 'Freely movable joints'.

Friction is lessened in ball-and-socket joint by

  1. Coelomic fluid

  2. Synovial fluid

  3. Pericardial fluid

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

Synovial fluid is the pale yellow fluid that is present in every joint of the human body. It helps the bone able to slide past each other without causing damage to the ends of the bone. It means that synovial fluid lessens the friction in ball and socket joint. So, the correct answer is 'Synovial fluid'.
