Reflection vs Refraction Reflection is a “mirror-like” representation of an object’s image being bounced back from another surface. Refraction is a change in direction of a state or an object due to a change of its speed. The change is visible when an object passes from one medium to another, depending on the angle of […]
Difference Between Mean and Median
The key difference between mean and median is that mean is the sum of total values in a data set divided by the number of values, while median is the middle value of a data set. We use mean and median to check the location of the data because they give an indication of a […]
Difference Between Sin and Cos
Sin vs Cos The branch of mathematics, which deals with sides and angles of triangle and trigonometric functions of these angles is called trigonometry. The basic trigonometric functions of an angle are sine (sin) and cosine (cos) of that angle. Trigonometric sin and cos are ratios of two specific sides in right angle triangle and […]
Difference Between Density and Specific Gravity
The key difference between density and specific gravity is that density is an absolute value, while specific gravity is a relative value for a substance. Density and specific gravity are the two commonly used terms that are often confused with each other. Particularly, in industries, these terms are widely important to weigh different substance and […]
Difference Between Metals and Non-metals
Metals vs Non-metals Over the span of several years, many scientists have stumbled across new and unknown substances which they have taken much time and effort to study and figure out— some of these materials have turned out to be beneficial and valuable to man’s needs, while others, interestingly, simply exist in the environment we […]
Difference Between Element and Compound
The key difference between element and compound is that elements can no longer be broken down, while compounds can be broken through chemical reactions. Both elements and compounds are extremely important in human life; they are present in nature and in man-made developments. Therefore, it’s important to know the difference between element and compound. CONTENTS […]
Difference Between Compound and Mixture
The key difference between compound and mixture is that the compound contains two or more components bound to each other by chemical means whereas the mixture contains two or more components bound to each other by physical means. A compound and a mixture, both contain two or more components. Nevertheless, these two chemical species differ […]
Difference Between Annual and Perennial Plants
The key difference between annual and perennial plants is that annual plants complete their life cycle in one season, especially during one year, while perennial plants grow and spread for more than two years, showing a longer life cycle. Any proud homeowner would like to have both annuals and perennials in his or her garden. […]
Difference Between T Lymphocytes and B Lymphocytes
The key difference between T lymphocytes and B lymphocytes is that the T lymphocytes originate in bone marrows and mature in the thymus while B lymphocytes originate and mature in bone marrows. The main two types of cells in blood are red blood cells (RBC) and white blood cells (WBC). RBC carries and transports oxygen […]
Difference Between DNA and RNA
The key difference between DNA and RNA is that DNA is a type of nucleic acid consisting of deoxyribonucleotides while the RNA is the second type of nucleic acid consisting of ribonucleotides. There are two main types of nucleic acids in a cell such as DNA and RNA. DNA stands for deoxyribonucleic acid while RNA […]
