The respiratory disease which is diagnosed during childhood, resulting in shortness of breathing, dryness of a cough, chest tightening is called asthma. On the other hand, COPD also known as Chronic Obstructive Pulmonary Disease is also one of the respiratory disease, which occurs after the age of 4o, and the condition gets progressively worse with age. The cell's of our body need oxygen to work and grow, and this oxygen is taken by the lungs through the simple process of breathing. Usually, … [Read more...]
Difference Between Nervous System and Endocrine System
The significant difference between these two is that the nervous system uses electrical signals or impulses to send the signals through neurons, while the Endocrine system uses hormones acting as the chemical messenger to send signals to the target cell through the blood stream in the body. However, both are the regulatory system allows the communication between the tissue, organs, and cells. These systems have the responsibility to control and coordinate the signals given to the body, … [Read more...]
Difference Between Plasma and Serum
Plasma is that part of the blood, which contains blood clotting agent called as fibrinogen, while serum is the fluid part of the blood and does not contain clotting agent. The plasma and serum can be extracted from the centrifugation of blood. The serum is obtained after the clotting of blood, while plasma can be obtained before the coagulation of the blood. Centrifugation separates the blood components by its weight, size, and density. The fluid circulating in the body through arteries and … [Read more...]
Difference Between Osteoarthritis and Rheumatoid arthritis
Nature and the cause are the main difference between the osteoarthritis and rheumatoid arthritis. Osteoarthritis is the kind of degenerative condition, while rheumatoid arthritis is a kind of autoimmune disease, where the body itself attacks the body's joints. Osteoarthritis is due to the increased wear and tear on joints, whereas rheumatoid arthritis produces the inflammation of the joints throughout the body, also resulting in fever and severe fatigue. There are many forms of arthritis like … [Read more...]
Difference Between Heterochromatin and Euchromatin
The major difference between heterochromatin and euchromatin is that heterochromatin is such part of the chromosomes, which is a firmly packed form and are genetically inactive, while euchromatin is an uncoiled (loosely) packed form of chromatin and are genetically active. When the non-dividing cells of the nucleus were observed under the light microscope, it exhibited the two regions, on the ground of concentration or intensity of staining. The dark stained areas are said as heterochromatin … [Read more...]
Difference Between Hepatitis and Jaundice
Hepatitis is said to be the inflammation of the liver cells due to the attack of virus, bacteria, parasites, drugs, ischemia, toxins, etc. On the other hand, when there is surplus deposition of the bile pigment in blood especially of bilirubin, resulting in the yellow discoloration of the eye (sclera), skin, it is called as Jaundice. Hepatitis is the liver disease, while jaundice is a sign of the increased production of a yellow pigment called bilirubin in the blood. Hepatitis and jaundice … [Read more...]
Difference Between Inhalation and Exhalation
The inhalation and exhalation are the two basic mechanisms involved in the process of breathing. These processes facilitate the exchange of oxygen and carbon dioxide. During the process of inhalation, the diaphragm contracts and moves in a downward direction. And the ribs move outwards and upwards. These movements cause an increase in the intrapulmonary volume and the expansion of the thoracic cavity. As the volume inside increases, the intrapulmonary pressure falls down. So, in order to … [Read more...]
Difference Between Hypothyroid and Hyperthyroid
The condition when the thyroid gland produces less amount of thyroid hormones is called hypothyroid, while the condition when there is the overproduction of hormones by the thyroid gland is called hyperthyroid. The thyroid gland is located in a front portion of the neck and affects almost whole body's metabolic process. The main function of thyroid gland is to store, secrete, and produce hormones especially triiodothyronine (T3) and thyroxine (T4) into the bloodstream that regulates numerous … [Read more...]
Difference Between Homozygous and Heterozygous
Individual organisms carrying two identical alleles (for example RR or rr) are called as homozygous. While individual organisms bear different alleles (for example Rr) are called heterozygous. A homozygous trait is when the same kind of two alleles associate to form a trait. A heterozygous is a trait when different kinds of two alleles associate to form a trait. In this type, dominant and regressive alleles are present in the pair, and the dominant will represent the kind of trait the … [Read more...]
Difference Between Replication and Transcription
Replication is processed inside the nucleus and involves the copying of the genetic material so that the new daughter cell thus form contains the identical copies as their parent cells. While transcription is processed in the cytoplasm where a segment of DNA is transcribed into RNA. Both the process occurs inside the cell. The flow of biological information from DNA to RNA and then synthesis of proteins is considered as the 'central dogma of life'. These involve the three main processes which … [Read more...]
