Explanation

Ascaris is a parasitic roundworm, not a mammal; it belongs to phylum Nematoda.

Mammals like lion, bat, and platypus feed their young with milk.

Explanation

Explanation

Gas molecules have very weak forces of attraction already, so breaking them does not require much energy.

Thus, "Less energy is required..." is NOT a unique characteristic describing their general behavior compared to solids or liquids.

Explanation

Helium hydride (HeH+) was the first molecule discovered in space, identified in 2019 by astronomers.

It was found in a planetary nebula, marking a significant discovery in molecular chemistry in space.

Explanation

Eduard Zirm performed the world's first successful human cornea transplant in 1905.

The operation restored vision to a man who had been blinded by a chemical burn.

Explanation

Rocket velocity is governed by the rocket equation, which depends on exhaust velocity and the rate of mass ejection.

Higher exhaust velocity and more mass loss (fuel ejection) produce greater thrust, resulting in higher rocket velocity.

Explanation

The Paschen series involves electron transitions ending at the third energy level (n=3) in a hydrogen atom.

These transitions emit photons in the infrared region of the electromagnetic spectrum.

Explanation

Iron is a magnetic material that can absorb and redirect magnetic field lines.

It shields precision instruments from external magnetic interference that could affect their accuracy.
