12 Difference Between Ester And Ether (With Examples)

ester vs ether

Ester and ether are organic molecules with oxygen atoms. The main difference between ether and ester lies in their structure. An ester group requires two oxygen atoms and two carbon atoms to complete its characteristic structure, while an ether group only needs one oxygen atom and two carbon atoms for its structure. Read this article, to … Read more

Difference DNA And RNA [American Edition]


What Is DNA? DNA (Deoxyribonucleic acid) is a molecule composed of two chains that coil around each other to form a double helix carrying the genetic instructions used in the growth, development, functioning and reproduction of all known organisms and many viruses. The two DNA strands are also known as polynucleotides because they are composed … Read more

Difference Between Communicable And Non-Communicable Diseases [Notes & PDF]


A non-communicable disease (NDC) is a disease that is not transmissible directly from one person to another. The diseases are of long duration and generally slow progression. They include Parkinson’s disease, autoimmune diseases, strokes, most heart diseases, most cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Azheimer’s disease, cataracts and many more others. A communicable disease … Read more

12 Difference Between Cerebrum And Cerebellum (With Diagram)


Cerebrum Cerebrum is the principal and most anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres, (left and right) separated by a fissure. It is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in … Read more

Difference Between Bryophytes And Pteridophytes [American Edition]

bryophytes vs pteridophyte

What Are Bryophytes? Bryophytes are a group of plant species that reproduce via spores rather than flowers or seeds. Most of bryophytes are found in damp environments and lack specialized water-conducting tissues.  Examples of bryophytes include: liverworts, the mosses and hornworts. Many bryophytes usually have the following characteristics: The sporophytes of bryophytes are unbranched, producing … Read more

Rough vs Smooth Endoplasmic Reticulum: 15 Key Differences

Smooth Endoplasmic Reticulum

Endoplasmic Reticulum (ER) Cells have many organelles that work together to help them complete their life functions. One of those organelles is the endoplasmic reticulum, which is an interconnected network of membranes used to make proteins, steroids, and lipids located near the nucleus. The Endoplasmic reticulum creates, packages and secretes many of the products created by … Read more

15 Difference Between Replication And Transcription

Replication DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the basis for biological inheritance. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information or DNA as the parent … Read more

Difference Between Active Transport And Passive Transport (With Examples)

What Is Active Transport? Active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentration against the concentration gradient. Active transport uses cellular energy to move molecules against a concentration gradient. There are two types of active transport: Primary and Secondary active … Read more

Difference Between Euchromatin And Heterochromatin

Euchromatin and Heterochromatin

Euchromatin Euchromatin are chromosome material which does not stain strongly except during cell division. It represents the major genes and is involved in transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus (92% of the human genome is euchromatic). When observed under an optical microscope, euchromatin appears as light-colored bands. … Read more

Difference Between Convex And Concave Lens (With Examples)

Convex Vs Concave Lens

Convex Lens If a piece of glass or other transparent material takes on the appropriate shape, it is possible that parallel incident rays would either converge to a point or appear to be diverging from a point.  Therefore, a transmissive optical device that focuses or disperses a beam of light by means of refraction is … Read more
