Explanation

Leukemia is a cancer of the body's blood-forming tissues.

Including the bone marrow and the lymphatic system.

Some forms of leukemia are more common in children.

Explanation

On and Upon

On = (Placed in contact)

Upon = (In Motion)

The books were on the table

The dog jumped upon the cat.

Explanation

 The dimensions of Planck's constant are the same as those of angular momentum. 

Planck's constant (h) is a fundamental constant in quantum mechanics

It relates the energy (E) of a photon to its frequency (ν) through the equation E = hν.

The dimensions of Planck's constant can be derived from this relationship,

And they are found to be the same as those of angular momentum

Explanation

The yellowing of leaves due to lack of chlorophyll is called chlorosis.

This condition occurs when the green pigment, chlorophyll, is reduced or absent in the leaves, causing them to turn yellow. 

Explanation

Appreciable means نوٹ کرنے یا ناپنے کے لیے بڑے یا کافی اہم

Measurable means نوٹ کرنے یا ناپنے کے لیے بڑے یا کافی اہم

Explanation

In pair production, several quantities are conserved

Let's evaluate each option:

- Charge:

A charge is conserved in pair production, as the total charge before and after the interaction remains the same

Due to the opposite but equal charges of the electron and positron.

- Energy:

Energy is conserved in pair production, with the total energy before the interaction equal to the sum of the energies of the electron and positron after the interaction.

- Linear Momentum:

Linear momentum is conserved in pair production, with the total momentum before the interaction equal to the sum of the momenta of the particles involved.

Explanation

The primary mode of movement in zooflagellates is flagellar movement.

Zooflagellates, also known as flagellates, are protozoa that use one or more flagella for locomotion.

These flagella are whip-like appendages that propel the organism through their environment.

Explanation

Chemiosmosis is the process where ATP is generated by using the energy stored in a proton gradient across a membrane.

In the context of photosynthesis, this proton gradient is established across the thylakoid membrane in the chloroplast.
