Explanation
The s tratospheric ozone layer  is Earth's “ sunscreen ”  protecting living things from too much  ultraviolet  radiation from the sun. Oxygen layer in the  atmosphere Ozone   protects  us from the harmful ultraviolet radiation of the sun. Ozone  formula : O3 The ozone layer lies approximately  15-40 kilometers  (10-25 miles) above the Earth's surface, in the stratosphere. The ozone layer is  depleting : Air pollution

Explanation
Vitamin D deficiency can cause Rickets , a disease characterized by: Soft and weak bones Skeletal deformities Stunted growth Increased risk of fractures

Explanation
Iron  is essential for the formation of hemoglobin. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Question About  Hemoglobin Hemoglobin  combines  with  red blood cells  and transports to different cells of the body. Hemoglobin molecule  exhibits  structural  organization of proteins Quaternary Structure. The  main constituent  of hemoglobin is: Iron The  transportation  of  oxygen  is the  function  of  hemoglobin . A  deficiency  of  Pyridoxine   decreases hemoglobin production. The heme  in hemoglobin is Protoporophyrin IX. Infants  acquire adult  hemoglobin levels at   the End of the first year. Ferric ion  is  not a part  of the hemoglobin molecule. Haemoglobin  is  found  dissolved in the plasma.

Explanation
Heat is a form of energy , specifically thermal energy , which is transferred from one body to another due to a temperature difference. It is a type of kinetic energy , where the particles of a substance vibrate or move rapidly, generating heat.

Explanation
The pH of pure water (H20) is 7 at 25 °C pH  stands  for " Potential Hydrogen" while Blood is  normally slightly basic,  with a  normal pH  range of about  7.35 to 7.45.

Explanation
The biosphere is the global ecological system integrating all living organisms ( biotic ) and their interactions with the non-living ( abiotic ) components (e.g., air, water, soil). It spans from the deepest oceans to the atmosphere , encompassing all ecosystems where life exists.

Explanation
Anatomy is the general term used for studying the internal structure of plants and animals. Phytotomy is specifically the plant anatomy — a branch of botany dealing with internal plant structures .

Explanation
Mitochondria is known as powerhouse of cell because it serves as site for synthesis of Adenosine Triphosphate (ATP) , the energy currency of cell , through the process of aerobic cellular respiration. ATP serves as energy currency for different cell activities. A cell consists of three parts : 1. The cell membrane , 2. The nucleus, and, 3. Between the two, the cytoplasm .

Explanation
Herbivores : These animals eat only plants. The word " herbivore " comes from the Latin words " herba " ( meaning plant ) and " vorare " ( meaning to eat ). Detritivores : These animals eat decaying organic matter. Omnivores : These animals eat both plants and animals .  Carnivores : These animals eat only meat . 

Explanation
The word " Trigonometry " comes from Greek: " trigonon " (triangle) and " metron " (measure). It deals with the relationships between angles and sides of triangles. The title of "father of trigonometry" is Hipparchus of Nicaea.

Explanation
By definition in mathematics, 0! = 1 . It helps maintain consistency in formulas like permutations and combinations .

Explanation
√2 cannot be written as a ratio of two integers , so it is an irrational number. Its decimal form is non-terminating and non-repeating (≈ 1.414...).

Explanation
Let's compare the fractions to 0.5 : 1/2 = 0.5 (exact match)
