The First Law of the Thermodynamics is related to the conservation of energy, while the Second Law of Thermodynamics argue that some of the thermodynamics processes are impermissible and does not entirely follow the First Law of Thermodynamics. The word 'thermodynamics' is derived from the Greek words, where "Thermo" means heat and "dynamics" means power. So thermodynamics is the study of energy which exists in various forms like light, heat, electrical and chemical energy. Thermodynamics … [Read more...]

Compounds and mixtures are two important categories of matter. The mixtures, on one side, are formed by the physical mixing of one or more than one substances. Whereas the compounds are produced by chemical interaction at the molecular level. There is a proper chemical bonding between two or more elements at the time of compound formation. But no such thing occurs in the case of the mixture, as there is no chemical reaction between the components. The mixtures have no such decided ratio of … [Read more...]

Piles or Hemorrhoids are the swollen veins in the lower part of the anal canal or anus, these are painless. Fissures are very painful, as they are caused due to the tear or cut in the skin near the anus. The fistula is the small opening develops in the skin around the anus, this opening has pus inside it. Most people do not know the exact difference between the three, as they think that if they have certain kind of pain or bleeding in their anal part, it could pile, but few of them know that … [Read more...]

Mitosis has the diploid number of chromosomes and produces two identical daughter cells with 46 chromosomes, on the contrary in Meiosis four genetically distinct daughter cells with each having 23 chromosomes in the human cells are produced which have the haploid number of chromosomes. Secondly, Mitosis occurs in Somatic cells while Meiosis happens in Sex cells or Gametic cells. The above points are the critical one to distinguish between the two, though there are many more to focus, which … [Read more...]

The phenotype is the physical appearance of an organism, while the Genotype is the genetic composition of an organism. Phenotype is observable and are the expression of the genes of an individual. So even the organism with the same species may differ, with a minute difference in their genotype. This is the main difference between the two. We can notice one's hair colour, eye colour, height, weight, skin colour, etc. but cannot look at genes responsible for these characters, so the observable … [Read more...]

Any matter can undergo two types of changes: Physical or Chemical changes. The physical changes are those actions that generate no new substance. Instead, the older substance only changes in its size, structure and sometimes texture. Whereas the chemical changes give rise to a very new substance. And the older one loses all its characteristic properties. The physical changes are reversible as the original matter can be brought back together after proper treatment. They are a temporary type of … [Read more...]
