Explanation

• About Hemoglobin
• Transportation of oxygen is the function of hemoglobin.
• Iron is essential for the formation of hemoglobin.
• Hemoglobin molecule exhibits structural organization of proteins Quaternary Structure.
• Defeciency of Pyridoxine decreases hemoglobin production.
• Heme in haemoglobin is Protoporophyrin IX.
• Infants acquire adult hemoglobin level at End of first year.
• Ferric ion is not a part of hemoglobin molecule.
• Haemoglobin is found dissolved in the plasma.

Explanation

Uranium, especially Uranium-235, is a fissile material used as fuel in nuclear reactors.

It undergoes nuclear fission, releasing energy that powers turbines to generate electricity.

Explanation

All electromagnetic waves travel at the same speed through empty space

Electromagnetic waves are formed between electrical and magnetic fields due to vibrations.

Electromagnetic waves travel with the speed of light in free space.

The speed of light is  3*10^8 m/s

Hence, Electromagnetic waves travel at the speed of 3*10^8 m/s.

Explanation

• Hemodialysis is a medical procedure that filters and cleans the blood using a machine when the kidneys fail to perform this function effectively.
• It removes waste, toxins, and excess fluids from the bloodstream.

Explanation

Ozone (O₃) is a triatomic (three-atom) allotropic form of oxygen

Allotropy: is when an element exists in different forms in the same physical state. 

Oxygen: is the element in question. 

Ozone (O₃): is the specific allotropic form that contains three oxygen atoms in each molecule. 

Diatomic oxygen (O₂): is the other common allotrope of oxygen, containing two oxygen atoms per molecule. 

Explanation

Plasma constitutes 55% of human blood.

The remaining 45% consists of blood cells (red blood cells, white blood cells, and platelets).

Explanation

Carbon monoxide is a toxic gas that interferes with the blood's ability to carry oxygen, making it harmful to humans.

It can cause symptoms like dizziness, nausea, and even death if inhaled in high concentrations.

Explanation

A light year is the distance light travels in one year — about 9.46 trillion kilometers.

It is commonly used to measure vast distances between stars and galaxies.

Astronomers use an effect called parallax to measure distances to nearby stars.

Parallax is the apparent displacement of an object because of a change in the observer's point of view.

Explanation

All weather patterns are mainly caused by heating from the Sun.

It drives the movement of air and water in the atmosphere, influencing temperature, precipitation, and wind patterns.
