Explanation

D 1 appears to refer to a specific genotype, D1.1, of the H5N1 avian influenza (bird flu) virus. 

The "H" stands for Hemagglutinin, and "N" for Neuraminidase — proteins found on the surface of the influenza virus.  

So, HX is associated with viruses, not bacteria, vaccines, or fungi. 

Explanation

This is Einstein’s famous mass-energy equivalence formula, where:  

- E = Energy  

- m = Mass  

- c = Speed of light (approximately 3 × 10⁸ m/s)

Explanation

A myopic defect can be corrected by using a concave lens of suitable power. 

Myopia is a disease related to Eye

Myopia is a common vision condition in which we can see objects near to us clearly, but objects farther away are blurry.

Myopia means دورکی نظر کی کمزوری

Explanation

Sugarcane generally has the longest cultivation-to-harvest period, taking 10 to 18 months (or even longer in some regions) to mature

Cotton: Around 5–6 months (a single growing season).

Rice: About 3–6 months (single season).

Wheat: Completes life cycle in one season (shorter than cotton/sugarcane). 

Explanation

Colour blindness is significantly more common in males than in females.

The other conditions listed are either more common in women or have a more complex relationship with gender. 

Explanation

Insulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

Explanation

Lithium is the lightest metal.

Density of 0.534 g/cm³.

It is an alkali metal,

The third element on the periodic table,

It is soft enough to be cut with a knife.

Uses: Due to its low density and high reactivity, it's used in aircraft and, famously, in the production of batteries for electric vehicles and consumer electronics. 

Explanation

The least count of a Vernier caliper is 0.02mm.

It is the smallest measurement that can be accurately read using the instrument.

It is derived from the difference between one main scale reading and one Vernier scale reading.

It is commonly used to accurately measure outside diameters of shafts, thicknesses of various parts, diameters of holes or rings, internal dimensions of hollow jobs, and depths of holes or steps. 

Explanation

Studies show that it takes an average of 8 minutes and 20 seconds for sunlight to move from the sun to the earth.

Sunlight moves at the speed of light.

You can see that the distance of the sun from the earth = 149.6 x 106 km.

Photons emitted from the surface of the sun need to traverse the vacuum of the universe to reach our eyes.
