In contrast to inorganic catalysts, enzymes have an intricately shaped binding surface called the -  active site.

The correct option is c.

Proteins called enzymes aid in accelerating our bodies' chemical processes, or metabolism. Some compounds are created, while others are broken down. Enzymes are a part of all living things. Enzymes are created by our bodies spontaneously.

The vital function of enzymes is to reduce the activation energy of a process, or the amount of energy required for the reaction to start. In order to facilitate the chemical bond-breaking and bond-forming processes, enzymes bind to reactant molecules and keep them in place.

Metals and their oxides supported on porous materials are examples of inorganic catalysts, also known as heterogeneous catalysts, which imitate the exquisite function of enzymes found in nature's catalysts. Through adsorption, the reactants attach to the active sites on the metal surface.

The small intestine absorbs most of the nutrients in food.

The majority of the nutrients in your meal are absorbed in your small intestine before being transported by your circulatory system to other areas of your body for storage or utilization. A special type of cell helps nutrients pass through the gut lining and into the circulation. Simple sugars, amino acids, glycerol, certain vitamins, and salts are transported to the liver by your blood. When necessary, your liver processes, stores, and distributes nutrients to the rest of your body.

Fatty acids and vitamins are absorbed by the lymph system, a system of capillaries that transports white blood cells and a fluid called lymph throughout the body to fight infection.

Specific gravity indicates the amount of dissolved substances in the urine.

As it travels through the nephrons and down the renal tubules of the kidney, urea, along with water and other waste products, creates the urine. both ureters. From the kidneys to the bladder, urine travels through these tiny tubes. The excretory organs remove some additional, frequently poisonous compounds from the circulatory fluids and expel them from the body through urine, which is a liquid or semisolid solution of metabolic wastes. Urine often reflects an organism's needs for water in terms of composition.

The difference between an object's density and that of a standard substance is its specific gravity. Depending on its value, the specific gravity might indicate whether an object will float or sink in our reference substance. A laboratory test called urine specific gravity reveals the concentration of all chemical particles in the urine.

Having darker dorsal pigmentation and lighter ventral pigmentation is called countershading.

Many animals have countershading, which is characterised by a darker dorsal surface and a brighter ventral surface. Many people believe that the dorsoventral pigment polarity is an adaptive colouring for camouflage. In contrast, genetic colour polymorphism in terrestrial animals results in the frequent occurrence of noncountershaded (melanistic) morphs within a species.

Although it may also improve thermoregulation or provide UV protection, this dorsoventral pigment polarity is ecologically explained as an adaptation for camouflage through the concealment of self-shadow and/or background matching.

The 3'-end is single-stranded with a 14-16 base overhang. there are two reasons for the 3'-end being longer than the 5'-end. the first is that the g-t strand (3'-end) is extended by the telomerase enzyme. the second reason is the C-A strand (5'-end) is enzymatically degraded.

A telomere is the  region of repetitive DNA sequences at the end of a chromosome.

They protect the chromosome ends from DNA degradation, recombination, and DNA end fusions

The overhang in telomere is due to incomplete end replication.

They gets shorten during replication to avoid gene deletions.

the daughter chromosomes lose the 3′ overhang which was present in the parent and therefore, in the absence of telomerase this will accordingly result in the telomere shortening

if telomere are long, the cellular machinery result in a bit of telomere becoming looped off each time cells replicate DNA and divide,

The characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier is that each hemoglobin molecule can bind four oxygen molecules.

The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.

Hemoglobin is a two-way respiratory carrier that facilitates the movement of carbon dioxide back and forth from the lungs to the tissues. Hemoglobin's affinity for oxygen in arterial circulation is high, but its affinities for carbon dioxide, organic phosphates, hydrogen, and chloride ions are low.

Thus from above conclusion we can say that the characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier is that each hemoglobin molecule can bind four oxygen molecules.

Smaller single-celled organisms have a high surface-to-volume ratio, allowing them to survive by relying on waste disposal and oxygen diffusion. If the items have a higher surface area to volume ratio, this technique may work better.

Because cells are so tiny, they may optimise their surface area to volume ratio. More molecules and ions can pass the cell membrane per unit of cytoplasmic volume in smaller cells due to their greater ratio. The reason why cells are so little is so that they can swiftly take in nutrition and expel waste.
