A Correct answer
Explanation

Group 1 represents various members of the Phylum Platyhelminthes while Group 2 includes members of class Aves of vertebrata.

Pinworm and Crow are included in Phylum Platyhelminthes and Aves respectively.
So, the correct option is 'X - Pinworm, Y - Crow'.

Ubisch bodies are connected with the formation of?

  1. Sporopollenin

  2. Intine and pollenkitt

  3. Exine

  4. Pollenkit and pollinia
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
When the anther is young, at the stage of sporogenous tissue, the cells of the tapetum contain numerous spherical bodies called pro-ubisch bodies. The number of pro-ubisch bodies increases by meiosis in Pollen mother cells. These pro-ubisch bodies get coated by sporopollenin and are called ubisch bodies or orbicules. These are involved in the formation of exine of the pollen grains. Thus, the correct answer is option C, Exine.

Unlike animals, plants get energy in the form of

  1. ATP

  2. Soil

  3. Roots

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

Chloroplasts contain a pigment called chlorophyll. Chlorophyll is able to capture the energy from the sun. In doing this, a series of chemical reactions occur that convert the sun's energy into ATP (energy for the plant). 

Therefore, the correct answer is option A.

Which one is unrelated?

  1. Ca muscle contraction

  2. I thyroid

  3. Co energy liberation

  4. Cl nerve conduction
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Calcium is involved in muscle contraction, Iodine is essential for thyroid function, and Cobalt is part of Vitamin B12 (energy metabolism). Chlorine is an electrolyte, but the pairing 'Cl - nerve conduction' is less specific or standard compared to the other biological roles listed.

Myelin sheath of nerve fibres is produced by

  1. Axon

  2. Connective tissue

  3. Schwann cells

  4. Neuroglia
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Myelin is a layered substance made of phospholipid, cholesterol and protein that covers the axons of the neurons.
  • It insulates the nerve impulses from the surrounding nerve fibres. 
  • It also increases the speed of impulses through nerve axons.
  • It is formed in the central nervous system by glial cells called the oligodendrocytes.
  • Whereas, in the peripheral nervous system they are produced by Schwann cells.
  • So, the correct answer is 'Schwann cells'.

Myelin sheath has layers of fat and protein

  1. Upto 100

  2. 10-20

  3. Two each

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

  • Myelin is an insulating layer or sheath that forms around nerves, including those in the brain and spinal cord.
  •  It is made up of protein and fatty substances. 
  • This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells.
  •  If myelin is damaged, these impulses slow down. Hence, the Myelin sheath has layers of fat and protein up to 100.
So, the correct answer is 'up to 100'.

The characteristic of a nerve cell that relates directly to its function is its-

  1. Long extensions.

  2. Flat shape.

  3. Ability to change shape.

  4. Ability to engulf bacteria.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The long extensions of a nerve cell (axons and dendrites) are essential for its function of transmitting signals over long distances within the body.
