Bacteria are prokaryotic, unicellular microorganisms which are characterized by their simple cellular structure and lacks membrane-bound organelles such as a nucleus, mitochondria, and Golgi bodies.
Osmosis and diffusion are fundamental processes that govern the movement of molecules in biological and physical systems. Both are passive transport mechanisms, requiring no external energy input, but they differ in the type of molecules they transport, the mechanisms they utilize, and their specific roles in maintaining cellular and systemic homeostasis. These processes are essential for the survival of living organisms, influencing everything from cellular hydration to gas exchange and nutrient distribution
The main difference between Prokaryotic and Eukaryotic cells is that eukaryotes have a true nucleus and membrane-bound organelles whereas prokaryotic cells do not.
Microbes or microorganisms are microscopic organisms (i.e., they are not visible to naked eye) that exist as unicellular, multicellular, or cell clusters. Microorganisms are widespread in nature (they make up almost 60% of the earth’s living matter) and are beneficial to life, but some can cause serious harm.
DNA exists in multiple structural conformations, of which the A, B, and Z forms are the most well-known. These forms arise due to variations in helical structure, environmental conditions, and sequence-specific factors. Each form exhibits unique properties that significantly influence DNA’s biological function, adaptability, and interactions with proteins and other molecules. Understanding these differences is essential for insights into DNA’s role in genetic regulation, stability, and evolution.
What are the differences between DNA and RNA? Following are the differences between DNA and RNA -: Criteria DNA (Deoxyribonucleic Acid) RNA (Ribonucleic Acid) Full Form Deoxyribonucleic Acid Ribonucleic Acid Sugar Deoxyribose Ribose Structure Double-stranded (helix) Single-stranded Nitrogenous Bases Adenine, Thymine, Cytosine, Guanine Adenine, Uracil, Cytosine, Guanine Location Nucleus (mainly), Mitochondria Cytoplasm, Ribosome, Nucleus Function … Read more
Endocrine System consists of ductless glands that control, communicate, coordinate and integrate various functions of all the body organs by secretions of chemical messenger called hormones.
The system that controls and coordinates all the activities of various body parts in response to external and internal stimuli by the conduction of nerve impulses is called nervous system.
All the portal veins that carry their contents into liver collectively constitute the Hepatic Portal System.
The process of removal of chemical waste (mainly nitrogenous) from the body is known as excretion and the organ system involved is called Excretory System.
